The best Singapore virtual phone number provider for SMBs in 2026 is the one that sells the exact +65 number type a business needs, publishes the price and IMDA paperwork up front, and logs every call into tools like HubSpot or Salesforce. A Singapore virtual phone number lets a small team answer and place calls on a +65 line from a laptop or mobile app, with no desk phone or local office.
Singapore virtual numbers are not interchangeable. A +65 3 national number, a +65 6 landline, an 800 toll-free line and a +65 8 mobile number each carry a different price, document check, setup time and SMS limit. A provider that advertises a cheap "Singapore number" may only sell SMS-only mobile numbers, which cannot take a single voice call.
How were these Singapore virtual number providers ranked?

Each Singapore virtual number provider was scored from 1 to 5 on four criteria, and each score was multiplied by the criterion's weight. The four weighted scores add up to a final score out of 5. The weights reflect what decides whether a Singapore number actually works for an SMB, in order of how hard each problem is to fix after purchase.
Every score is based only on what the provider publishes on its own website: number pages, pricing pages, integration directories and help articles. A feature or price that is hidden behind a "contact sales" button scores as missing, because an SMB comparing providers cannot see it before signing up either.
Singapore number coverage (30%)
Singapore number coverage carries the highest weight because the number type decides whether the line can do its job at all, and it is the hardest choice to undo. Fixing a wrong number type usually means buying and verifying a second number, because several providers cannot port Singapore numbers in or out. Businesses evaluating international calling solutions can also explore cloud business phone systems to compare number availability, porting options, and calling features across providers.
- 5: sells all four types (+65 3, +65 6, 800 and +65 8) with public prices, document rules and setup times
- 4: sells three or four types or supports porting, but publishes only part of the pricing or document rules
- 3: sells Singapore numbers, but only one or two types are priced or the types are not specified
- 2: includes a Singapore number in the plan without saying which type or what it costs
- 1: no Singapore numbers
Calling and AI features (25%)
Calling and AI features carry the second-highest weight because they decide how many calls a small team misses or wastes each day. IVR and queues route callers to the right person, dialers raise the number of outbound calls per rep, and an AI voice agent answers after hours when a three-person team is offline.
- 5: a full inbound and outbound toolset (IVR routing, queues, recording, click-to-call or a dialer) plus an AI voice agent or AI call analysis
- 4: a full toolset for one direction of calling only, or for both directions without meaningful AI
- 3: PBX basics such as forwarding, voice greetings and recording, with no dialer
- 2: forwarding and voicemail only
- 1: number only, with no calling features
SMB pricing (25%)
SMB pricing carries the same weight as features because a two- or three-person team feels seat minimums and setup fees far more than a large company does. A $19 plan with a three-user minimum is a $57 monthly bill for a solo founder, and a monthly floor of $90 can cost more than the number itself is worth to a business testing Singapore.
- 5: public prices, no seat minimum, and a free plan, no subscription at all, or an entry price under $10
- 4: public prices, a free trial and no seat minimum, but an entry price of $10 or more or one-time activation fees
- 3: public prices, but a two- or three-seat minimum or regulatory fees added on top
- 2: a minimum monthly spend of $90 or more
- 1: no public pricing
Integrations (20%)
Integrations carry the lowest weight because many SMBs buying their first Singapore number do not run a CRM yet, and Zapier can bridge some gaps. Integrations still matter for any team that already uses HubSpot, Salesforce or a helpdesk, since native call logging removes manual note-taking after every call. Businesses can simplify call management and eliminate manual data entry with CRM-integrated VoIP phone systems, which automatically log calls and sync customer information with supported CRM platforms. OutRight Store
- 5: 100+ native integrations, including HubSpot and Salesforce
- 4: 50+ native integrations available on each plan, including HubSpot and Salesforce
- 3: 20 to 50 native integrations, or one certified CRM app plus Zapier
- 2: Zapier only
- 1: no integrations
Final scores
The final score is calculated as (coverage × 0.30) + (features × 0.25) + (pricing × 0.25) + (integrations × 0.20). For CloudTalk, that is (5 × 0.30) + (5 × 0.25) + (4 × 0.25) + (5 × 0.20) = 4.75.
| Provider | Coverage (30%) | Features (25%) | Pricing (25%) | Integrations (20%) | Final score |
| CloudTalk | 5 | 5 | 4 | 5 | 4.75 |
| CallHippo | 4 | 4 | 5 | 4 | 4.25 |
| JustCall | 4 | 5 | 3 | 5 | 4.20 |
| Ringover | 4 | 4 | 3 | 5 | 3.95 |
| RingCentral | 3 | 5 | 3 | 5 | 3.90 |
| Zadarma | 4 | 3 | 5 | 3 | 3.80 |
| Aircall | 3 | 5 | 2 | 5 | 3.65 |
| Sonetel | 3 | 3 | 5 | 2 | 3.30 |
| FreJun | 2 | 4 | 4 | 3 | 3.20 |
Because coverage carries 30%, one point on coverage moves a final score by 0.30, more than one point on any other criterion. That is why Zadarma (4 on coverage, 3 on features) finishes above Aircall (3 on coverage, 5 on features): Aircall's strong features cannot offset weaker published Singapore coverage plus a pricing score of 2.
Review-site ratings and company size were not scored. Ratings mix users from every country and rarely say anything about Singapore numbers, and company size does not change whether a +65 line works for a small team.
How do the top Singapore virtual number providers compare?
| Rank | Provider | Score | Singapore number from | Entry plan (per user/month) | Monthly cost for a 2-person team |
| 1 | CloudTalk | 4.75 | $6/month (+65 3) | Starter $25 (annual) | $56 |
| 2 | CallHippo | 4.25 | Priced in dashboard | Basic free; Starter $19 | $38 plus number fee |

| 5 | RingCentral | 3.90 | Included with plan | Core $20 (annual) | $40 plus taxes and fees |
| 6 | Zadarma | 3.80 | $7.50/month (+65 3) | No subscription | $7.50 plus call minutes |
| 7 | Aircall | 3.65 | 1 number included | Essentials $30 (annual, min. 3) | $90 (3 licenses billed) |
| 8 | Sonetel | 3.30 | $5.99/month (+65 3) | Premium $9.95 (annual) | $19.90 (numbers included) |
| 9 | FreJun | 3.20 | Included with plan | Standard $14.49 | $28.98 |
The two-person cost uses each provider's entry plan with seat minimums applied and one Singapore number. It excludes per-minute call charges and taxes, and all prices are in USD.
The 9 best Singapore virtual phone number providers for SMBs in 2026
1. CloudTalk (4.75/5): best for SMBs that want every +65 number type in one phone system

CloudTalk is the best Singapore virtual phone number provider for SMBs that want all four +65 number types, from a $6 national line to an 800 toll-free number, inside a complete business phone system and an AI voice agent platform rather than a bare number with call forwarding. A three-person sales or support team gets local caller ID, smart routing, CRM call logging and an AI voice agent in one app. Businesses comparing phone-enabled CRM solutions can also explore CRM software with built-in calling features to understand how integrated telephony supports sales communication and customer management.
CloudTalk ranks first because it is the only provider in this comparison that sells all four Singapore number types and publishes the price, required documents and setup time for each one. A +65 3 number goes live once documents are approved, while a +65 6 landline needs an ACRA BIZfile extract and 10 to 15 business days. CloudTalk also states 99.999% availability, or under six minutes of unplanned downtime a year.
Key features
- Call Flow Designer for building IVR menus and routing rules without code
- AI voice agent (AIVA) that answers 24/7 and books meetings in 70+ languages
- IVR, ring groups, queues and skill-based routing on Essential
- Power dialer (included in Expert) and parallel dialer that rings up to 10 lines at once
- Call recording, live monitoring, wallboards and custom dashboards
- AI conversation intelligence with transcripts, summaries, call scoring and sentiment analysis
Integrations
- CRM with automatic call logging, recordings and click-to-call: HubSpot, Salesforce, Pipedrive, Zoho CRM and Microsoft Dynamics 365, plus Freshsales and monday.com

- Recruiting and automation: Workable, Greenhouse and Bullhorn for candidate calls, plus Microsoft Teams, Zapier, Make and a public API; 100+ integrations in total
Use cases
- Outbound prospecting from HubSpot or Salesforce lists on a +65 3 caller ID, with the parallel dialer ringing up to 10 numbers and logging every outcome
- Time-zone coverage: the AI voice agent answers the +65 line and books meetings while a Europe- or US-based team is offline
- One shared 800 support line answered by several agents through queues, with each call attached to a Zendesk or Freshdesk ticket
Industries
- E-commerce and retail: with Shopify or BigCommerce order data on screen, one team handles order questions and calls about failed deliveries
- SaaS and technology: AI conversation intelligence scores demo calls, so managers coach reps without listening to every recording
- Recruitment and staffing: agencies run candidate shortlists through the power dialer, and each call stays on the profile in their ATS
Who CloudTalk is for
- Growing SMBs of roughly 3 to 50 users that run sales and support on one phone system, with one +65 number routing new business to reps and customers to support
- Companies selling into several markets, since CloudTalk offers local numbers in 160+ countries and Singapore can sit next to other markets in one account
Who CloudTalk is not for
- Individuals who only need a cheap number for OTP codes, since CloudTalk's +65 8 mobile number costs $110 a month and cannot make voice calls
- Businesses that need to keep an existing Singapore number, because CloudTalk does not currently port Singapore numbers
Pricing
- Singapore numbers: +65 3 $6/month; 800 $15/month (+$15 setup); +65 6 $15/month (+$95 setup); +65 8 $110/month
- Starter: $25/user/month billed annually, from 1 user
- Essential: $29/user/month billed annually
- Expert: $49/user/month billed annually, minimum 3 users

2. CallHippo (4.25/5): best for budget-conscious teams that want a free base plan

CallHippo is the best Singapore virtual number option for SMBs that want to start with zero subscription cost. The Basic plan is free and charges only for numbers and usage, and paid plans have no seat minimum, so a one-person team can upgrade to Starter at $19 a month without paying for empty seats. Small businesses comparing affordable calling solutions can also explore business phone systems for small teams to evaluate pricing, seat requirements, and features before choosing a provider.
CallHippo ranks second because it pairs the lowest entry cost with broad Singapore coverage. CallHippo sells local +65, toll-free and mobile (+65 8 or 9) numbers, and it ports existing Singapore numbers, which several providers in this comparison cannot do.
Key features
- Global Connect for running local numbers in several countries from one account
- Power dialer for outbound calling
- Voicemail transcription
- Call barging and call conferencing
- Call analytics
- Smart Switch carrier routing and SIP trunking
Integrations
- CRM with call logging: Salesforce, HubSpot, Zoho, Microsoft Dynamics and Bitrix24, plus Copper, Kommo, Insightly, ActiveCampaign, Keap, LeadSquared, monday.com, Attio and Vtiger
- Helpdesk and IT service: Zendesk, Freshdesk, Freshservice, Intercom, Front, Gorgias, Help Scout, HappyFox and ServiceNow
- 120+ integrations listed in total, with 50+ available on each paid plan (Starter, Professional and Ultimate)
Use cases
- Keeping an existing Singapore number when leaving a local carrier: the number ports into CallHippo, so business cards and Google Business listings stay valid
- Overseas teams calling Singapore and neighbouring markets from one account, with Smart Switch moving calls to another carrier when call quality drops
- A toll-free support line for Singapore customers, with each call tied to a Zendesk, Freshdesk or Help Scout ticket
Industries
- BPO and outsourcing: call barging and conferencing let supervisors join live calls on Singapore client lines to step in or coach
- Education and edtech: the power dialer works through enrollment enquiry lists, and the LeadSquared integration logs each call
- IT services and managed service providers: ServiceNow and Freshservice integrations log support calls against IT tickets
Who CallHippo is for
- Early-stage teams of roughly 1 to 10 users that want to start without a subscription and add paid seats only as reps are hired
- Teams on smaller CRMs such as Insightly, Vtiger, Keap or Bitrix24, which CallHippo connects natively
Who CallHippo is not for
- Teams that want 24/7 AI call answering in the same plan, since CallHippo's Singapore page lists no AI voice agent
- Buyers who need the Singapore number price before signing up, because CallHippo shows number rates only in the dashboard after a KYC check
Pricing
- Basic: free, paying only for numbers and usage
- Starter: $19/user/month
- Professional: $30/user/month
- Ultimate: $42/user/month
- Free 10-day trial on paid plans with no credit card
3. JustCall (4.20/5): best for sales teams that mix SMS outreach with calling

JustCall is the best Singapore virtual number provider for sales and support teams that text customers as often as they call them. Every plan bundles 500 to 1,000 SMS segments with unlimited inbound and outbound minutes, so text follow-ups after missed calls do not need a second tool.
JustCall ranks third because it sells four Singapore number types and pairs voice with SMS on every plan. Two things hold its score down: every plan requires at least two licenses, and Singapore number prices appear only inside the dashboard.
Key features
- Singapore local (+65 6), national (+65 8), mobile and 1800 toll-free numbers
- Unlimited inbound and outbound minutes on the Team plan
- SMS and MMS with 500 segments on Team and 1,000 on Pro and Pro Plus
- Power dialer and bulk SMS campaigns on Pro
- AI call scoring, sentiment analysis and real-time agent assist on Pro Plus
- Unlimited AI transcription minutes on every plan
Integrations
- CRM with call and SMS logging: HubSpot, Salesforce (CTI on Pro), Pipedrive, Zoho CRM and Freshsales, plus Close, Copper, Attio, Kommo, monday.com and Follow Up Boss
- Helpdesk and sales engagement: Zendesk Support, Zoho Desk, Freshdesk, Intercom, Front and Gorgias, plus Outreach, Salesloft, Apollo and Gong
- 70+ native integrations (100+ listed in total), plus Slack, and Zapier, Make and Pipedream for automation
Use cases
- Lead follow-up by text: when a Singapore lead misses a call, a rep sends an SMS from the same +65 number so the conversation continues in writing
- Outbound cadences that combine the power dialer with bulk SMS campaigns, with both calls and texts logged to HubSpot or Pipedrive
- Porting an existing Singapore number into JustCall in 2 to 5 business days with a Letter of Authorization
Industries
- Real estate: the Follow Up Boss integration logs every call and text to the buyer or seller record, alongside SMS viewing reminders
- Financial services: AI call scoring and sentiment analysis help managers review advisor conversations without listening to every recording
- Home and field services: Jobber and ServiceTitan integrations link calls and texts to the right job, so dispatchers see the full customer thread
Who JustCall is for
- Sales teams of roughly 2 to 50 users that already run outreach in Outreach, Salesloft or Apollo and want calls and texts logged there too
- Overseas companies that want a +65 number live quickly, since JustCall states that standard Singapore virtual numbers need no proof of address or local ID
Who JustCall is not for
- Solo founders, because the two-license minimum on every plan makes the real entry price $58 a month
- Teams that want calling inside Microsoft Teams, since JustCall's integration directory does not list Microsoft Teams
Pricing
- Team: $29/user/month billed annually, minimum 2 licenses
- Pro: $49/user/month billed annually, minimum 2 licenses
- Pro Plus: $89/user/month billed annually, minimum 2 licenses
- Business: quote-based, minimum 10 licenses
- Free 14-day trial with no credit card
4. Ringover (3.95/5): best for teams of three or more that want unlimited calls on a bundled number

Ringover is the best Singapore virtual phone option for teams of three or more that want one flat per-user price with unlimited national calls and a shared company number. The entry Talk plan keeps the monthly bill predictable for offices that spend most of the day on local calls.
Ringover ranks fourth because its Singapore page explains every number range (+65 3 for business IP telephony, +65 6 for landlines and +65 8 or 9 for mobile) and it offers 100+ CRM and ATS integrations. Its score is held back because each self-serve plan requires at least three users. Businesses using CRM platforms can explore telephony integration with CRM to understand how phone systems connect with customer records and streamline sales communication.
Key features
- One local or toll-free company number on Talk; one number per user on Business
- Unlimited national calls on Talk; unlimited calls to 90 destinations on Business
- Custom greetings, call forwarding and IVR
- Call recording on every plan
- Power dialer for outbound calling
- Web and mobile apps
Integrations
- CRM with call logging: Salesforce, HubSpot, Pipedrive, Zoho, Microsoft Dynamics, Odoo and Close
- Helpdesk: Zendesk, Zoho Desk, Freshdesk, Intercom, Front and Gorgias, so support calls land on the right ticket
- Recruiting: Bullhorn, JobAdder, Loxo, Crelate, Avionté and Zoho Recruit; 100+ CRM and ATS integrations in total
Use cases
- Giving each rep a personal +65 landline or mobile line for $10 per user per month when clients need a direct number

Industries
- Real estate agencies: one shared company number on listings, with IVR routing buyers to the agent handling each property
- Agencies and consultancies: custom greetings and IVR route client enquiries to the right consultant
- Support-led SaaS and e-commerce: Zendesk, Intercom and Gorgias integrations tie Singapore customer calls to existing tickets
Who Ringover is for
- Singapore-based offices of roughly 3 to 50 users that make many local calls and want a predictable monthly bill
- Recruitment agencies running on Bullhorn, JobAdder or Loxo that want candidate calls logged automatically
Who Ringover is not for
- Solo founders and two-person teams, since the three-user minimum makes the smallest bill $57 a month on Talk
- Teams that want an AI voice agent answering calls, which Ringover's Singapore page does not list
Pricing
- Talk: $19/user/month, minimum 3 users, 1 shared company number
- Business: $49/user/month, minimum 3 users, 1 number per user
- Unified: $69/user/month, minimum 3 users
- Enterprise: custom pricing, minimum 50 users
- Extra landline or mobile line: $10/user/month
5. RingCentral (3.90/5): best for offices that want calling, video and messaging in one suite

RingCentral is the best Singapore virtual phone option for SMBs that want the phone line inside a wider unified communications suite. One app covers business calls, video meetings and team messaging, which suits hybrid offices that would otherwise pay for a separate meeting tool. RingCentral operates in Singapore under local terms of service.
RingCentral ranks fifth because it scores 5 on both features and integrations, with 500+ apps in its App Gallery and SSO for admin control, but it publishes less Singapore number detail than the four providers above it.
Key features
- Business phone, video meetings and team messaging in one app
- Auto-attendant, call queues and multi-level call routing
- Call recording and call analytics
- SSO and SAML for centralized admin control
- AI receptionist add-on with about 100 minutes included
- Desktop, mobile and web apps
Integrations
- CRM on the Advanced plan: Salesforce and HubSpot, with click-to-dial, automatic call logging and contact sync
- Collaboration on the Core plan: Microsoft Teams (calls, texts and fax from inside Teams), Google Workspace (calling from Gmail, calendar and contact sync) and Slack
- 500+ integrations in the RingCentral App Gallery, plus open APIs for custom builds
Use cases
- Replacing an on-premise PBX at a Singapore office with one cloud system for calls, video meetings and messaging
- Hybrid teams moving a phone call into a video meeting without switching apps
- Answering the main Singapore line during lunch hours and after work with the AI receptionist add-on
Industries
- Professional and legal services: call recordings support file notes when advice is given by phone
- Healthcare: SSO and central admin control over who can access calls, messages and recordings
- Manufacturing and logistics: one phone system covers offices, warehouses and sites, so a Singapore distribution hub and regional branches share extensions and routing
Who RingCentral is for
- Established SMBs with 10 or more staff and an IT lead that want one vendor for phone, video and messaging
- Microsoft 365 and Google Workspace businesses that want calling inside the tools staff already use every day
Who RingCentral is not for
- One- or two-person businesses that only need a +65 number, since they would pay for video and messaging they will not use
- Buyers who want the advertised price to be the final price, because taxes and regulatory fees are added on invoices
Pricing
- Core: $20/user/month billed annually
- Advanced: $25/user/month billed annually
- Ultra: $35/user/month billed annually
- AI receptionist: from about $39/month with roughly 100 minutes, then about $0.50 per extra minute
- Taxes and regulatory fees added on top of plan prices
6. Zadarma (3.80/5): best for pay-as-you-go users who want a cheap +65 number with a free PBX

Zadarma is the best Singapore virtual number provider for cost-conscious SMBs that want no per-user subscription. Every number comes with a free cloud PBX, including voice greetings, call recording and the built-in Teamsale CRM, so a micro-business pays only for the number and call minutes.
Zadarma ranks sixth because it publishes prices for three Singapore number types and costs the least to run, but its PBX needs manual setup and it offers no AI features.
Key features
- +65 3 national, +65 8 mobile and 800 toll-free numbers
- Free cloud PBX with IVR and voice greetings
- Free call recording and the built-in Teamsale CRM
- Free incoming calls on +65 3 numbers
- Call forwarding to a phone, SIP server or office PBX
- 2 concurrent incoming lines per number
Integrations

- Automation: 9,000+ apps through Zapier, including Pipedrive, Odoo CRM and Airtable
- Telephony: SIP connection to an existing office PBX, desk phones and softphones
Use cases

- Receiving Singapore SMS verification codes on a +65 8 number when registering on platforms that require a local mobile number
- A low-volume 800 toll-free enquiry line at $19.20 a month
Industries
- Consultancies serving Singapore clients from abroad: the free Teamsale CRM records who called without paying for a separate CRM
- IT and telecom resellers: SIP access and an API let resellers build custom call setups for clients and attach Singapore numbers to them
- E-commerce startups on HubSpot: the certified HubSpot app logs customer calls without a paid phone plan
Who Zadarma is for
- Technically comfortable founders and micro-teams of roughly 1 to 5 users that want the lowest fixed cost and are happy to configure a PBX themselves
- Businesses with an existing SIP-based PBX that only need a Singapore number added to it
Who Zadarma is not for
- Teams that want a Singapore mobile number for voice calls, because Zadarma's +65 8 numbers receive SMS only
- Individuals without a registered company who want a +65 8 number, because Zadarma connects Singapore mobile numbers only for business clients with a company registration certificate and a utility bill from the last six months
Pricing
- +65 3 national: $7.50/month, no connection fee
- +65 8 mobile (SMS only): $39.60/month, no connection fee
- 800 toll-free: $19.20/month plus a $16 connection fee
- Lower monthly rates when paid yearly
- Outbound calls billed per minute
7. Aircall (3.65/5): best for multi-country teams that want support from a Singapore office

Aircall is the best Singapore virtual phone option for SMBs that already run teams across several countries and want Singapore added to the same system. Aircall creates numbers in 100+ countries from one account, and new numbers, users and routing rules can be added without a support ticket.
Aircall ranks seventh only because of its pricing. Aircall scores 5 on features and integrations, but billing per license with a three-license minimum pulls its pricing score down to 2.
Key features
- Numbers in 100+ countries, added on the fly
- Custom call routing, call transfers and a team availability view
- Live and post-call tagging and note-taking
- Call coaching and real-time team metrics
- AI Assist for call summaries ($9/license/month on Essentials, included on Professional)
- AI Voice Agent with 50 free minutes per account per month
Integrations

- 100+ integrations in total, including Slack and Zapier
Use cases
- Coaching new Singapore hires through live and post-call tagging, call notes and call coaching
- Covering overflow and after-hours calls with the AI Voice Agent, using the 50 free minutes each month before buying a bundle
- Routing Singapore callers by team availability, so calls reach whoever is free instead of ringing out
Industries
- SaaS and technology: sales and support teams selling across several APAC markets keep every Singapore call logged in Salesforce or HubSpot next to deals and tickets
- E-commerce: the Shopify integration shows store and order context during support calls, so agents can answer delivery questions from Singapore shoppers on the first call
- Travel and hospitality: booking teams manage local numbers for Singapore and other markets from one account, with routing that follows each office's business hours
Who Aircall is for
- Teams of roughly 3 to 50 users that want same-day onboarding and support in Singapore business hours, delivered from Aircall's Singapore and Australia offices
- Companies that prioritize reliability, given Aircall's stated 99.95% uptime (about 4.4 hours of downtime a year) with multiple voice carriers and dynamic switching
Who Aircall is not for
- Solo founders and two-person teams, since the three-license minimum sets a $90 monthly floor
- Buyers who need Singapore number types and prices confirmed before signing up, since Aircall's Singapore page does not list them
Pricing
- Essentials: $30/license/month annual, $40 monthly, minimum 3 licenses
- Professional: $50/license/month annual, $70 monthly, minimum 3 licenses
- Custom: quote-based, minimum 25 licenses
- Numbers: 1 included per plan; extra numbers $6/month
- AI Voice Agent bundles: $175 for 500 minutes; free 7-day trial
8. Sonetel (3.30/5): best for solo founders and overseas companies that need a low-cost +65 presence

Sonetel is the best Singapore virtual number option for solo founders and overseas companies that want the lowest monthly cost. A +65 3 city number starts at $5.99 a month and rings through Sonetel's free Android, iOS and web apps, so no extra hardware or phone plan is needed.
Sonetel ranks eighth because it scores 5 on pricing but sells only two Singapore number types and connects to CRMs only through Zapier.
Key features
- +65 3 city numbers and 800 toll-free numbers
- Call forwarding at local call rates
- Voice response and call recording on paid plans
- AI call summaries and call scoring on Premium and Business
- AI voicemail summaries and drafted follow-up emails
- Free Android, iOS and web apps
Integrations
- CRM through Zapier: HubSpot and Zoho CRM can receive call events, as part of the 9,000+ apps Sonetel connects with on Zapier
- AI and messaging through Zapier: OpenAI (ChatGPT), WhatsApp Notifications and ClickSend SMS
- Telephony: SIP support for desk phones and softphones
Use cases
- Putting a +65 3 number on a website and forwarding calls to a mobile anywhere in the world at local call rates
- A solo consultant with no CRM using AI call summaries and drafted follow-up emails on the Premium plan to keep track of client calls
- A low-volume 800 toll-free line for enquiries, with the owner paying a per-minute fee on received calls
Industries
- Consulting and freelancing: Singapore clients call a local number that rings on the consultant's own mobile, wherever the consultant is
- Small exporters and trading companies: a Singapore number on quotes and invoices gives buyers and partners a local contact without renting an office
- Education and travel agencies: Premium includes a free number for each team member, so every counsellor or agent gets a direct line
Who Sonetel is for
- Solo founders, freelancers and overseas companies of roughly 1 to 5 users that want a Singapore presence for under $10 a month
- Personal and pre-incorporation buyers, because Sonetel accepts a passport or ID number instead of a Singapore business registration
Who Sonetel is not for
- Teams that need SMS on their Singapore number, since Sonetel's Singapore numbers do not support SMS or SMS-to-email
- Businesses that may want to move the number later, because Sonetel does not support porting for Singapore numbers
Pricing
- Singapore +65 3 number: from $5.99/month
- Premium: $9.95/user/month billed annually
- Business: $29.95/user/month
- Premium and Business include a free number for each team member
- Monthly, yearly or three-year terms, with lower monthly cost on longer terms
9. FreJun (3.20/5): best for outbound sales reps who dial straight from their CRM

FreJun is the best Singapore virtual number option for outbound sales teams that work inside a CRM and want calls placed, logged and summarized without switching tabs. Four auto dialer modes support high daily call volumes, and a Singapore virtual number is included in every plan.
FreJun ranks ninth because it is a focused outbound dialer rather than a full phone system, which limits its scores on Singapore coverage and inbound features.
Key features

Which Singapore virtual number type does an SMB need?
Most SMBs need a +65 3 national number, because it is the cheapest Singapore number type, supports inbound and outbound calls, and activates as soon as documents are approved. The table shows what each type can do and which providers in this comparison sell it.
| Number type | Calls and SMS | Documents and setup | Sold by (price where public) |
| +65 3 national | Inbound and outbound calls; usually no SMS | Company details; live after approval | Sonetel ($5.99), CloudTalk ($6), Zadarma ($7.50), Ringover |
| +65 6 landline | Inbound and outbound calls; no SMS | ACRA BIZfile extract; 10 to 15 business days | CloudTalk ($15 + $95 setup), JustCall, Ringover |
| 800 or 1800 toll-free | Inbound calls only; free for the caller | Usually no documents | CloudTalk ($15 + $15 setup), Zadarma ($19.20 + $16 setup), Sonetel, JustCall, CallHippo |
| +65 8 or 9 mobile | Often SMS only, with no voice | Company registration and address proof | Zadarma ($39.60), CloudTalk ($110), JustCall, CallHippo, Ringover |
An SMB that wants callers to see a familiar local number on outbound calls should choose +65 3 or +65 6. A +65 8 number only makes sense when the main job is receiving SMS, such as OTP codes.
How do you choose a Singapore virtual phone number provider?
Choosing a Singapore virtual phone number provider comes down to six checks that pricing pages rarely spell out:
- IMDA registration: Singapore numbers must be registered to an identifiable subscriber, and unregistered numbers can be blocked. Ask the provider whether its +65 numbers are IMDA-registered before moving customers onto them.
- Company email: some providers reject free email addresses such as Gmail during verification, so sign up with a company domain.
- PDPA and DNC rules: marketing calls and SMS must be checked against Singapore's Do Not Call Registry, and personal data collected on calls falls under the PDPA.
- Concurrent calls: check how many calls one number can carry at once. Zadarma includes 2 incoming lines per number, while CloudTalk lets several agents answer the same number at the same time.
- Per-minute charges: number rental rarely includes outbound minutes, some providers charge $0.01 to $0.04 per minute for inbound calls, and toll-free owners pay for every received minute.
- Caller ID display: some carriers apply anti-spoofing filters, so test how the +65 number shows on a Singapore mobile before launching an outbound campaign.
Conclusion: which Singapore virtual phone number provider should an SMB choose?
The right Singapore virtual phone number provider depends mostly on team size, because seat minimums change the real price more than plan rates do. A solo founder pays the least with Sonetel at $9.95 a month including the number, or Zadarma at $7.50 plus call minutes.
At two users, FreJun ($28.98) and CallHippo ($38 plus the number) are the cheapest dialer options, while Ringover and Aircall still bill for three seats. From three users with both sales and support calls, CloudTalk gives the widest +65 number choice with routing, CRM logging and AI in one plan.
A Singapore virtual phone number costs $5.99 to $7.50 a month on its own for a +65 3 number, but a two-person team usually pays $20 to $90 a month once per-user plan fees are added. Sonetel comes to $19.90 for two users, CloudTalk to $56 and Aircall to $90, before per-minute call charges and taxes.
Most Singapore virtual number providers ask for a company name, a business address and proof of business registration to meet IMDA verification rules. A +65 6 landline needs an ACRA BIZfile extract from the past 12 months, and Zadarma's +65 8 numbers also need a utility bill from the last six months. Sonetel accepts a passport or ID number for personal buyers.
Receiving SMS works on most Singapore virtual mobile numbers, but sending SMS is more restricted. Messages that use a business name as the sender ID must come from a sender ID registered in Singapore's SMS Sender ID Registry, run by SGNIC, and messages from unregistered sender IDs are blocked.
Free Singapore virtual numbers for business are rare. Free temporary +65 numbers online are shared SMS-receiving services, so anyone can read the messages, and virtual numbers in general cannot be used for Singpass, which requires a physical SIM. Paid plans such as Sonetel Premium and Ringover Talk include a number at no extra cost.
Porting an existing Singapore number depends on the provider and usually requires a Letter of Authorization signed by the current number owner. JustCall and CallHippo accept Singapore number porting, with JustCall quoting 2 to 5 business days, while Sonetel and CloudTalk do not currently port Singapore numbers. Moves between two virtual providers are less reliable than moves from a carrier.
