Best Virtual Phone Number Apps for Business (US and International)

The best virtual phone number app depends on where your customers are. For a US-only business, Quo (formerly OpenPhone) or Google Voice covers most needs at $10 to $23 per user per month on annual billing; if you need local numbers in other countries, KrispCall, CloudTalk or CallHippo are built for that; and a small sales team that wants unlimited US and Canada calling plus CRM integrations can start with CallHippo. Whatever you choose, budget for add-ons such as extra numbers, international minutes and US texting registration, which often decide the real monthly cost.

Key Takeaways

• Coverage varies more than tenfold. CallHippo lists numbers in "150+ countries", CloudTalk in "160+", Dialpad in "over 50" and Google Voice for Workspace in 14 (CallHippo, CloudTalk pricing, Dialpad pricing, Google Workspace, retrieved 2026-10-16).
• Free Google Voice is US-only. Google says Voice "only works for personal Google Accounts in the US and Google Workspace accounts in select markets" (App Store listing, retrieved 2026-10-16).
• US texting has a registration fee. Quo lists Campaign Registry registration at $19.50 one-time plus $1.50 to $3 a month for business texting (Quo pricing, retrieved 2026-10-16).
• Call quality depends on the network as much as the app. RingCentral recommends 90 Kbps or more per voice line and says latency above 300 ms is "generally unacceptable" (RingCentral QoS, retrieved 2026-10-16).
• Entry prices hide per-minute billing. KrispCall's Essential plan is about $12 per user per month on annual billing, but calls come from a separate credit balance, per a June 2026 review (Hackceleration, retrieved 2026-10-16).

Do you need a virtual number?

A virtual phone number is a number that is not tied to one SIM card or desk phone. Calls and texts go through an app on your phone or computer, so you can keep your personal mobile private, share one number across a team, and get a local number in a city or country where you have no office.

You need one if any of these are true:

• You give your personal mobile to customers and want to stop.
• More than one person needs to answer the same number.
• You sell into another country and want customers to call a local number.
• You want call recording, business hours, voicemail transcription or CRM logging.

You may not need a paid app if you are a solo founder in the US with modest call volume. Free personal Google Voice gives you a second number for calls and texts. The catch: it is US-only, personal-account only, and it is not designed for a team.

Number availability by country

The first filter is whether a provider can give you a number where your customers are. Vendor claims as listed on 2026-10-16:

"Countries" is not the whole story. Before you buy, check three things on the provider's coverage page for each country you need:

1. Number type. Local, mobile, national and toll-free numbers have different availability. Some countries offer only one type.
2. Address or ID requirements. Some countries require proof of a local address or business registration before a number is issued, which can delay setup by days.
3. SMS support. Voice-capable numbers in some countries cannot send or receive texts.

KrispCall: best for global numbers

KrispCall is a cloud phone system aimed at small sales and support teams that need numbers in several countries at a low base price. KrispCall's own pricing page blocked automated access when we researched this guide, so the figures below come from Hackceleration's review, updated June 2026 (Hackceleration, retrieved 2026-10-16):

The review says extra numbers cost about $5 to $20 a month depending on type and country, US and Canada calls cost about $0.01 to $0.05 a minute from a separate credit balance, and numbers are available in 100+ countries.

Best for: small teams that need local numbers in several countries and do not make enough calls to justify unlimited-minute plans. Not for: teams that make many outbound calls a day, where per-minute billing can overtake a flat unlimited plan. Confirm current prices on KrispCall's site before buying.

CallHippo: best for small sales teams

CallHippo bundles North American calling minutes into each plan, which suits teams that spend the day on outbound calls. It lists numbers in 150+ countries, a 10-day free trial with no credit card, and integrations with Salesforce, HubSpot, Slack and Zendesk (CallHippo, retrieved 2026-10-16).

Core phone plans in US dollars, as shown on 2026-10-16 (CallHippo pricing, retrieved 2026-10-16):

The pricing page mixed US dollar and rupee figures for other plans and add-ons when we read it, and annual billing is advertised as "Save 3 Months' Cost", so request a written quote in your currency.

Best for: small sales teams that call the US and Canada heavily and want minutes included. Not for: a solo user who mostly needs a second number for inbound calls; a cheaper plan elsewhere does that.

CloudTalk: best for wide coverage with a built-in dialer

CloudTalk lists local numbers in 160+ countries, the widest coverage claim in this roundup, along with unlimited inbound and internal calls on all plans (CloudTalk pricing, retrieved 2026-10-16). Prices are shown in euros, excluding VAT:

Add-ons include a Power Dialer at €15 per user per month and a Parallel Dialer at €39, both on annual billing. There is a 14-day trial with no credit card.

Best for: sales and support teams in Europe or selling into many countries who want dialers and analytics on top of numbers. Not for: a solo founder who needs one US number; Quo or Google Voice is simpler and cheaper.

OpenPhone (Quo): best US-only

Quo, formerly OpenPhone, is the most straightforward option for US and Canadian businesses. Every plan includes one local or toll-free number per user and unlimited calling and texting within the US and Canada, under a fair usage policy (Quo pricing, retrieved 2026-10-16):

Extra numbers are $5 a month each. International calls and texts are billed per minute or message from credits. Texting requires Campaign Registry registration at $19.50 one-time plus $1.50 to $3 a month. The trial lasts 7 days.

Best for: US and Canadian small businesses that want unlimited domestic calls and texts on one business number per user. Not for: anyone who needs a number outside the US and Canada.

Google Voice: the free baseline

Personal Google Voice is free and gives you a second US number for calls and texts, but it requires an existing mobile number and works only for personal Google Accounts in the US.

For businesses, Google sells Voice plans through Google Workspace, as listed on 2026-10-16 (Google Workspace, retrieved 2026-10-16):

Best for: teams already on Google Workspace who want a simple business number in one of the 14 supported countries. Not for: sales teams that need dialers, CRM call logging and broad international coverage.

RingCentral and Grasshopper

RingCentral

RingCentral is the established full business phone system, with video, contact center and AI add-ons. Its plans page did not show plan prices when we read it, only "Save up to 33% by paying annually" and a 14-day trial. Ringly's 2026 pricing breakdown lists RingEX Core at $20, Advanced at $25 and Ultra at $35 per user per month on annual billing, or $30, $35 and $45 monthly (Ringly, retrieved 2026-10-16). Add-ons on RingCentral's own page include a Business SMS Booster at $25 and an AI Receptionist from $39.

Best for: larger companies that want one vendor for phones, meetings and a contact center. Not for: a two-person startup that only needs numbers.

Grasshopper

Grasshopper prices per account, not per user. Its own blog lists True Solo at $14 a month (1 number, 1 user), Solo Plus at $25 (1 number, unlimited users) and Small Business at $55 (4 numbers, unlimited users), with unlimited minutes in the US and Canada (Grasshopper, retrieved 2026-10-16). Its pricing page confirms the $14 starting price and a 7-day free trial. Third-party sources treat these as annual-billing prices.

Best for: small US businesses where several people share one main number. Not for: international numbers or heavy outbound calling.

Dialpad

Dialpad is another full system to compare, at $15 per user per month for Standard and $25 for Pro on yearly billing, with numbers in over 50 countries and a 14-day trial (Dialpad pricing, retrieved 2026-10-16).

Real monthly cost with add-ons

List prices are per user, but your bill includes extras. The table below prices one scenario: 3 users, US numbers, on annual billing, from the list prices above. It is arithmetic on published prices, not a quote, and excludes taxes and usage charges.

To find your real cost, list every country where you need a number, estimate monthly outbound minutes per user, and decide whether you need texting. Then price two or three apps with those inputs.

Check call quality on mobile data yourself

Call quality depends on the connection, so the only meaningful check is on your own network and phones. During each free trial:

1. Install the mobile app on two phones and make five-minute calls over mobile data, not Wi-Fi, from places where you actually work.
2. Run a speed test at the same spot. RingCentral recommends at least 90 Kbps of dedicated bandwidth per voice line, treats latency up to 150 ms as generally acceptable, and warns that jitter above 50 ms degrades voice quality (RingCentral QoS, retrieved 2026-10-16).
3. Call a landline and a mobile in each country you serve, and note echo, delay and dropped words.
4. Test a handoff from Wi-Fi to mobile data mid-call by walking out of the office.

If quality is poor on all apps at a location, the network is the problem, not the provider.

Frequently Asked Questions

What is the best free virtual phone number app?

Google Voice is the standard free option, giving you a second US number for calls and texts. It works only for personal Google Accounts in the US and requires an existing mobile number. Business features such as shared numbers and call routing need a paid plan from Google Workspace or another provider.

Can I get a virtual phone number in another country?

Yes. CloudTalk lists numbers in 160+ countries, CallHippo in 150+ and KrispCall in 100+, according to the vendors and a June 2026 review. Availability depends on number type, and some countries require proof of a local address or business before issuing a number.

Do virtual phone numbers work for texting?

Most do, with limits. In the US, business texting from apps requires registration with The Campaign Registry; Quo lists a $19.50 one-time fee plus $1.50 to $3 a month. Some international numbers support voice only, so check SMS support per country before buying.

How much does a business virtual phone number cost?

On annual billing, entry plans run from about $10 per user per month (Google Voice Starter) to $15 (Quo Starter, Dialpad Standard) and $18 (CallHippo Starter), as listed on 2026-10-16. Add extra numbers, international minutes and texting fees to find your real monthly cost.

Can I keep my existing number?

Usually, yes. Most providers support number porting, including Quo, which lets you bring a ported number as your included number, and CloudTalk, which supports porting in many countries. Porting rules vary by country and carrier, so start the transfer before you cancel your old service.
