Best International Calling Apps in 2026: 7 Picks Compared on Rates and Features

If you only need to talk to people who also have a smartphone, the best app for international calls in my view is one of the free internet-based ones, and the cost is just your data or Wi-Fi. If you need to reach a landline or a basic phone in another country, or you want a business number that works across borders, you move into paid territory with per-minute rates, credits or subscriptions. This guide compares seven picks across those jobs, using only what each company publishes on its own pages as of November 2026. It is part of what I cover at Ecommerce Paradise, where phone costs are one of those small line items that add up when you run a store from abroad or talk to suppliers overseas.

The quick picks: WhatsApp for free app-to-app calls, Signal for free calls with a privacy focus, Rebtel for pay-as-you-go or flat-rate calls to phone numbers, Google Fi for a phone plan that travels, Quo and Dialpad for business numbers with international calling as an add-on or credit-based extra, and Google Voice for a US number you can reach from anywhere with an internet connection. One more thing worth knowing up front: Skype, which used to be the default answer to this question, is retired according to Microsoft’s own support page, so it is not on the list.

Quick comparison table (as of November 2026)

Prices are the figures shown on each company’s official page when I loaded it. Where a figure was not shown, the table says so. Per-minute rates depend on the destination, so the only rate examples here are ones the page itself shows, labeled with the destination.

Pick	Best for	Key price or limit (from the official page)	Reaches landlines and basic phones?	Main watch-out
WhatsApp	Free app-to-app calls	Calls described as free; data charges may apply; group calls up to 32 people	Not described on its page (calls to WhatsApp contacts)	Both sides need the app and a connection
Signal	Free calls with a privacy focus	Free; no long-distance charges per its site	Not described on its page (calls over a data connection)	Group call size and phone-number requirement not shown on the homepage
Rebtel	Calls to phone numbers abroad	Global Unlimited $12/month for 50 countries; India example 2.39 cents per minute on prepaid credits	Yes, mobile and landline	Country list for the flat plan is not shown on the pages I loaded
Google Fi	A phone plan that works abroad	Flexible from $20 plus $10 per GB; cellular calls abroad 20 cents per minute on Flexible or Unlimited Premium	Yes, it is a phone plan	Cheaper tiers limit international use
Quo	A business number for a small team	$15 to $35 per user per month billed annually; international calling is an add-on billed per minute	Yes, by destination rate	Rates vary by carrier within a country
Dialpad	Business calling across many countries	Connect Standard $15 and Pro $25 per user per month (billing basis not shown); 14-day trial	Yes, charged per minute from call credit	Per-country rates not shown on the pages I could load
Google Voice	A US number you keep while traveling	Plans shown at $10, $20 and $30 per user per month (annual or monthly commitment not shown)	Per its page, rates are on a rate card (not shown on the plans page)	International calling inclusion and rates not shown on the plans page

Rankings and “best for” labels in this article are my editorial opinion based on the published terms, not lab tests or hands-on benchmarks. Terms change, so check the provider before you pay for anything.

What happened to Skype

A lot of older “best calling app” lists still start with Skype. According to Microsoft’s support page, Skype was retired on May 5, 2025 for both free and paid users, and people can sign in to Microsoft Teams Free with their Skype credentials to bring chats and contacts across. The same page says new purchases of Skype Credit ended while existing credit can still be used for calling, and it notes that some details on the page carry conflicting dates, so I am only repeating the headline retirement date. If you still have a balance or a Skype number, read Microsoft’s Skype support page directly rather than relying on a roundup.

The practical takeaway: if you used Skype to call landlines abroad, the closest replacements in this article are Rebtel for a calling-focused service, Dialpad or Quo for business use, and Google Voice if you want to keep a US number.

How I chose these seven

I built this list from each company’s published pages rather than from personal testing, and I am not claiming I made calls on any of these services. The criteria were:

• A clear job. Each pick does something different: free app-to-app calling, privacy-first calling, pay-per-minute calls to phone numbers, a travel-friendly phone plan, or a business number.
• Published pricing. I favored services that show real numbers on an official page. Where a page did not show a rate, I say “not shown” and tell you where to look.
• Works across borders. Either the service is internet-based and works anywhere, or the company lists international calling or travel coverage.
• Still operating. That is why Skype is covered above and not ranked.

I looked at Telegram and Viber as well. Telegram’s FAQ says its voice calls are end-to-end encrypted and that group calls can reach 200 participants, but the page I loaded did not say whether calls cost anything. Viber’s homepage describes free calls and messages, but I did not see paid calling rates or details on the pages I could load, so I left it out rather than guess at prices. Talkroute was also on my shortlist, but the pricing page I loaded showed US and Canada calling and no international calling details.

1. WhatsApp: best for free app-to-app calls

Who it fits: Anyone calling family, friends or suppliers who already use WhatsApp. If the person on the other end has the app and a decent connection, this is the zero-subscription route.

Key facts from the official page: The WhatsApp calling page describes voice and video calls as free, with a note that data charges may apply. It says calls use your phone’s internet connection rather than mobile plan minutes, that calls have no time limit, and that group calls support up to 32 people. WhatsApp states that calls are always end-to-end encrypted. That is the company’s own claim, and the page does not offer independent verification. The page lists iOS, Android, web, Mac, iPad and Windows, and says you can link up to four devices, though you still need your primary phone to register the account.

Strengths:

• No per-minute charges and no time cap on calls, per the page.
• Works on phones and computers, so you can call from a laptop while traveling.
• Group calls up to 32 people are handy for small team check-ins.

Limits and watch-outs:

• The page describes calls to WhatsApp contacts and does not describe calling ordinary landlines or mobile numbers, so plan on it being app-to-app.
• “Free” assumes you are on Wi-Fi or have a data plan. Roaming data can still cost you, which is where a travel plan or eSIM matters (more on that below).
• You need a phone to register the account, so it does not solve the “I want a number” problem by itself.

Verdict: The default pick for free international calls to people who already use the app. Ask the other person to install it before you decide on anything paid.

2. Signal: best for free calls with a privacy focus

Who it fits: People who want free international voice and video calls and care about who can listen. It suits conversations with partners, lawyers, accountants or anyone you would rather not run through an ad-funded platform.

Key facts from the official page: The Signal homepage says its voice and video calls carry no long-distance charges and use your phone’s data connection. It describes Signal as free and as an independent nonprofit whose development is supported by grants and donations. Signal states that it uses end-to-end encryption powered by the open-source Signal Protocol and that it cannot read your messages or listen to your calls. Those are the organization’s own claims. The page I loaded did not say whether a phone number is required to register, so check that during setup.

Strengths:

• Free, with no subscription tiers shown on the homepage.
• Privacy is the stated purpose of the project, not an add-on feature.
• Apps are listed for Android, iPhone and iPad, Windows, Mac and Linux.

Limits and watch-outs:

• The homepage does not describe calling ordinary phone numbers, so treat it as an app-to-app option.
• The homepage did not list group call size, so I am not stating one.
• If nobody you call uses it, the privacy benefit is moot. You may need to ask people to install it first.

Verdict: A strong second free option when the other person is willing to install it. Pair it with WhatsApp so you can reach people on whichever app they actually answer.

3. Rebtel: best for calling mobiles and landlines abroad

Who it fits: People who need to dial real phone numbers in another country, such as relatives without smartphones, a supplier’s office line, or a local service provider. It is built around that job.

Key facts from the official pages: The Rebtel homepage shows a Global Unlimited subscription at $12 per month for unlimited calling to 50 countries, mobile and landline, in USD. The homepage does not list which countries. The page I loaded for India describes the same plan as covering India plus 46 other countries, which does not match the homepage count, so confirm the country list before you subscribe. The homepage also shows new-user offers of 20 minutes to Cuba for $5 and 60 minutes to Nigeria for $1, and its meta description mentions a free first call.

For pay-as-you-go, the Rebtel India page shows 2.39 cents per minute to both mobiles and landlines in India, using prepaid credits where $5 buys 209 minutes and $10 buys 418. It also shows India Unlimited plans at $12 for 30 days, $24 for 90 days or $45 for 180 days. The page says “try one week for free,” though which plans it applies to is unclear, and says “cancel anytime” under India Unlimited. Billing increments, such as per-second or per-minute rounding, were not shown. These are India examples only, because rates depend on the destination.

Worked example (my arithmetic on the page’s India rate): One hour is 60 minutes, and 60 x $0.0239 = about $1.43. Four 30-minute calls in a month is 120 minutes, which is 120 x $0.0239 = about $2.87. The $12 India Unlimited plan only wins if you would use more than roughly 502 minutes in 30 days (12 / 0.0239 = about 502). That matches the page’s own credit math of about 41.8 minutes per dollar. Taxes, if any, were not shown.

Strengths:

• Reaches regular phone numbers, mobile and landline, which the free apps do not describe.
• Both pay-as-you-go credits and flat-rate subscriptions are offered, so you can match it to how often you call.
• “Cancel anytime” is shown next to the India Unlimited plans.

Limits and watch-outs:

• Country lists and per-minute rates are destination-specific, and the homepage does not show them. Look up your exact destination first.
• The homepage and India page differ on the flat plan’s country count, as noted above.
• It is a calling service, not a business phone system, so shared inboxes and team features are not the point.

Verdict: The pick when the person you are calling does not use an app. Check your destination’s rate page, then compare credits against the subscription using the arithmetic above.

4. Google Fi: best for a phone plan that travels with you

Who it fits: People who want one phone plan that also covers data and calls when they travel, rather than buying a separate calling app. It is a carrier plan, so it works like a normal phone line.

Key facts from the official pages: The Google Fi plans page lists, as of my load, Unlimited Premium at $65 for one line, Unlimited Standard at $25 for one line (shown as 50% off for 12 months from a regular $50), Unlimited Essentials at $18 for one line (regularly $35, same offer), and Flexible at $20 for one line plus $10 per GB. The 50% offers are marked “Ends 12/1/26” and, per the page, apply to new lines, so that promotion is less than three weeks from this article’s date and may be gone by the time you read this. Monthly prices exclude taxes and government fees, which the page says are normally between 10 and 20 percent.

On travel, the page says Premium and Flexible include international data in 200+ destinations, Standard lists Canada and Mexico only, and Essentials does not list international data. The page does not say how long you can use the service abroad. On calling, Fi’s international rates page says calls from the US to Canada and Mexico are free on Flexible, Standard and Premium, and calls to 50+ countries and territories are free on Premium without naming them in what I loaded. Other destinations are charged per-minute rates that depend on the destination, with no amounts listed on that page. From abroad, cellular calls are 20 cents per minute on Flexible or Premium, Wi-Fi calls to the US, Canada and Mexico are free, and Essentials does not offer international calls while abroad.

Worked example (my arithmetic on the page’s rate): A one-hour cellular call placed from abroad on Flexible or Premium would be 60 x $0.20 = $12.00 before taxes. The same hour over Wi-Fi to the US would be free per the page.

Strengths:

• Data and calls both work abroad on the higher tiers, so it can replace a separate travel SIM on some trips.
• Wi-Fi calls to the US, Canada and Mexico are free, which helps if you live abroad on stable internet.
• Flexible lets a light user pay mostly for the data they use.

Limits and watch-outs:

• The pages I loaded do not say how long you can use it abroad, so check Fi’s terms if you plan a long stay.
• The cheaper tiers limit international use, and Essentials has none.
• The 50% offer on Standard and Essentials is shown ending December 1, 2026, so the regular price is the one to budget around.

Verdict: Look at Google Fi’s current plans if you travel often and want a single phone plan. If you are planning trips rather than a long stay, my guide to travel eSIMs covers the data-only route.

5. Quo: best for a business number with calling add-ons

Who it fits: Small teams and store owners who want a dedicated business line with team features, and occasionally need to call customers or suppliers abroad.

Key facts from the official pages: The Quo pricing page lists three per-user plans in USD. Starter is $19 per month or $15 per month billed annually, Business is $33 monthly or $23 annually, and Scale is $47 monthly or $35 annually. Every plan includes one phone number per user and US and Canada calling and messaging, subject to the fair usage policy. For other countries, per-minute and per-message rates apply as an add-on billed using credits by destination. Additional phone numbers are $5 per month each. Taxes and fees are added at checkout, and the page advertises a 7-day free trial.

The Quo rates page shows example outbound call rates per minute in USD, with the note that rates vary by carrier within each country. Examples shown there are Australia at $0.05 to $0.33, China at $0.40 to $0.41, Germany at $0.03 to $0.48 and France at $0.03 to $0.68. Calls to Canada are listed as included in the subscription. Billing increments and rounding were not shown.

Strengths:

• Business features come in tiers: call recording is manual on Starter and automatic on Business and Scale, and the HubSpot and Salesforce integrations are on Business and Scale, per the pricing page.
• International calling is pay-for-what-you-use rather than a flat surcharge on every seat.
• Published example rates by destination let you check before you commit.

Limits and watch-outs:

• International calls are not included in the plan price, so heavy overseas calling can add up. Check your destination’s rate.
• The wide ranges in the examples show why the carrier matters, so check the rate for your real destination numbers.
• Messaging registration carries a $19.50 one-time carrier review fee plus a monthly messaging fee of $1.50 to $3, per the pricing page, if you plan to text customers.

Verdict: A good fit for a small store team that mostly calls in the US and Canada and only occasionally calls abroad. Try Quo’s current plans and check the rate for your destination before you rely on the international add-on.

6. Dialpad: best for business calling across many countries

Who it fits: Growing teams that want a cloud phone system with local numbers in many countries and the ability to call most of the world.

Key facts from the official pages: The Dialpad pricing page shows Connect Standard at $15 per user per month and Pro at $25, with Enterprise by quote. The page has a monthly and annual toggle, and I could not confirm which billing basis the figures reflect, so treat them as starting points and verify at checkout. A 14-day free trial is advertised, and the page’s FAQ says local numbers are supported in over 50 countries. Dialpad’s international calling page, per its meta description, offers calls to over 190 countries and says its plans all include free unlimited local calling in your country, the US and Canada. That page says your office’s call credit balance is charged when a team member makes international calls or receives calls to the office’s toll-free lines.

Dialpad’s rates page says calling is billed per minute and texting per message, and lists rates by country in several currencies. The country rows did not show on the version I loaded, so I am not giving any per-country rate here. The pricing page FAQ describes Dialpad’s international rates as some of the lowest in the industry. That is the vendor’s claim, which I did not verify.

Strengths:

• Local numbers in 50+ countries is useful if your customers are spread across regions.
• International calling to 190+ countries per the company, drawn from a call credit balance.
• A free trial period is shown, so you can test call quality for your destinations.

Limits and watch-outs:

• Billing basis for the plan prices is not clear on the page, so confirm it before budgeting.
• International calls draw from the office’s call credit balance rather than being covered by the plan, per the international calling page.
• Regional pricing may differ, and Enterprise pricing is by contacting sales.

Verdict: Worth a look if you need business numbers in several countries. Start from Dialpad’s trial and check rates for the countries you actually use.

7. Google Voice: best for keeping a US number you can use anywhere

Who it fits: People who want a US phone number that rings on a phone or in a browser, including while they live or travel abroad. It pairs well with a free app for calling friends and a paid option for landlines.

Key facts from the official pages: The Google Voice page says a Voice number works on smartphones and the web so you can place and receive calls from anywhere, with voicemail transcription, call forwarding to any device and spam blocking. The Google Workspace Voice page lists paid per-user plans in USD, shown per user per month: Starter at $10 (standalone, for one user, “available in the US”), Standard at $20 and Premier at $30. A Starter option added to a Workspace plan covers up to 10 users in 14 countries, which the page does not list. The page does not state whether international calling is included and points to the Voice rate card for calling rates. It also mentions a basic no-cost plan without giving details, and I could not load Google’s international rate pages.

Strengths:

• A US number that works on the web and phone, per Google.
• Call forwarding and voicemail transcription help when you are in a different time zone.
• Tiered plans let a solo user start small and a team add features.

Limits and watch-outs:

• The standalone Starter plan is shown as available in the US, so check availability for your country before relying on it.
• International calling inclusion and rates are not shown on the plans page.
• Whether the prices assume a monthly or annual commitment was not shown on the page I loaded.

Verdict: A reasonable way to keep a US number while abroad, as long as you confirm its availability and international rates before relying on it. My guide to keeping a US phone number while living abroad walks through the order of steps.

How to choose the right calling app

Start with who you are calling, because that decides everything else. If the other person has a smartphone and uses WhatsApp or Signal, you are done and the cost is data. If they have a landline or an older phone, you need a service that dials real numbers, which means Rebtel, a business system or a phone plan.

Next, decide whether you need a number of your own. A free app uses your existing phone number or account, but a business line gives you a number customers can call back, shared access and voicemail. Quo, Dialpad and Google Voice are built around that. Then look at volume: a few calls a month fit pay-as-you-go credits, while hours a week might justify a flat plan.

Finally, think about connection quality. Every internet-based option depends on your connection, so a good Wi-Fi network or a local eSIM matters as much as the app. If you need data for the trip itself, my best eSIM for Europe comparison shows what that costs. Choosing a plan for a parent who is not tech-savvy is a different problem, and I cover it in my guide to cell phone plans for seniors.

Which to pick if…

If you mostly call family on smartphones, use WhatsApp, and install Signal as a backup. If you call a relative’s landline in a specific country every week, check Rebtel’s rate for that country and compare credits with the subscription. If you run a small store and want a business line with team features, look at Quo first and Dialpad if you need local numbers in many countries.

If you are a digital nomad who wants a US number for banks and verification codes, Google Voice is the one to investigate, with a travel phone plan or eSIM for data. If you travel a few weeks a year and want one plan for everything, Google Fi is the closest to that. These are my opinions based on the published terms, so check the rates for your own countries before you commit.

Mistakes to avoid

• Assuming “free” means free everywhere. Free app calls still use data, and roaming data can be expensive. Use Wi-Fi or a local data plan.
• Not checking the destination rate. Per-minute prices vary by country and by carrier, as Quo’s published ranges show. Look up your exact destination before topping up.
• Ignoring billing basis. Several pricing pages show annual figures next to monthly ones. Confirm which one you are paying.
• Relying on one app. If a supplier or relative does not answer on your app, you lose the call. Keep two options.
• Forgetting verification codes. If you move abroad, your bank or marketplace may still text a US number, so keep that line active until you have updated those accounts.
• Using a retired service. Skype is retired per Microsoft, so do not build a workflow around it.

Why this matters when you run a store from anywhere

Phone costs rarely get the attention that software and ad spend do, but they are real business expenses once you talk to customers, carriers and suppliers in other time zones. If you are working through what high-ticket dropshipping actually involves, you will find that in my view deals on bigger-ticket items tend to involve more calls and back-and-forth than low-ticket ones. A reliable line to a supplier’s sales rep can save days, and a calling app that works over Wi-Fi can keep the per-minute cost at zero, apart from your data.

When you start vetting overseas partners, my guide on how to find suppliers for high-ticket dropshipping shows where calls and messages fit in the process. Check which app a supplier actually uses before you buy a plan. It also helps to list phone and software costs as part of your setup when you work through business formation for high-ticket dropshipping, because a separate business line keeps your records cleaner than a personal one.

If you are still choosing a product direction, the high-ticket niches list is a good place to look before you sign up for any tools.

Frequently asked questions

What is the best app for international calls?
It depends on who you are calling. For people who use the same app, WhatsApp and Signal both describe their calls as free over an internet connection, with only data costs. For regular phone numbers, a calling service such as Rebtel, a business system such as Quo or Dialpad, or a phone plan such as Google Fi is needed, and each charges by minute, credit or subscription.

Are WhatsApp calls really free internationally?
WhatsApp’s calling page describes calls as free and says they use your phone’s internet connection instead of plan minutes. It also notes data charges may apply, so on a mobile connection abroad you may still pay your carrier for data. Wi-Fi avoids that.

Can I call a landline from an app?
WhatsApp’s and Signal’s pages describe calls over an internet connection and do not describe calling landlines, so treat them as app-to-app. Rebtel, Quo, Dialpad and Google Fi all offer ways to call regular phone numbers, with rates by destination. Check each service’s rate for your country before you pay, since rates vary by destination.

Is Skype still a good option?
According to Microsoft’s support page, Skype was retired on May 5, 2025 for free and paid users, with Teams Free offered for those who want to carry over chats and contacts. If you have leftover Skype Credit, read Microsoft’s page for what is still supported.

What is the cheapest way to call a number abroad?
I cannot name a single cheapest option, because rates depend on the destination, the carrier and how much you call. For a specific country, compare per-minute credits against any flat plan, as in the India arithmetic above. This is general information, not financial advice, and terms change, so check the provider.
