The Best Apps for International Calls in 2026
The best app for international calls depends on one question that splits this whole category in two: does the person you're calling have a smartphone with apps, or are you dialing a real phone number abroad? If they're on WhatsApp or FaceTime, international calling is free, unlimited, and solved, because the call never touches a phone network and borders don't exist for it. If you're dialing a landline in Lagos, a mobile in Manila, or a business in Berlin, someone has to pay a phone network to complete that call, and the game becomes finding the app with honest rates to your specific country. Most bad advice in this category comes from mixing the two cases up, so this guide keeps them separate: the free half first, the real-numbers half second.
For years the reflex answer to both halves was Skype. Microsoft retired it in May 2025, taking its calling credit with it, which is why every option below has absorbed a share of its former users.
How we picked the best apps for international calls
Every app-to-app entry had to be free, encrypted or close to it, and common enough in its regions that the person you're calling plausibly already has it, since an app your relatives won't install is worthless whatever its quality. Every real-number entry had to publish its rates openly, work without a contract, and be a going concern in 2026 with the vendor actively maintaining it; international calling has a long tail of zombie apps still ranking in app stores on reviews from a decade ago, and none of them made the cut. Exact prices aren't quoted anywhere here, because per-country rates shift constantly and any number printed today misleads you next quarter. Compare rates for your destination on the provider's own page before buying credit.
Calling people abroad free, app to app
1. WhatsApp
The default, and deservedly. WhatsApp's install base is so dominant across Europe, Latin America, Africa, the Middle East, and South Asia that for most country pairs the person you're calling is already on it. Voice and video are free, unlimited, and end-to-end encrypted, calls hold up well on weak connections, and the desktop apps mean the call doesn't have to happen on your phone. Its only real limitation is the premise: both sides need the app.
Where it wins: the largest install base on earth, reliable quality on poor networks, free forever with no meter running.
Where it hurts: can't reach any real phone number, and it's banned or degraded in a few countries, notably China and the UAE, where calls may not connect.
Pricing: free.
Best for: almost everyone's first choice for calling family and friends abroad.
2. Telegram
Telegram's calls are free and its audio quality is excellent, with the app's real advantage being reach where WhatsApp is weak: it's a primary messenger across much of Eastern Europe, Central Asia, and Iran. It's also the lightest of these apps on old phones and slow connections. Encryption for calls is Telegram's own protocol rather than the widely audited standard WhatsApp uses, which most callers won't care about but is worth knowing.
Where it wins: strong install base in regions WhatsApp doesn't dominate, lightweight, good call quality.
Where it hurts: no real-number calling, and in WhatsApp-dominant countries you'll be asking people to install something new.
Pricing: free.
Best for: calling contacts in Telegram-strong regions.
3. Viber
Viber straddles both halves of this guide, which is its pitch. App-to-app calls are free and encrypted, with an install base concentrated in Eastern Europe, the Balkans, the Middle East, and parts of Asia. Viber Out then adds pay-per-minute calling to any real phone number, at rates that are competitive for exactly the destinations where Viber is popular. One app for free calls to your cousin and paid calls to her landline-only parents is a genuinely convenient combination.
Where it wins: free app-to-app plus real-number calling in one app, strong where its user base lives.
Where it hurts: thin adoption in North America and Western Europe, and heavy in-app promotion of stickers and ads.
Pricing: free app-to-app; Viber Out is per-minute credit or destination bundles.
Best for: callers whose contacts are in Viber-strong regions, especially with landlines in the mix.
4. FaceTime
If both ends have Apple devices, FaceTime is the highest-quality option here, free, encrypted, and already installed. Android and Windows users can now join FaceTime calls from a browser link, but only an Apple user can start a call, which keeps it a supplement rather than a universal answer.
Where it wins: best-in-class quality, zero setup on Apple devices, encrypted by default.
Where it hurts: call initiation is Apple-only, no real-number calling internationally, and the browser-link workaround is clunky for regular use.
Pricing: free.
Best for: international calls between iPhone and Mac households.
Calling real foreign phone numbers
5. Google Voice
Beyond its free US and Canada calling, Google Voice quietly offers per-minute international rates that are among the lowest from any mainstream app, billed against credit you top up. For US users who already have it, calling abroad may need no new app at all: the dialer, your credit, and the country code are the whole workflow, from the phone app or a browser tab. The catch remains signup, which requires a US presence.
Where it wins: low published rates, works from a browser, no new account if you already use it, a real inbound US number included.
Where it hurts: US-only signup, credit-based rather than subscription pricing suits light callers better than heavy ones, and rates to a few destinations are beaten by specialists.
Pricing: free US/Canada calling; international metered per minute against prepaid credit.
Best for: US users who call abroad occasionally and want one fewer app.
6. Rebtel
Rebtel specializes in exactly one thing: cheap calls from immigrants and diaspora communities to their home countries, with unlimited-calling subscriptions per destination rather than a per-minute meter. Its distinctive trick is routing calls over local phone lines rather than pure data where that helps, which keeps quality steady on bad connections. If you call one or two countries constantly, a flat subscription beats every per-minute model in both cost and peace of mind.
Where it wins: flat-rate unlimited plans per country, quality that survives poor data connections, built for high-volume calling home.
Where it hurts: subscription pricing is poor value for occasional callers, and coverage strength varies by corridor, with its best deals on major diaspora routes.
Pricing: monthly subscriptions per destination, plus pay-per-minute credit as an alternative.
Best for: people who call the same country several times a week.
7. Talk360
Talk360 targets calls to destinations the big apps price badly, with particular strength into Africa, and sells simple prepaid credit with rates shown before you dial. Its other differentiator is payments: it accepts a wide range of local payment methods, which matters for users without international credit cards. The app is plain and does one job.
Where it wins: competitive rates into Africa and other underserved destinations, transparent prepaid credit, local payment options.
Where it hurts: no free calling of any kind, no inbound number, and rates to mainstream destinations are unremarkable.
Pricing: prepaid per-minute credit.
Best for: calling real numbers in Africa and other regions the big apps neglect.
8. Sonetel
Sonetel comes at international calling from the business side: its core product is local phone numbers in dozens of countries, so a customer in another country can dial a local number and reach you, with cheap outbound calling attached. For a small business serving customers abroad, or anyone who needs to receive international calls rather than only place them, it solves a problem none of the consumer apps touch.
Where it wins: inbound local numbers in many countries, cheap outbound rates, useful web-based calling.
Where it hurts: the product is aimed at businesses, so the interface and onboarding feel like it, and casual callers are better served elsewhere.
Pricing: small monthly fee per number plus metered calls.
Best for: receiving international calls on local numbers, small businesses abroad.
9. A softphone with a SIP provider
The enthusiast option, and for heavy volume the cheapest: a free softphone like Zoiper or Linphone connected to a SIP provider you choose, paying rates close to wholesale for any destination on earth. You trade convenience for control, since setup means credentials and settings rather than a signup wall, but no consumer app matches the per-minute economics at volume. The VoIP app roundup covers this setup in more detail, and the guide to internet calling explains the protocol underneath it.
Where it wins: the lowest rates available to nearly every destination, numbers in countries no consumer app serves, no lock-in.
Where it hurts: technical setup, provider quality varies, and nothing about it is designed for casual users.
Pricing: free apps; the provider bills per minute, typically prepaid.
Best for: heavy international callers comfortable with configuration.
Check the dialing format before blaming the app
A surprising share of "this app doesn't work" complaints are dialing errors. Every international call to a real number needs the full format: a plus sign or your country's exit code, then the destination country code, then the number with its leading zero usually dropped. Getting this wrong produces silence, wrong-number connections, or error tones that look exactly like an app failure. The how to call guides list the codes and cover per-country quirks and the time zone arithmetic that causes the other class of failed calls: perfectly dialed numbers ringing at 4 a.m. local time, unanswered.

How to actually choose
Ask who you're calling before asking which app. If they have a smartphone, install what they already use, which usually means WhatsApp, and the cost question evaporates. If you're dialing real numbers, match the model to your volume: constant calls to one country point to a Rebtel subscription, occasional calls to Google Voice credit or Viber Out, hard-to-reach destinations to Talk360, and serious volume to a SIP setup. If you need to receive calls from abroad, Sonetel is the only consumer-accessible answer on this list. And if the call needs to happen on a computer rather than a phone, the roundup of apps to call from your computer covers that angle.
Frequently asked questions
What is the best free app for international calls? WhatsApp, for the simple reason that the person you're calling probably has it. Calls are unlimited, encrypted, and identical in cost whether the other person is next door or on another continent, which is to say free. Telegram and FaceTime win in their niches: Telegram where it dominates regionally, FaceTime between Apple devices.
How can I call a foreign landline cheaply? Landlines force you into the paid half of this guide, since no free app reaches them. For steady calling to one country, a Rebtel subscription is usually cheapest; for occasional calls, prepaid credit on Google Voice, Viber Out, or Talk360, comparing that provider's published rate to your destination first, since rates vary more by country than by app.
Do international calling apps work on WiFi only? Yes, every app here works on WiFi with no cellular service, which is exactly how travelers avoid roaming charges. A hotel WiFi connection is enough for any of them, and the WiFi calling guide covers that scenario, including options with no SIM at all.
Why did my international call fail even though I have credit? Check the dialing format first: missing country code, a kept leading zero, or a missing plus sign accounts for most failures that look like app problems. Look up the destination in the country dialing guides, and confirm the local time before redialing, since an unanswered 4 a.m. call is not a technical failure.
Is Skype still good for international calls? Skype no longer exists; Microsoft retired it in May 2025 along with its calling credit. It was the standard answer for two decades, so plenty of outdated advice still points to it. Its replacements split by use: WhatsApp for the free calls, and Google Voice, Rebtel, Viber Out, or a SIP provider for dialing real numbers.
The pattern to remember: apps for people, credit for numbers. Free app-to-app calling covers everyone with a smartphone, and one paid option matched to your destination and volume covers everything else.
