Best International Call Company in 2026

Rebtel is our pick for most frequent international callers. It offers unlimited monthly plans for many popular destinations, plus pay-as-you-go credit for occasional calls, so you can match the plan to how often you call. Its local access numbers are a real advantage: when internet is weak, you dial a local number and Rebtel connects the call over phone lines, which keeps calls stable where pure internet calling drops out.

The catch is that unlimited plans are priced per country, so a plan for one destination does not cover calls everywhere. Check the plan for your exact country, read the fair-use terms, and compare the monthly plan with pay-as-you-go credit if you call more than one country each month.

Google Voice is the simplest low-cost route for people based in the United States. Calls to US and Canada numbers are free, and international calls are charged at low per-minute rates that you can check before dialing. It works from a browser as well as a phone app, and it keeps a separate number for calls, which some people prefer for privacy.

The limit is availability. Google Voice numbers are for US residents, so it is not a general solution for callers based elsewhere. International calls are also paid, not free, so heavy callers to one country should compare Google Voice rates with an unlimited plan from Rebtel or Boss Revolution.

Viber covers both sides of international calling in one app. Calls and messages between Viber users are free, and Viber Out lets you call landlines and mobiles that do not use the app, at rates that are often low for popular destinations. That mix suits families where some people use the app and older relatives only have a landline.

The trade is that free calls only work app to app, so you still pay for landline calls, and rates change by country. If most of your calls go to one landline number, compare Viber Out with a pay-as-you-go specialist for that destination before you commit to credit.

WhatsApp is the default free option for most international families, and for good reason. Voice and video calls between WhatsApp users cost nothing beyond data, calls are encrypted, and the app is already installed on many phones around the world. For daily chats with relatives who have smartphones, it is hard to beat.

The limit is that WhatsApp cannot dial a landline or a mobile number that does not use WhatsApp. If you need to reach a business, a hospital, or a relative without a smartphone, pair WhatsApp with a paid service such as Rebtel, Viber Out, or Boss Revolution rather than expecting one app to do everything.

Boss Revolution suits callers who want flexibility without a monthly bill. You can add credit and pay only for the minutes you use, or pick an unlimited plan for a country you call often. The app also supports free app-to-app calls and money transfer features, which some families use alongside calling.

Rates and plan availability depend on where you live, so the US, UK, and Canada offers differ. Check the rate for your home country and destination together, and note that an unlimited plan for one country does not cover calls to other countries.

Localphone is a quiet specialist that competes mainly on price. Its per-minute rates on many routes are among the lowest we found, and it offers local numbers that make calling a regular contact feel like a local call. For a caller who watches every cent and calls the same numbers each week, that focus is a strength.

The trade is a smaller feature set. Localphone does not try to be a messaging app or a money transfer service, and its brand is less well known than Rebtel or Viber. If you want one app for calls, messages, and video, look elsewhere, but if price per minute is the main test, Localphone deserves a check.

TextNow is best known for a free US and Canada phone number, and that free tier is genuinely useful for people who need a second number. International calling sits on top of that base service, so it works as a secondary option for occasional calls abroad rather than as a dedicated international specialist.

The catch is focus. TextNow does not offer the same range of unlimited international plans as Rebtel or Boss Revolution, and the free service is supported by ads. Use it as a free US number and an occasional international backup, and pick a specialist for heavy international use.

Vonage fits households that want to replace a traditional home phone line. It provides a home number that works over the internet, with plans that include international calling to selected countries. For a family that still uses a home phone and calls relatives abroad from it, Vonage keeps the familiar setup while cutting the cost of a traditional line.

Casual mobile callers will find Vonage heavier than needed. It is a monthly subscription service, not a pay-as-you-go app, and setup takes more effort than downloading an app. Choose it for a home phone replacement, not for a single trip or a few calls a month.

Amantel keeps international calling simple. You buy prepaid credit, dial, and pay per minute, with no monthly subscription to manage. That model suits occasional callers who want to call a real phone number abroad without learning a new app or committing to a plan.

The trade is a thinner app experience. Amantel does not offer the messaging, video, or money features of larger platforms, and its rates still vary by destination. Check the rate for your country before buying credit, and keep the balance small until you have tested call quality on your route.
