10 of the best international calling & texting apps
1. Google Voice
Google Voice lets you connect your phone number to the internet, making it possible to call someone using your phone number while you're using a computer or tablet.
International calls aren't free but the rates are very competitive – calls to Canada from the US, for example, are completely free.
Google Voice also offers plenty of features including personalized voicemail, voicemail transcription, call forwarding, and spam call blocking.
There are iOS and Android versions available, as well as an in-browser option for PCs. All told, if you're looking for an international call app, Google Voice is a powerful and painless solution.

2. WhatsApp
If you're looking for a free long distance calling app, WhatsApp is your best option.
Owned by Facebook, WhatsApp is a massively popular messaging and Voice-over-IP (VoIP) app that can be used for voice, video, or SMS communication with anyone else who has the app. And, given that Whatsapp hasmore than 1.5 billion monthly users, that’s a lot of people.
The minutes you spend calling through Whatsapp won't cost you a cent if you stick to the default settings, but you'll need a strong WiFi connection.

3. FaceTime
FaceTime is exclusive to Apple devices but is a super-popular way to make and receive free audio and video calls.
Plus, it's completely free and is easy to use for group calls, making it easy to stay in touch with friends and family overseas.

4. Rebtel
Rebtel has apps for both Android and iOS devices and offers free, unlimited calls to US numbers.
Rebtel claims that it analyzes phone line traffic to give you the lowest possible price. Plus, it will also automatically find the best phone line to connect your call through – this is a boon if you don't have a large data allowance, or are stuck somewhere with no internet at all!
Rebtel also offers unlimited calling to 51 countries around the world for $8 per month, which could be handy if you have a very dispersed set of friends and family (or you lead a particularly jetset life, yourself).

5. Skype
No list of cheap international phone call options is complete without mentioning Skype.
Skype was offering device agnostic VoIP calls before the likes of Whatsapp and FaceTime made it cool. You can get the Skype app on iOS and Android phones to make free calls over your internet connection, although it is also possible to call phone lines at really low rates. The only real problem is the unpredictability of Skype phone call audio quality.

6. NobelApp
With NobelApp you can place calls through WiFi, data or access numbers, and the call rates on offer are among the lowest available on the market.
You can also send international text messages and take advantage of other NobelCom services, such as international phone cards and remote TopUps to friends or family on over 300 mobile networks. The app is available for both iOS and Android.

7. Vonage
Vonage is quite similar to Skype, but lacks video chat.
It will grant you access to some pretty cheap international call rates, while calls to other Vonage users (app or phone line) are free. One standout feature is that the app supports HD audio, meaning you'll enjoy great call quality. There are also some interesting home plans that can be used in combination with mobile devices.

8. imo
imo offers free video calls and chat across both Android and iOS devices.
Its claim to fame rests in the low internet connection speeds it requires: You can place calls with just a 2G connection. It's a good pick for someone who wants to place an international call over the internet, but isn't sure they'll have the best connection. Your backpacking friends will thank you.

9. Voxofon
Voxofon is 100% free and is available on Android and iOS devices.
The app offers high-quality video calls to any destination, with cross-device functionality for phones, tablets and laptops. The catch? You'll only be able to ring up people on your Facebook friends list. Thanks to the two billion monthly users Facebook enjoys, however, that's not as limiting as you might think.

10. Viber
Last on our list, Viber will give you access to some cheap phone call rates for international conversations, as you use WiFi to connect with other Viber users.
The app will scan your phone contacts and identify other Viber users, then allow you to call them completely free of charge. Viber is available for Android, Blackberry, Windows Phone and iOS.

These free or inexpensive apps will do the trick when you need to make an international call, but they aren’t the full story. If you need to make calls more regularly, or need a higher quality solution, don’t just reach for Google Voice – there are plenty of alternatives!
