How to Make Free iPhone to iPhone International Calls With Viber

Ads by Google

With so many apps on the App Store that offer users the ability to call using VoIP (Voice over IP) it has become increasingly difficult to tell which one is truly the best. Of all these apps however, Viber has proven to be one of the best, offering users constant updates and improvements that have made it one of the favorite ones among all similar apps available.

Let’s see some of the aspects of Viber that make it easy and convenient to use while also helping it stand out from other similar apps and services.

Viber for iPhone

One of the most important features of Viber is that once installed the app integrates seamlessly with your phone number, making it your User ID. This in turn, provides Viber with one of its main advantages over other similar applications: Instead of relying on buddy lists or lists of friends that you have to add and accept individually, Viber can instantly detect who among your friends have the app installed and will show them you with a sign next to their names.

Viber Contacts

By using Viber, you can make local and international calls to any user of the app without cost over either Wi-Fi or cellular connection (data costs apply). For calling non-Viber users, the app also includes a dialer so you don’t need to exit Viber to call someone that doesn’t have the app installed.

And since it is a VoIP app, Viber comes with push notifications built right in. That way you don’t need to have Viber open in order to be able to receive calls.

In addition to all the features mentioned above, Viber also doubles as an SMS app, allowing users to send unlimited text messages to each other for free (data costs apply of course).

Viber Chat

Overall, Viber is an excellent calling app that comes with some very smart features and that integrates seamlessly with one’s contacts. Best of all, it is free, so there is no reason not to try it.

    Hi! I LOVE Viber but I’m having troubles adding a contact from another country. He already has the app installed and activated, I have tried inserting 001 before the number, but nothing seems to work, please help me!

    We love Viber! It has been a lifesaver helping to keep us connected to our family and friends since moving to Europe 2 weeks ago! However, we do have one small question that maybe you could help solve:
    My husband and I both added Viber on our iphones when we were in the States. We have just moved to Portugal and he now has an additional iphone with a Portuguese phone number. He has added Viber to the new phone as well, but he is not receiving any of my messages or calls from my end ont he Portuguese one… only the iphone with American phone #.

      Hi,
      We’re thrilled to hear that you’ve been enjoying our app so much :)

      Please make sure that on your phone (the phone you originally brought from the States, if we understood correctly) his new Portuguese number is saved in its international format. That is: +351…….

      Now restart Viber on both devices. Does it work now?

    Received message that call could not get through because other party has older version. Text to inform them they said they could hear me (with old version) but I could not hear them with new version. Seems backwards

      Hi,

      Which devices do both of you have? Which versions of operating systems?
      Did you test it when switching between a few different WiFi networks?
