Domestic vs. international calls
The phone number that you’re registered with on Rakuten Viber will determine your call type:
Domestic call: The caller and the receiver share the same country code in their phone number.
Example: If your phone number begins with +1, and you’re calling another +1 phone number, even if you’re not in the US or Canada, it will still be considered a domestic call.
International call: The caller and the receiver have different country codes in their phone number.
Example: If your phone number begins with +1, and you’re calling a +44 phone number, even if you’re both in the US, it will still be considered an international call.
IMPORTANT
There are no extra charges for making an international call, however, Viber Out may not be available for some domestic calls.
Is mobile data used during a Viber Out call?
To make a Viber Out call, you must be connected to the internet (mobile data or WiFi). Your carrier will not charge standard calling fees.
The receiver of your call doesn’t need to be connected to the Internet; however, they must be in an area that can receive phone calls.
Notes
If you are traveling abroad you can continue making Viber Out calls at no extra charge from Rakuten Viber. However, you should familiarize yourself with roaming and other charges that may be set by your service provider. To avoid extra charges, keep your phone on airplane mode and only use Viber Out when you’re connected to WiFi.
Will the recipient of my call be charged a fee?
The recipient of your Viber Out call may be charged a fee by their phone provider, just like they might for any other incoming call. Rakuten Viber does not charge recipients for accepting a Viber Out call.
How long can a Viber Out call last?
Your call will automatically be disconnected after 4 hours; however, you can redial immediately to continue your call.
Can I make Viber Out calls from my desktop?
Yes! You can use either World Credit or a plan to make a Viber Out call from your desktop.
Note
Plans can only be seen and managed on your phone; however, although you won’t see it on your desktop, you can still use your plan to make a Viber Out call.
