Viber calls - Nokia 7610

Sure, go here:
Viber Free Calls and Messages
Viber Free Calls and Messages

Check in settings, notifications if Viber is allowed to send notifications. Also, check Viber settings for that too.
Besides that, 95% of android phone have this problem with Viber simply because Viber isnt really fully optimised unlike the IOS version.

good luck :)

I dont use Viber myself, I can only suggest few things:
*check online to ensure your tablet is supported by Viber ( compatible to run that Apps) I know some phone wont work with the apps.
* check your viber to see your setting has "anyone" or "contacts only" this latter one means you can not receive call from people that is not on your phone book listing.
* try to see your volume is on inside the device setting (the audio).

• Install the Bluestack HD App Player from this link (Emulator for Android) in the Windows operation system.
• After Download and install the Bluestack emulator for Andoind
• Install the Viber APP.
• You can click my apps to find your entire installed APPS, you can able to find Viber as well.
• Click home screen and open Viber.
• Select country and enter your mobile number and press OK.
• You will receive the verification SMS on your phone (no need smartphone) and keyin the verification code in the viber app (running on PC).
• You can add your friends number in the phone book.
• Click Free call to call your loved once or click Free message to message them.

Hi,
This is an official representative of Viber.

Please try removing Viber, wait 24 hours, reinstall and try again (make sure you try both the SMS and the automated call options).

In addition, you may try to register to Viber with a different number (for example - your home landline number, a friend's number, etc.), in order to determine whether the problem is specific with your number, or a general one.

If this doesn't help, contact our support team at http://support.viber.com and give them the details of the problem.
