Hi there @Cocittaa -
Some mobile operators across the world block Viber on their 3G network. Usually this happens when users have a "simple" data plan (or a prepaid contract), meaning they didn't pay extra for using VoIP on their 3G network.
In order to verify this, we recommend to:
1. Test Viber on a few different WiFi networks, and see that it works fine.
2. Contact your cell company and confirm this with them.
Furthermore, it could be that the network you are connected to is blocking Viber's traffic.
1. First, please try uninstalling and reinstalling Viber when connecting to a few different WiFi networks (in order to pinpoint the source of the problem). What are the results?
2. Also, please make sure the following ports are enabled ("forwarded") on your routers or firewalls:
TCP: 5242 + 4244
UDP: 5243 + 9785
(if you are not sure how to enable ports, you may contact your router manufacturer)
