Re: my s4 active is not receiving calls and it does not call also
Bring the phone into your carrier. If could be the SIM card, it could be something messed up in their database or it could be a problem with your phone.
If your calling or message recieving isn't working anymore on your S4, that is due to the new update for the phone.. It's a bug that doesn't allow your phone to do those things. Otherwise check settings and make sure everything is enabled
