So my problem is basic yet frustrating. My phone is 3 months old. For a week now it has been failing to make calls. Whenever I try to make a call. The call just cuts like I pressed the end button.

It isn't with my carrier because used different sim cards with no change. I also scoured my settings and cannot see anything that would cause this problem. Any help right now would be appreciated.

 

The problems started on with the carrier I've been using for since the beginning so I don't think that is the problem. I just tried the new one to troubleshoot.
I am able to communicate via sms so that isn't the problem either.
It sounds like I should just take it to get fixed.
