Very disappointed for the last couple of months now. Everytime I try to make a phone call it says voice cellular calls can not be made at this time. But then I turn my phone off and back on mostly it will make a phone call. Sometimes it does not. Then I turn off again, back on them usually it will go through. All my text messages are fine and do what there supposed to do. All my other apps seem to be working fine. It's just the voice calling. In the phone's app it's not highlighted but shows on
