No calls or texts outside of Verizon network

[safeone2202]

I have been unable to make a call, send or receive texts to/from anyone that are not on the Verizon network or has a iphone. I received nothing from chat with customer tech support other than an outage was in area which was 3 days ago now. I've reset my network, restarted phone at the direction of tech on second and third call but nothing!  At this point, I'm beginning to think a hacking has occurred.
