Why are Texts blocked?


Oct 11, 2014
Text messaging not working on iPhone 5s. I can type one in but it does not go to addressee.
Also when someone texts me, they get a "blocked" message of some sort.

I recently had my account hacked- numerous calls to Cuba and had to go through vzw to re initiate my account (they had suspended due to the suspicious calls).
Maybe text problem is linked somehow?
I turned phone off and on, but is there another way to restart phone and maybe this will all go away and it will work properly?
