So yesterday I was just about to reply to a text I received from a friend when I tried sending it would not go through the little exclamation mark came up and I even tried calling the number it immediately said something about phone being disconnected even though I know it is not after having a face to face discussion with that person. I know my number is not blocked because there was no time for them to block it and she said it isn't blocked as we see each other everyday. I did send a message from my iPad 2 using iMessage that worked and went through. For my phone I tried soft reset network reset along with the *228 option 1. I erased the number and added it manually even added the +1 in front of the number, tried a group SMS still no change it is very frustrating!!! Please respond back @verizon so I can get this taken care of.
