I have a Droid mini and im on verizon network. I can access, faceboook, the internet, snapchat, im on the wifi, I have bluetooth on, but I cant send messages or recieve them because the "mobile network cannot be accessed". I dropped my phone, and after that it isnt working. The bars symbol has a red circle with a slash through it, and it will not go away. So basicaly I am not getting the 3g or 4g signals. What can I do?
