Problem here. So I woke up this morning and had two text messages on my phone which i tried replying too and I sent both of them and went to take a shower and came back and neither of them sent. So I tried again and again and no more luck at all. I keep getting (SMS error 97, Message ID 178) Service Denied.
Now mind you I have always paid my bill in the same way and the same time of the month every month since i got a phone 4 years ago so its not like they shut my phone off. I have full bars and my internet still works and what not.
