When I try to send a big text (approx 100 characters or more) it wont get through to the person on the other end of the line. when I send it out I end up calling the person asking if he/she got it & they would say no. I have a feeling it was advance task killer that caused it, because i had the same problem on my droid incredible. I did delete ATK but the problem is still occurring. Someone please help me!
