It comes and goes and sometimes i can send but not receive texts. Other times i can't send or receive.
I've had this issue since day one and it's so frustrating. It seems to be a common problem with the M8. One thing I just tried yesterday is this: Go into Android Settings > Power, scroll down and turn off "Sleep Mode: Turn off data connection during long periods of inactivity."
So far (knock on wood) I haven't had any issues sending SMS messages since then. However, it's only been a day. I'm not sure if it will adversely affect my battery life, but if it works, I don't care!
I hope this helps!
