I was able to use chat messages instead of text messages and It was working fine. I could see if someone read my message and whatnot but occasionally it would switch to text messaging when I didn't want it to.
Now, it's all text messaging and won't switch back. I dont know if it's because I use 3 but it was working fine before and all of a sudden it stopped. I've tried practically everything.i don't know what else to do.
