Anyone else's thunderbolt not sending messages suddenly? Sometimes they go through, and other times I have to retry, it doesn't matter if I am on wifi or on 4G or 3G. any clue why this is suddenly happening?
my bolt was doing that for a day or two but cleared up, you might want to do a batt pull and remove the sim card, or you want to get a new sim card that worked miracles on my sister inlaws bolt which was a 30x random reboot phone a day!
This use to happened to me. There was a + in front of the phone numbers of my contacts. I removed this and have not had problems since. Worth looking into if you have not already.
