Hello everyone, I am a newbie here to the forum! I have had some issues with text messaging the last month or so. I have an iPhone 4 through AT&T. Sometimes when I send a text it takes a long time to send then fails and I have to send it again and it goes through. At times I have to reboot my phone for the message to send. I am also receiving text messages from family / friends in multiples. It doesn't happen every time I send a text however it does happen daily. I spoke to AT&T and they stated it could be a damaged SIM card but I have friends that are having the same issue with their iPhones so I am not sure that is the problem. Has anyone else had this issue or know of a fix? I have done a backup and restore which didn't help. Thank you!
