So, my phone can't send sms to anyone for nearly a month now..I called my at&t provider twice and talked to them on the phone for an hour each. Biggest waste of time, they didn't helped much at all. Every time i tried to send any text messages, the text won't send and say "unidentified subscriber." I shake it off since BB10 is just around the corner. But lately, I've been annoyed that i can't text my friends & families. I got a couple of friends & families to get Whatsapp on their phone, but not everyone i wanted. Can anyone help me out with this month long problem ? I don't know what happened, the night before my sms was working perfectly fine till i woke up and won't send any messages anymore.

I've already tried battery pull & security wipe, but yet, i still can't send sms

Any solution ?
