Hey, I've had this phone for about a week now, its preused but when it came it was in pretty good condition. I'm not sure if its because i'm a total no0b when it comes to phones or if i've been fiddling with it too much, but the phone now can only recieve texts. I can't send out. When its processing, it'll suddenly say "SMS send failed." I reeeally don't know what to do. A little help is very much appreciated. Thanks!!!
