Or is this just something you have to do through AT&T? Cause an ex (from like a year ago) gf's little sister is spamming my phone with texts and calls cause she is a little b*tch like that. I've tried just ignoring it, but it's starting to become very frustrating with my phone lighting up every 30 seconds with random smileys and texts annoying me. ANY ADVICE OR HELP WOULD BE APPRECIATED. Thanks.
