As of today, whenever I try and text this one person I get "We're sorry but you cannot send this text message due to limits set by your wireless account owner." I can still text everyone else but no just this one person in particular and I'm wondering why. Any help?
Sounds like one of your parents (assuming they're the account holder), put SmartLimits on your phone to prevent you from texting that person. You'll need to discuss with the account holder.
