Every time I turn on my device, I get this text message from 1121611611 that reads, ..."453 Error Invalid Number. Please resend using a valid 10 digit number or shortcode..." Granted, I am using an unlocked T-Mobile phone on ATT network but have never seen this before - It only happens when I power off the phone then back on again - ideas?
Is the phone setup with att ? If not you kneed to call them and let them know so they can setup the phone settings on there end that is what a rep. told me when i changed phones my self.
