Error Invalid +1 (1) (216) 116-11
Suddenly I am unable to text one person who is in my address book,phone number is entered correctly (10 digit) and he can text me. However each time I try to text back or start a new message, I get the above error message back with the above number and message (number) Error Invalid Number. Please re-send using a valid 10 digit mobil number or valid short code.
I have deleted the message and contact, re-entered the contact and get the same message. I even deleted contact and message, and the turn off my phone, then re-entered same error. Any suggestions?
