First off I would like to introduce myself! I am new here and have been lurking for a while! I work off of 8700c, 8820 (ATT) and I own a Curve (Tmobile) So I figured it was time to join and post!
I am working on a Blackberry 8700c (ATT) and it is not texting to different carriers (Tmobile and Verizon). I have switched devices, wiped the phone, checked the memory, and switched the SIM. Is there anything else I could possibly do?
