I put my ATT SIM card on an unlocked Blackberry 9530 and everything works fine including receiving SMS/text. However, I can't send SMS/text and got messages saying "unidentified subscriber".
When I put that ATT SIM card on my Blacberry Pearl 8100, I got no problem. I can send SMS/text.
Please help me how to fix my 9530. Thanks.
