I have an unlocked Storm 9530 and for some reason no matter how I change the settings I can't get the phone out of SOS - Insert sim card. I've got an active at&t sim card loaded into it.
I'm running 4.0.0.75... I downgraded from OS5.0 thinking that was the problem but I still can't get it to work.
Here are the settings I'm currently using:
(1) Manage Connections>Mobile Network:ON
(2) Data Services:On
(3) Network Technology>GSM/UMTS>3G&2G
Did you follow all the instructions in the Sticky post about an unlocked storm on AT&T? That and deleting the TCI/IP settings should make it work... you have to put ATT service books on the phone to make it work.
Have you used it before on ATT? That truly sounds like the phone is locked. I would double check because the same thing happened to me and come to know it was not actually unlocked.
