SOS on 8700c
all, I just unlocked a cingular branded 8700c. I have tmobile service. when i put my sim card in it detects the tmo network and shortly there after displays SOS and never detects the network again. I put my sim card back into my 7290 and it works fine. don't know what to do. HELP?
How old is your SIM card? when the phone is not unlocked it would say sim card rejected.
Go into your options menu and make sure that the Network settings are not locked into another network. Set it to automatic if it is.
still not working
i got a new sim card. it is set to automatic. can anyone tell me what the difference is in using a cingular unlock code and a blackberry unlock code?
