Default Re: BlackBerry 9800 says SOS

All Blackberry phones require a specific Blackberry service plan including a Blackberry data plan to work. The SOS is because the carrier does not recognize the phone or the phone is defective.
The other reason is it was not on a GSM / CDMA .network etc. and the radio inside is not compatible with ATT network.
