SIM Lock
The BlackBerry Storm by default is SIM locked, and can be subsequently unlocked on both the 9500 & 9530 Storm editions to use on any GSM network if the code is obtained from the respective provider. The 9530 is not compatible with AT&T Mobility's 3G UMTS/HSDPA network because its UMTS transceiver only works at 2.1 GHz which is a frequency not used in the United States for UMTS, but the BlackBerry Storm will still work over the slower EDGE network in the United States and respective EDGE network from Rogers Communications in Canada.
