Every BlackBerry has "Subsidy code" or "Sim lock code". To remove BlackBerry subsidy code or sim lock a special Blackberry IMEI Unlock Code is needed. By entering Blackberry Unlock Code on your BlackBerry you can use your Blackberry with any GSM and SIM card around the world. Blackberry Unlocking is simplest way to remove any or carrier restrictions from your Blackberry. Remote IMEI unlocking is the safest and fastest way to unlock a cell phone.
Get this Blackberry Storm 9530 Imei Unlock Code .i hope this will help you :)
Good Luck.

The phone is unlocked but it does not recognise sim card. I have the same problem as well, so there must be a solution than trying to sell people unlock codes when the phone is already unlocked

It's have to be unlocked, Enter http://blackberrymep.com and follow instructions there, it's the best solution for unlocking your blackberry, it's easy, fast, cheap i have tried many other methods, but i found it the best.
