Hello .
I live in Europe and i try to use a Orange SIM CARD from a Romania provider.
When i put this SIM Card in my BBERRY i get the message "INVALID SIM CARD". This mean the device is Locked on Cingular proivder ? Or the SIM Card from my cell GSM Provider not have tehnical specification ?.
The phone is sent to Romania from U.S. and have the Cingular logo on it.
Wait your opinion.
Thank's alot.

Your right.
