Yep. As mentioned the SIM works perfectly in my XDA and my wife's NEC 3G phone.
Her SIM also fails to make voice calls in the Blackberry.
My gut feel is that this is either a RIM restriction caused by the IMEI/PIN not being fully released from the last users account OR it may have some kind of remnant IT Policy if the previous user was on a BES.
If that is the case - how can I check or fix it?
