I Have a t-mobile sim which I have bb mesenger activated. Im using this sim with my blackberry 9500 will I be able to use the sim on another bb such as the bb 8520, can use the bb messenger?
and will I have to use the PIN for the curve? and can u use my old pin?
First part of your question first - Yes you can use the SIM in another BlackBerry
PROVIDED that that BlackBerry is either from the same carrier (T-Mobile in this
case) or if it is unlocked.
As to the PIN, they are unique to each phone and not transferable. If you use
the Device Switch Wizard in Desktop Manager to copy your contacts from one
phone to the other you will be just fine. Pop the SIM into either and your
BBM contacts will be updated without your intervention.
