Ok I've just verified with a friend of mine in Indonesia. You DO have to unregister and reregister every time you change your SIM. BB Pins and IMEI is registered at each carrier's BIS. So, in order for data services to run on the current SIM card, your PIN and IMEI needs to be registered on the current provider's BIS.
Unlocking the phone will let voice usage on any carrier, but won't let you use the data services.
Kinda sucks that people have to do this..I think they want you to roam on your BB's so that you pay them more.
Anyway, thanks for your help.

My husband and I are experienceing a similar problem I think. I have a BlackBerry serviced by AT&T. He has a BlackBerry serviced by T-Mobile. He is now in Kenya. He called T-Mobile before he left US to unlock the phone. When he got to Kenya, he purchased a SIM card from Safaricom and inserted it into his BlackBerry. He has been sending me many SMS's which I've received. However, every time I either reply back to one of his SMS's or send a new SMS to the mobile number, I get an Error message back that says " Error Invalid Number. Please re-send using a valid 10-digit mobile number or valid short code." His number appears as **************. I have also tried calling the number but it rings and rings. Can you help? Thanks.
