You could then get a prepaid SIM overseas for voice calls but you'll need a suitable phone in addition to the Blackberry.
AFAIK no carrier offers Blackberry data on a prepaid SIM so it's not really an option.
I just got $30+ in charges just for keeping my phone in france! I am on Cingular Blue (ATT). Most of the charges are not even related to an incoming call going to VM. Apparently, everytime i turned my phone off and back on (or if the phone lost the network for a min), the phone tries to call the VM system (in the background) to check if you have a new VM and i got charged $1.29
I always thought thet the VM system works like push email where the sysstem transmits data to the phone to tell it there is new email. i was wrong at least based on Cing cust serv
