Hi,

I am going abroad soon (out of europe) and i will be changing the sim card on my blackberry, I have currently registered and have the blackberry service on Vodafone and i have decided to get the BIS on t-mobile for only a month while im away.

I was wondering, if i try to register t-mobile sim with the blackberry service and insert in my phone, will the BIS work as i am already registered with vodafone?

Also will i have to make any changes on my phone?

And finally when i decide to change back to my vodafone sim will it still work or will i need to do anything?

You will need to unlock the BB to work with another carrier. You will also need to cancel your BIS service to set it up on another carrier and then cancel with that carrier once you get back. And if you use the carrier supplied email address, you cannot transfer it to the new carrier and it will likely not be available when you get back.
