New Unlocked phone BIS issues

Hey everyone!

I'm a newbie here and I have a little quick question. So I've had my 8900 on Orange pay as you go for a few years and I'm looking for a younger model. I am wondering if I were to purchase an unlocked BlackBerry and put in my simcard, which as far as I know should have all my BIS details on it, would the unlocked phone work? Would the new unlocked phone have all the features i.e. BBM, Email etc. Or would the phone have to be on the Orange network in order for the services to work?

I hope all of that makes sense and I would appreciate any info :)

The answer is yes, The unlock BB will work when you drop your sim into it. Just make sure the Unlock phone has the same frequencies as you carrier.

ahhh excellent, thank you!:)

What rosebud said, but also make sure IMEI is clean.
