I have a t-mobile phone and I just bought a cingular blackberry from ebay do you think the sims card will work

Question

in my new blackberry???

Answer 1

If you're service provider is tmobile, the cingular blackberry will not work, unless by chance you bought an unlocked phone.

An unlocked phone means its not bound by any provider, any sim card will work in it.

How to check for that, I haven't a clue, if it was unlocked, i'm sure they would have said so.

If not, you're stuck.
