If i buy a 3 sim card from the 3 store, will it be able to work with a motorola razr v3 phone?

I have a motorola Black RAZR V3 buzz, i currently have T-mobile sim card in it, but if i buy a pay as you go 3 sim from 3 store, will this 3 sim card be able to work on my motorola buzz, if i switch the sim cards. I didnt buy the motorola from a 3 store, but just wondered if it would work with my current buzz.
