Blackberry's are unique. They require a special data plan for ALL functions to work properly. Included in this "Blackberry data plan" are things called "service books" which are(for lack of better term) software modules pushed out to the device from the carrier. On top of that, if the carrier of choice doesn't support the model Blackberry you are wanting to use, then they will not have or provide the proper service books for that model. Therefore some of the blackberry functions may or may not work.
Also, phone radios are designed for particular carriers. Different bands and frequencies. So a device designed for one carrier may or may not work with another.
That is why it often suggested to opt for a supported phone from the carrier of choice .
