Blackberry storm 9530 t-mobile? help

I'm going to buy my friends blackberry storm 9530 it's carrier is t-mobile and its an unlocked phone...I was wondering if I buy it is it possible to use prepaid cards instead of going contract like he has in anyway? like buying those cards monthly? or whenever they run out? thanks.

 

Are you talking like long distance cards they sell at super markets and stuff? Or Prepaid T-mobile cards?

 

im asking like if ill be able to use prepaid cards on a blackberry storm 9530 since my friend has contract. since if i buy it i dont want contract

 

I believe that AT&T and T-Mobile both sell Prepaid SIM cards that you could place in your phone and it would work just the same.
However, for prepaid companies without SIM cards... I'm not sure exactly how that would work.

 

Unless your friend payed a cancellation fee for the contract (this is if it is associated with the payment towards the phone), you will be stuck with the contract.
