My friend got a new cell phone and gave me her old one. How do I use it with prepaid phone cards?

When my own Cingular contract was complete, I bought prepaid phone cards for my Nokia phone. Now that my friend's Cingular contract is complete, how can I use her old LG G4015 phone with prepaid phone cards, considering that she transfered her phone number to her new phone? Will this involve SIM cards?

Call Cingular and they will walk you through the process. If its a pay as you go type arrangement they will issue you a set of codes. Or at least thats the way it works with Tracfone.
Reply:call the company sometimes swapping sim cards will mess up the phone unless they disconnect the service
Reply:yes swap simcards
Reply:did the phone that she gave you use calling cards?





if it used a normal monthly plan i don't know if you can just start using cards for it..





Unless both cards have SIM cards, then take the card out of the one that she gave you, then give it to her, but i don't know if the card that she gives you will allow you to just start using calling cards. but try it anyways
