Go to T-Mobile's website, locate a store, then give them a call to find out if they have SIM copiers.
Are you talking about copying over the phone numbers from one SIM to another? Or, are you talking about copying your active SIM info itself to another card, so you can have two or more phones ring on the same number without switching SIM cards? I didn't think the latter was possible (thought each SIM has unique number, just like each mobile device), which is what I believe this OP wants to know. Please correct me if I am wrong about this. JT
