3g to 4g lte: New sim card?
I have an old 3g phone and it is time to upgrade. I have a 3g sim (if that even means anything) for my phone. I want a 4g lte phone.
When I upgrade (or if I buy an unlocked 4g lte phone at full retail price) to a new 4g lte phone, Do i get a new sim card? Is a new sim card needed?
