 what does a new sim card do? |
 |
SIM cards are the small cards which contain a chip that you need to insert into a GSM phone before it will work. Without a SIM card, a GSM phone won't be able to tap into any mobile network. The card holds all the critical information. By comparison, CDMA carriers keep a list of all phones that can use their network.
