I was working with a carrier called "TIGO" in Guatemala, now I will work with another carrier calld "CLARO" because they offer a better service.
But my iPhone is not accepting the SIM, how can I decode the iPhone?
Is an Iphone 4
contact the original carrier to find out if they can unlock the phone. Only the carrier the phone is locked to can unlock it. Not Apple. Not a "shop" somewhere.
