The U.S. is but one exception and uses both GSM and CDMA (Code Division Multiple Access).

    Phones about the GSM network are able to use any carrier’s network, reducing the costs to the carriers and its particular users. Europe mandated using GSM in 1987 as well as the phones and equipment because of these phones be cheaper to fabricate.

The alternative applies for CDMA phones – you can’t decide to switch the signal from a fresh phone minus the permission of your respective carrier. The carriers for CDMA don’t have to accept your phone onto its network.
