Oh wait, you usually can't because most of the world uses UTMS not CDMA.
Can't use CDMA phones, but guess what.... UMTS is W-CDMA.  UTMS is W-CDMA. But CDMA by itself usually references CDMA2000.
Current wireless technologies:
W-CDMA: GSM/UTMS/HSPDA/HSPA/LTE (all same family)
CDMA2000: 1xRTT/CDMA/EVDO/UMB (all same family)
WiMax (only currently used by Clear)
1. CDMA2000 is not compatible with UTMS networks.
2. Verizon will be using LTE instead of UMB in the future to become compatible with its parent company Vodaphone which uses UTMS based systems (as does most rest of the world)
3. Sprint was using GSM in some cities but switched to CDMA and iDen (Nextel). Currently planning on using a combo of CDMA200, WiMax, and LTE in the future. |
