Please excuse my ignorance on this subject as I really don't know the difference between a CDMA network or GSM network. As far as I'm concerned it doesn't really matter who has a got a better so called network. The bottom line is, once I press the send key using my cell phone it connects. I am on Verizon and I can make calls and receive calls just like AT&T users. What else do you really need your cell phone to do? Is CDMA horse and buggy technology? is it really that antiquated? what's the big deal about a GSM network? Does it cook, clean and wash your clothes too? Can someone qualified in the subject please explain to me why GSM is considered superior. Hey, its not like Verizon uses walky talky technology, but apparently most of you techie types think so. Please explain.
"CDMA2000" is the primary CDMA standard that Verizon/Sprint and most other CDMA providers use. It is actually considered far superior to actual GSM technology and CDMA 3G "EV-DO" is just as advanced as 3G UMTS (UMTS is the upgrade that GSM providers have moved to). In fact, CDMA EV-DO uses less power than UMTS and can scale to similar download speeds.
In practice though, All the other variables involved in running a nationwide cellular network are far more important than which standard is used. Verizon has more towers than AT&T and overall far better coverage. All providers show coverage area on their website. Verizon in particular has a far larger 3G coverage than AT&T.
