saying cdma is a band-aid is incorrect. cdma is the future of all wireless - just with 2 different implementations.
therefore also saying 3g is better than cdma does not make sense either.
Not exactly. Most of the world still runs on GSM with the exception of North America and a couple of East Asian countries.Quote:

The biggest issue with CDMA is for those who travel. It is quite limited on where it can be used.
One big plus for GSM is that it uses a SIM for account information so that one can easily switch between them to have a local number where ever they may be. A prepaid SIM can be purchased almost anywhere.
GSM is THE global standard, albeit 2G. The "new" 3G global standard is UMTS, which uses W-CDMA. While W-CDMA is based on the CDMA stand protocols, it's actually the successor for GSM networks, NOT CDMA networks (ie. Verizon).
Verizon's CDMA network isn't actually a 3G network. At best, it's 2.5G just like GSM with EDGE.
The 3G successor for existing CDMA networks (Verizon) is actually EV-DO.
CDMA is not the future of wireless. CDMA is a dead road. W-CDMA is. W-CDMA is what existing GSM networks are being upgraded to.
I suspect that this confusion in naming is why they created the term UMTS. UMTS is the future of wireless. UMTS is sometimes called 3GSM.
UMTS = Universal Mobile Telecommunications System = international standard for voice, data, audio and video transmission to wireless devices worldwide.
I've had cingular for about 4 years now with no complaints
I've been using nextel for 4 years now, and have enjoyed the free incoming minutes, but with verizon having free incoming and 900 minutes I may change.
umm ev-do is based on cdma. Evolution - Data Optimized. what is it an evolution of? cdma. it is not a revolution, an evolution - ie, it is based on cdma.Quote:

Evolution Data Only/Evolution Data Optimized is an "evolution" of CDMA networks that is based on the 1xRTT standard, providing faster wireless data transmission speeds of 400K bit/sec. to 700K bit/sec. with a theoretical peak of 2.4M bit/sec. Verizon Wireless and Sprint Corp. in the U.S. were rolling out the service in early 2005, connecting to laptops via a plug-in card"

---------and w-cdma is too - while wcdma is different, its foundations lie in cdma (edit: you did say that as well)
http://en.wikipedia.org/wiki/EV-DO
"W-CDMA is based on the Direct Spread CDMA technique"
"W-CDMA also uses the CDMA multiplexing technique, due to its advantages over other multiple access techniques such as TDMA, and has many similarities to the Qualcomm standards. Indeed, Qualcomm receives royalties due to the unavoidable use of its patents and research in the implementation of the CDMA multiplexing technique in W-CDMA. However W-CDMA is more than a multiplexing standard. W-CDMA is a complete set of specifications, a detailed protocol that defines how a mobile phone communicates with the tower, how signals are modulated, how datagrams are structured, etc."
and btw, GSM is based on TDMA technology more than antyhing else. the only dead end technology is GSM/TDMA.
while i understand that wcdma is the upgrade path for gsm - that does not change the fact that their future upgrade path is based on cdma technology. that is why i made that statement.
all 3g technologies are based more closely on cdma as we know it today - qualcomms techonolgy - than anything else. ev-do is an evolution of it, thus it is more closer to cdma than wcdma - but in the end....
cdma IS the future of wireless - anyway you cut it.

Once AT&T acquires BellSouth it will gain total control of Cingular, the nation's largest wireless company. Over time, AT&T plans to drop the Cingular brand name to focus exclusively on its own name, people familiar with the situation said.
As a shareholder of all the companies (I owned original Ma Bell shares), I'm very familiar with the buyout and future plans. I'll be happy to be an AT&T customer again since I hate the Cingular moniker.
It was AT&T that deployed the first 3G cellular service in the USA a few years ago, not Cingular. Perhaps now they'll get back on the deployment fast track.
since i live in the UK, it would be Vodafone (tied in with Verizon in the US)
love the customer service, for example, gave me a free upgrade to the Samsung D600 for free since my contract end date conincided with the launch of the phone.
they also decreased my monthly tariff and upped my deal which in effect gives me up to 3800 free off peak minutes or 200 free peak minutes, i can mix and match.
woot!
I hate T-Mobile. :mad:
I have had Cingular for 7 years now. Always worked great till I moved to North L.A. - and got a new Sony Ericcson K750i phone - now it is so-so service. :(
