I'm in Tucson, AZ...and I used Verizon, then T-Mobile, then Alltel. To date, I've had the best voice and data coverage with Verizon and Alltel and the coolest, cheapest phones with T-Mobile. The problem I had with T-Mobile was that the data and voice service availability just really sucked. The service was fine...when I could find a signal...but that was rare.
I would check the coverage maps before actually getting in bed with a cell carrier.  But there are Pro's and Con's about both..In India at least, CDMA handsets do not hold a SIM card. So you can't change your handset (or its not as easy a process). I often bet with my friends and we're shuffling between our handsets, thanks to versatile SIM cards! Besides, CDMA is used for cellular as well as FWT services. In case of FWT, I think that's the best solution for quality. But of course, GSM is an internationally accepted standard. And people tend to roam. So all odds favor it - for the compromise in quality, we would use GSM technologies in the future. I didn't agree upon that SMS taking a long time to be sent thing though! I've never seen that around! 
CDMA has more bandwidth hence has greater data clarity but it is not widely used worldwide.
whereas GSM is used in most of the countries and it has several enhanced features like, GPRS, EDGE etc. QUOTE(vitorious @ Mar 24 2007, 02:34 PM)  I work for a cellular provider in Canada and we use GSM (huge hint  ) were coming out with a new data network I think Verison just beat us to it called HSDPA (High Speed Data Packet Access or something) its pretty interesting double the speed of the CDMA providers network right now. With data and now video calling starting to become the norm it will all depend on data speed not call quality in my opinion.-Jordan You work for Rogers Communications Inc.? They are the only Canadian provider to use GSM. xboxrulz
As of now, I don't really care.. but would prefer GSM to CDMA...
and, i can bet tht UMTS is not long from overtaking the rest! QUOTE(solanky @ Jul 4 2005, 01:05 PM) Hi, Now a days there are two different technology for mobile phones in the world. (1) CDMA -Code Division Multiple Access (2) GSM - Global System for Mobiles based upon TDMA ( Time Division Multiple Access) There are some countries where GSM is the major technology and CDMA has entered recently like India. On the other side there are some countries where CDMA is the main technoloy and GSM has entered recently like USA, Canada as far as I know. What you think about these. I mean which technology you like and why??? And which will win in the race between these two in the future. I think what matters most is the uniformity of the mobile technology. Mobile phones are about communication so it is important to make sure that the message/phone call is sent to the recipient, regardless if it is GSM or CDMA.
Here in Australia, the big telco has just starting phasing out the CDMA network to make way for the third generation network it has recently deployed around Australia. This means, by January next year, there will be no more CDMA in Australia!

Does that mean your country can only use 3G phones then? 3G is still quite expensive to use and implement, not ideal for the consumer. xboxrulz
We are still using the GSM network in Australia. Telstra has phased out CDMA in rural areas (cause thats where it was mainly used) and has replaced it with 3G, so the rural, country folk have to upgrade, but the GSM users in town don't HAVE TO just yet.
Telstra has almost finished implementing 3G coverage across Australia. Because the 3G handsets can roam on the 3G and GSM networks, this means that people with 3G compatible handsets have more then, i think they said 99% coverage over Australia. I don't yet have a 3G handset, only because I don't need it. Yes, the extra speed that the EDGE network has is great, but I just dont need it yet. And as you said, its quite expensive! To purchase a 3G phone is very expensive, though Telstra has just released 3G Pre-Paid, which will be good for some people. You can even watch Pay-TV channels on your 3G mobile now! |
