Okay right now I have Virgin Mobile and I'm going to be switching to either Cingular, T-Mobile, or Verizon Wireless very soon. I noticed that the call quality I have with Virgin is very poor due to Sprint's network. The other day I used my friend's T-Mobile phone to make a call when I didn't have my phone, and I noticed that the call quality and clarity was excellent.
Cingular and T-Mobile use GSM technology, while Sprint and Verizon use CDMA technology. How is the call quality between Sprint/Virgin and Verizon? How is the call quality between Verizon and T-Mobile/Cingular? Which carrier do you prefer and think is best?
Also keep in mind that I live in southern California around the Los Angeles area and I travel out of state usually only once a year to areas that aren't extremely rural so the whole analog roaming crap with CDMA phones doesn't really apply to me.
Thanks.

GSM is usually stronger in the cities, but in rural areas it's pathetic mainly because the networks are newer and just haven't had time to be built up. CDMA has analog coverage, so you'll get reception in places you wont' with GSM, as well as places inside buildings where it can use analog. I'd go with Verizon, unless the other companies had a very good offer to you and you don't leave a big city much.
Hopefully this'll clear it up a bit for you

Listen here is the deal, GSM is a worldwide network with alot of perks to it. Also GSM has expanded across the US in vast ways. CDMA sucks and will always suck its a old network and who now a days wants something that is old tech?!?! answer me that and you have your answer

GSM is easier to get and you can use it anywhere in the world. You go to another country and still use ur phone if you buy a new chip.
CDMA in the U.S. is very good. I would say that its the best technology. The call quality is superior to GSM.

o.k i don't have to argue with you!!!! how long do you know about cdma and tdma? they the first technology here in the u.s. even around the world. when gsm kicks in and easy to play all cdma and tdma network is gone. i can say gsm is a fast growing network but cdma and tdma is the best. sometimes on your gsm when you making a call your phone say SYSTEM BUSY and your call cannot go thru. this is not happening to cd and td, they allways looking for a short cut just to connect to the person you are calling. japan have the best techonogy and all we know when it come to tecknology they the best. why japan use cdma instead of gsm? because as i said cd and td are the best. you know how to research! why don't you research first before disagree with me.

just always think about japan and korea. they almost cover the world with their product. (cars, t.v, dvd camcoder, comp, ect.) but look at this 2 countries they still use cdma. japan use WCDMA and korea use CDMA. why? because cdma transfer everything very fast. pictures,logo, ect. if you have a gsm and the international roaming is activate you can go to any country in the world and if you check your phone you still have signal. go to japan with your int. roaming sim your not gonna get any signal. you have to rent a phone to them and put your sim into that phone in order to make a call. this is what cdma do. they good but i think here in the u.s to operate gsm is alot cheaper than operating a cdma. but if you gonna ask me! i still want gsm. as i said they cheap to operate and the tri-band phone can be use anywhere except japan and korea.

Gsm is a more global service than cdma. If you want a phone that works outside the US, you better get a gsm phone unlocked.

I think it all depends on where you use your phone and
what you use it for. I live in a semi rural area and seldom
ever go to the City (SF). I avoid the freeway whenever
possible and I don't fly on commercial airlines anymore.
Only on private Jets. I have iDEN- Motorola's propriatary
network now and it works very well in my house and
most places that I need to use it around here.
Motorola now makes a " world phone" that works here in
the US at 800 to 870Mhz and European GSM at 900Mhz.
American GSM in 1900Mhz, and there is no sharing with
the old rural AMPS system in most of the mountainous
areas that I need to use a phone, but neither does iDEN.
But American GSM is getting better and it will probably
take at least 5 years before they can catch up to the old
TDMA networks that they want to bump out of buiness.
Who knows, maybe they will never catch up.Basically I
think GSM is for flatlanders (city folk) who are used to
waiting in line for everything, and can tolerate a lot of
noise and delays. I have had Verizon (GTE Mobilnet) CDMA
that I was not happy with the dropped calls and poor
voice quality, kinda sounded digitally-tinney. The very
best service I have had was with AT&T TDMA. The best
voice quality and NO dropped calls, and it worked in more
places than any other carrier for me.I had Nextel iDEN
6 years ago and it sounded digitally, but now I think it
has improved greatly, and I am a firm beliver in Motorola
phones and radio equipment. I don't really know but all
my friends who have other phones besides Motorola don't
have any way to hook up an external antenna and amplifier
if need be. Motorola developed the first radio phones and
I trust them to deliver the best quality and durability.

What makes a top notch phone ?
A top notch phone to me is metal, not plastic. It has to have all the new
generation features that I need. I definetely don't need bluetooth, because I am trying to minimumize RF transmissions around me. I
would never wear a tranceiver on my head, and only use a real car kit
with external antennae in my vehicles, so if your Kiocera phone doesn't
offer a real car kit it is definately not top notch. I think the cameras
offered in this country are no where near top notch- a free 1.3 megapixel
camera only adds thickness and weight to a phone. I need at least 5
megapixels. Check out a Sony T1 camera.
A top notch phone to me is the smallest , slimest, lightest , compatible
with TDMA (most Powerful) network that has a speakerphone and a REAL
car kit availible that has the best voice quality. My i830 has text
messaging but I don't have time for pecking at a little phone during my
workday, I use a computer for text. If I do any traveling to other
countrys it's for vacation and if I need to call I'll use a land line, and I
would never bring my laptop computer to the beach, the sand would ruin
the computer and the computer would ruin the vacation. I guess it all
boils down to whatever makes your boat float.Last edited by Dr. Pasquale; 07-26-2005 at 08:05 PM.

There seems to be a lot of mis-information regarding CDMA and GSM
GSM. Advantages are you have a huge phone selection and as long as the phones unlocked and supports the band it will work on any GSM provider such as cingular or t-mobile in the states. Voice quality? I have only used t-mobile and the voice sounded very robotic, it sounded great on my end but horrible to other users and they said I was always staticy sounded bad. Used a v600, samsung e105, and their pocket pc phone edition. GSM Phones are also normally smaller and coverage is great in the metro areas. Battery live is good too.
CDMA. I currently use Verizon and while the phone selection isn't big, that isn't to say the phones aren't good. Most people get the idea that "CDMA" phones are big and ugly and old. Look at sprint, yeah some bad coverage but they have some of the best phones in the US right now. Verizon although not having too many good phones has released some nice phones (LG VX8100 is a pretty sweet phone). Alltel has also released some decent phones as well. The phones are bigger because they use the Qualcomm chip hence the phone is just slightly bulkier than the GSM sets. Battery life is not as good but coverage is exellent.
CDMA is not older than GSM. You have to remember Europe never had the infrastructure for landlines like america and hence MUCH more people use cells there. CDMA is a much newer technology and was built from the ground up to work with data, it has a higher capacity. GSM was built mainly for voice. GSM is pretty much TDMA but a world standard for europe, and a large portion of asia. CDMA is moreso for south korea, japan, and north america. W-CDMA is not the same as CDMA, it's actually a better version of GSM. Nextel is NOT GSM despite using a sim card OR CDMA. They used the iDEN technology. It's actually quite funny because there are so many people that are not tech savvy many still think cell phones are analog or use satellites.
