Had a motorola V60t (TDMA) and the service was horrible so I "upgraded" to GSM and got the Motorola T721. Service may actually be worse now. I maintain a PC network that stretches from Kenner to the Westbank so I use, or try to use, my phone all over NO. The service is absolutely horrible overall. In fairness though, I just got a Nokia 6820 (GSM) and I have actually been able to have 60 and 90 minute phone conversations for the first time since I left Sprint (their coverage was spectacular).

Step outside the door and the reception is great. Can't use the phones in any of the apartments though. Several friends with different models (GAIT and GSM) don't get reception in there apartments either. Cingular has a wide coverage area, but Sprint definatly had stronger signal.

Only problem I have had is customer service over the phone. I have had a very big problem with reps giving the incorrect information and not adding the correct features & promotions to the line.

TDMA works great all over southeast Louisiana and south Mississippi and has reliable to excellent service in every city/airport around the country as well as on all the highways and interstates even off in the country it works pretty well. the point is, if you must travel for work, and not always in major cities, then stick with TDMA , GSM is not reliable yet and you will miss important calls due to gaps in coverage

constantly dropping calls. wildly fluctuating signal strength. unable to make a call in any large buildings like walmart, office depot, etc... i first got a replacement T616 thinking it was the phone... it was not. the service is terrible and an honest sales rep will admit it.

reception on the TDMA network is great all over the westbank and the eastbank of new orleans. only occasional lapses in coverage like algiers near the intersection of woodland and gen. meyers, top of the bridge and a small section of magazine street. not like the gsm coverage which is a joke.
