I have been with verizon for a long time and have always had great coverage and service.
I really want to purchase the Curve and I know Verizon wont have it for a long time. AT&T has it now and I wanted to get some advice from others on their converage in NY State, New England, new Jersey/PA and the rest of the country as I travel for buisness.
I am told TMOB will have the Curve later this year, so maybe they are the better alternative to Verizon????
The phone/email device I use is important to me, but the most important thing is the network and the ability to make and receive calls from the most locations possible.
Thanks in advance..............

I frequently travel between Long Island, NYC, Boston, and Philadelphia.
Semi-frequently to Charlotte and Atlanta.

Both my Cingular/AT&T BlackBerry and my Verizon Wireless BlackBerry work fine while travelling in these areas.
I have no experience with T-Mobile.

I have T- Mobile. They have a feature on their website that shows service areas. You can drill right down to specific addresses on their map. I was up in a remote area of Wisconsin and had great reception. I used to have Verizon and in the same area I would get a no service message.

The coverage maps are pretty useless IMO. They tell you what you should get but quite often there's a pretty good discrepancy between the map and the real world.

I've had Verizon, At&t and T-Mobile. T-Mobile seems to have the best coverage around town. Verizon has the best in remote areas. At&t was spotty all over. I currently have T-Mobile and I'm very happy with it. I'll wait for them to get the pearl.

I have TMobile. Its good for big cities and urban areas, but in the boonies, not so much. Even in big cities you may lose your connection too. Thats why its the cheapest.

I use a Cingular BB and a Verizon cell phone. Every carrier has holes and weak spots. Traveling in the areas you mention, I have not had any noticeable problems with Cingular or Verizon.

That being said, you really shoudl not let a phone drive which carrier you use. If you have no issues with Verizon's coverage, you really should consider sticking with them. But if you must switch, then I would say ATT/Cingualr is the best alternative. TMO just doesn't have the coverage across the US.

Generalizations about any carrier's coverage are pointless.

You need to check coverage with a given carrier in areas that matter to you. Each carrier has its own strengths and weaknesses when it comes to coverage. Granted, it's not a practical approach if you travel a lot and need nationwide coverge. In those cases, you're pretty much stuck with the coverage maps.
