It is true that cingular has a large coverage area, why are you saying that you can't roam with them? I know that one of their roaming partners is Dobson Communications which covers many rural areas. I have T-Mobile and might be switching to Cingular, i live in a rural area so i've been looking at roaming partners, T-Mobile has many and i am having a hard time finding Cingulars on their website but yes you can roam with cingular, if you don't like verizon and sprint doesn't have the coverage you want either i'd say go for it, most providers have a trial period in which you can back out if you don't like them.
In Illinois where I live Verizon wireless has many "dead spots". Don't like them.
I have had Sprint and been happy with them .
But Cingular is supposed to have a large coverage area.
But with Cingular your phone can't roam.
With Sprint you have the option to go off there network if there is no Sprint coverage.
So, Does Sprint have a better coverage area?
Between the 2 who has the better network?
