Does anyone out there with internal info see any problems with these maps?
To my knowledge, those maps are accurate. Verizon/Sprint/Alltel have always gotten more and better reception than T-Mobile/AT&T wherever I've gone, especially inside buildings and tunnels and where the landscape would interfere.
If you want to dig a little deeper, Verizon usually has better reception than anyone, and AT&T usually has better reception for their technology (GSM/HSPA).
I do know for a fact that EVDO is much more widespread than HSP...
go to att website and find a 3g coverage map, you cant get a national one, you must zoom in a little more.
then go to vzw and check their 3g map. you can get national, and the differences are tremendous!
not even comparable
I'm using sprint's evdo rev a 'cause it is everywhere I go (west tx, ok, mo and ks) and it is extremely reliable. Still using att for voice, but when that contract expires.....
