SOUTH U.S. -- T-Mobile Roaming In South Georgia

I have used T-Mobile's prepaid service in southwest Georgia. The maps are accurate in the area that I traveled. I rode along US 19 between Albany and Thomasville and I was able to access the AT&T towers along that stretch of road. My phone went blank for a few minutes and I went into the network options and switched networks. Upon arriving in Thomasville and Albany, the phone reverted back to T-Mobile's network and I was not able to force roaming in those cities. So I'd be inclined to say that the maps are accurate. If you go to an area where T-Mobile and AT&T both have service, you will not be able to choose networks. Also the maps are spotty in some parts of the state because AT&T hasn't covered the whole state yet. In Bainbridge, for instance, there is no GSM whatsoever. Generally, you will only be able to access the AT&T 1900 mhz towers, this is why the T-Mobile coverage map is spotty. So its possible to see an AT&T phone have service and the T-Mobile one not. I hope this helps!
