This roaming agreement practically enables a t-mobile subscriber to be reachable where ever there's gsm service. . .

The roaming agreements are to enhance coverage where T-Mobile has none. If they have service in a market that, say Cingular, serves, you can't roam on Cingular when you're T-Mobile signal is weak or not available.
Take NJ as an example, NE part of the state has excellent coverage while other areas can be hit or miss. I can't roam on Cingular when T-Mobile has no signal in NJ. Well, I can roam but I get SOS Emergency Calls Only.
According to a thread in
www.howardforums.com, T-Mobile signed a bunch of roaming agreements recently and the coverage map is much larger than the T-Mobile map on thier site, Amazon has the latest map. I think they also allow you to get M2M free when roaming now.
Actually I hope I'm wrong and you're right so you can tell me how to get that to work. It'll make things much better for me.
