Good coverage all over town and in big sky, but not in the canyon on the way to Big Sky... not that any other carrier does. Over all, it's good. But all my friends have verizon, so I have to pay for txt msgs.

I have just recently arrived on campus and have been all over town, testing my AT&T reception along the way. I get nothing. Searching... ..

No cross over service for AT&T pay as you go customers - shame on you AT&T - I should be able to spend my balance where ever I choose. It is 2008 not 1988 - get your switching agreements sorted and your act together. Why is it si can go to any country in Europe with my UK vodafone plan and call of any network (at a price I will agree) but I cannot evev switch state in the US and still use the same SIM card / service provider. In fact AT& T stink.

Sprint blows here. I'm lucky if I get "hello" out and hear the party I'm calling's response before the call is dropped. My phone has basically become useless. Just the other day I tried calling a friend. After my phone dropped the call four times I gave up and called him on the landline. Pathetic. Why am I paying $90 / month for the pleasure of owning a phone that doesn't even work?

I would like to say that I would like some way that it would make it easier to talk to such as an earpiece and if my cell phone service effects other cell phone compaines.

Cell phone service in the Gallatin Canyon and upper Gallatin Canyon clear to 10 miles outside of West Yellowstone on Hwy. 191 is none existent. Why not install a tower in some of the open areas alongside the hwy at least right before entering Yellowstone?!

Service jumps from G to not G. Service cuts off in calls as the towers don't hand off. And I'm not moving around when this happens. From past experience I know that Verizon doesn't cover the interstates. Had no connection for all I-80 in Nevada once I left the cities. Cingular / AT&T has most of freeways covered.

Fine service around the Bozeman area, but gets spotty when you're in the canyons.

It seems that there is a mixed bag for T-Mobile users in Bozeman. I get 2-3 bars when I am in town and my wife gets 0-1 on her phone. As we head out of town, we almost immediately drop 1 bar (meaning wife gets none and I get 1-2) and the further from I-90 I get the more likely I am to get no service.

Tower must have a malfunction. Most of the time I have to walk up a block to be able to get my messages (1-2bars), but I could not make a phone call with it. I have to go up to the 6th floor of the engineering building to be able to make a phone call.
