There is some information about Alaska, which is very different from the other 49 states. T-Mobile doesn't operate any GSM network natively in the entirety of Alaska and has no prepaid roam coverage at all.

The only two GSM operators in the state are AT&T, which has a decent coverage, and GCI, an Alaska-only operator who partners with T-Mobile where both GCI and T-Mobile postpaid roam to each other. Thankfully GCI sells their own brand of prepaid called "fastphone" at decent rates, and has very wide 3G coverage including rural areas plus limited LTE coverage in cities.
