Alaska has 4G LTE coverage concentrated in its populated cities and towns, with vast wilderness areas having limited or no mobile service. Anchorage, Alaska's largest city, has strong 4G and expanding 5G on T-Mobile and AT&T throughout downtown, Midtown, the Dimond Center corridor, and Ted Stevens International Airport (ANC). GCI (General Communication Inc.) is Alaska's dominant regional carrier with the widest rural network across the state. Fairbanks has solid 4G in its city center, university corridor near UAF, and along the main commercial strip on Airport Way and College Road. Juneau, the capital, has 4G in the city center, Douglas Island, and near Mendenhall Glacier visitor area. The Kenai Peninsula including Homer, Kenai, and Soldotna has 4G along the Sterling Highway and main town corridors. Seward has 4G in the main town but signal drops quickly on the Resurrection Bay ferry routes and in Kenai Fjords National Park. Kodiak Island has 4G in the town of Kodiak. The Matanuska-Susitna Valley including Wasilla and Palmer has 4G along the Parks Highway. Denali National Park has no reliable 4G inside its boundaries. The town of Healy at the park entrance has limited 4G. The Dalton Highway to Prudhoe Bay has no commercial cell coverage beyond Coldfoot, approximately 250 miles north of Fairbanks. Southeast Alaska communities including Sitka, Ketchikan, and Skagway have 4G in their town centers but no service on open water. All national parks, most national forests, and remote coastal communities have no service. Satellite communication devices are the only option in these zones.
