The United States Minor Outlying Islands (USMOIs) have a limited and specialized mobile network infrastructure. The primary focus is on providing critical communication services for emergency landing points, military presence, and scientific research. The islands have a few airports and seaports that support limited scheduled commercial services and occasional military activities.

Historically, the development of mobile networks in the USMOIs has been driven by the need for communication in remote and strategic locations. For instance, Midway Atoll, Wake Island, and Johnston Atoll have been important stops for aircraft and military operations, necessitating the establishment of communication infrastructure. The islands' remote nature and limited population have constrained the development of extensive mobile network coverage, with services often being project-based and focused on specific needs such as emergency response and scientific research.
