The mobile network in the U.S. Virgin Islands has evolved significantly over the years. Historically, the islands have been served by various telecommunications providers, including Liberty Communications, Viya, Claro Puerto Rico, and T-Mobile US. These providers have contributed to the modernization of the telecommunications infrastructure, transitioning from traditional wire line services to digital switching and fiber-optic cable and microwave radio relay technologies.

Currently, the U.S. Virgin Islands have a mix of cellular services, with some areas experiencing uneven coverage. Studies have highlighted that cellular coverage is far less than what is advertised by commercial service providers, with many areas having poor or no signal, even in relatively populated regions. This uneven coverage is particularly evident in the northwest and eastern portions of the islands, where the loss of a single cell tower can significantly impact service availability.

The islands' mobile network resilience has been assessed in various studies, which have identified vulnerabilities in the existing cellular services. These studies have used physics-based models to predict coverage gaps and areas where service is vulnerable to tower outages, providing insights into the types of critical infrastructure that could be affected.
