Founded in 1960 as the Guam Telephone Authority, it was originally established as a government-owned public corporation.

The company provides a comprehensive range of telecommunications services in Guam, including wireless, landline telephone, internet, and digital television services. GTA operates the island’s most extensive fiber-optic network and maintains a significant mobile network infrastructure. The company has played a crucial role in developing Guam’s telecommunications infrastructure, including the implementation of 4G LTE technology and fiber-to-the-home (FTTH) services. In 2019, GTA expanded its capabilities by partnering with Kelly Telecom, enhancing its service offerings and technical expertise. The company serves both residential and business customers, providing enterprise solutions, data center services, and managed IT services. GTA has been instrumental in connecting Guam to major submarine cable systems, strengthening the island’s position as a telecommunications hub in the Pacific region. The company continues to invest in network modernization and digital transformation initiatives to support Guam’s growing telecommunications needs.
