The FSM Telecommunications Corporation (FSMTC) is a government-owned monopoly provider. It has services on more than thirty islands separated by nearly 2,700 kilometres of ocean. Main population centres on Pohnpei, Chuuk, Yap, and Kosrae have fixed line, mobile, cable TV, and broadband networks. In 2017 FSMTC supported around 20,000 mobile subscribers per their latest audit. Internet penetration in 2018 was around 53%.

The island of Pohnpei has been connected to Guam since 2010 via the HANTRU1 submarine fibre cable. Coinciding with the arrival of the SEA-US cable in Guam, the Yap Cable was built in 2018 with a grant from the International Development Association. The cable is a branch of SEA-US, and telcos are purchasing capacity directly to the United States on the cable. In 2019 the Chuuk-Pohnpei cable was built with assistance from the World Bank, connecting Chuuk with the Internet via Pohnpei's existing gateway.

The balance of the nation's 27 inhabited islands are connected by satellite and fixed wireless.
