There are now two submarine cable systems landing in Cambodia, the Malaysia-Cambodia-Thailand (MCT) and the Asia-Africa Europe 1 (AAE-1) cable systems.

The Malaysia Cambodia Thailand (MCT) cable system is the first submarine cable landing in Cambodia at the Mittapheap Cable Landing Station, put into operation in March 2017 by Telcotech. Telcotech also invested in the AAG cable system, withouth a landing in Cambodia. 

The Asia-Africa Europe 1 (AAE-1) lands at the Sihanoukville Cable Landing Station owned by Cambodia Fiber Optic Cable Network (CFOCN), in operation since November 2017.

In addition to MCT and AAE-1 submarine cables, there are various cross-border terrestrial cables with each of Cambodia’s three neighboring countries—Thailand, Laos, and Vietnam. 

The Telecommunication Regulator of Cambodia (TRC) was established in 2012, as an independent and accountable regulator striving towards a global, competitive, stable and more self-regulating telecommunications industry in order to generate economic growth and address the social needs for the development of Cambodia. 

Generally, the TRC is responsible for policymaking. The TRC is vested with regulatory and supervisory authority including the responsibility of issuing and administering licenses and the administration of Cambodia’s radio frequency spectrum. Previously the duties of reviewing laws and regulations and managing the telecommunications market were undertaken by the Ministry of Posts and Telecommunications (MPTC). So far, the MPTC simultaneously played the roles of policymaker, regulator and operator of Cambodia’s fixed-line telephone network.

The MPTC established Telecom Cambodia in January 2006 as a state-owned operator in Cambodia. 

Telecom Cambodia, Viettel (Cambodia) and CFOCN are the only three fiber optical cable network operators in Cambodia. 

According to the TRC, there are two international gateways, three fiber optical cable network operators, six mobile operators and 68 ISPs in Cambodia as of August 2020.
