Communications in Somalia

Communications in Somalia encompasses the communications services and capacity of Somalia. Telecommunications, internet, radio, print, television and postal services in the nation are largely concentrated in the private sector. Several of the telecom firms have begun expanding their activities abroad. The Federal government operates two official radio and television networks, which exist alongside a number of private and foreign stations. Print media in the country is also progressively giving way to news radio stations and online portals, as internet connectivity and access increases. Additionally, the national postal service is slated to be officially relaunched in 2013 after a long absence. In 2012, a National Communications Act was also approved by Cabinet members, which lays the foundation for the establishment of a National Communications regulator in the broadcasting and telecommunications sectors.
