(relay of the BBC World Service) and the SaintFM Community Radio. Occasional amateur radio operations also occur on the island. The ITU prefix used is ZD7. Online Saint Helena Island Info is an online resource featuring the history of St. Helena from its discovery to the present day, plus photographs and information about life on St. Helena today. Saint Helena Government is the official mouthpiece of the island's governing body. It includes news, information for potential visitors and investors, as well as official press releases and pages from the major government departments. Saint Helena Tourism is a website aimed at the tourist trade with advice on accommodation, transport, food and drink, events and the like. Television Sure South Atlantic Ltd (Sure) offers television for the island via 17 analogue terrestrial UHF channels, offering a mix of British, US, and South African programming. The channels are from DSTV and include Mnet, SuperSport, and BBC channels. The feed signal from MultiChoice DStv in South Africa is received by a satellite dish at Bryant's Beacon from Intelsat 20 and Intelsat 36 in the Ku band. SAMS formerly produced a weekly TV news broadcast, Newsbyte, which was also published on YouTube. Telecommunications Sure provides the telecommunications service in the territory through a digital copper-based telephone network including ADSL broadband service. In August 2011 the first fibre-optic link was installed on the island, which connects the television reception antennas at Bryant's Beacon to the Cable & Wireless plc Technical Centre in the Briars. A satellite ground station with a satellite dish installed in 1989 at The Briars is the only international connection providing satellite links through Intelsat 707 to Ascension island and the United Kingdom. Since all international telephone and Internet communications are relying on this single satellite link, both Internet and telephone service are subject to Sun outages. Saint Helena has the international calling code +290, which Tristan da Cunha has shared since 2006. Saint Helena telephone numbers changed from four to five digits on 1 October 2013 by being prefixed with the digit "2", i.e. 2xxxx, with the range 5xxxx being reserved for mobile numbering, and 8xxx being used for Tristan da Cunha numbers (these are still shown as four digits). Mobile telephony started operating on the island by late 2015. A full set of services is available from Sure. Sure South Atlantic has an exclusive public telecommunication licence until 31 December 2022.
