broadcast signals from both countries. Private ownership of satellite dishes is banned, but most households have access to the StarHub TV and the Singtel IPTV TV(mio TV) network. All radio stations are operated either by MediaCorp, the SAFRA National Service Association (SAFRA) or SPH UnionWorks. As of 1998, there were almost 55 million phone lines in Singapore, close to 47 million of which also served other telecommunication devices like computers and facsimile machines. Underwater telephone cables have been laid that lead to Malaysia, the Philippines and Indonesia. In 2002, Virgin Mobile in a joint venture with Singtel, set up the fourth telecommunications company in Singapore. It was the first mobile virtual network operator (MVNO) in Singapore. The operations were closed down on 11 October 2002 after failing to attract a significant number of customers. Failure of the joint venture was attributed to a saturated mobile market and Virgin Mobile's positioning as a "premium" brand. As for internet facilities, as of 2009, there are four major internet service providers (ISPs) in Singapore. By February 2009, there were more than 4.8 million broadband users in Singapore. However, due to the small market and possible market collusion, there have been rising concerns that various ISPs' telecommunication infrastructures being highly under-utilised. In July 2015, Liberty Wireless signed an agreement with M1 Limited that allowed it to tap on M1's mobile network, thus becoming the first MVNO, operating as Circles Asia, in Singapore to offer a full service mobile network experience. On 14 December 2016, TPG, an Australian ISP, won the bid to be Singapore's fourth telecommunications company at S$105 million. By 2019, due to the introduction of TPG and 9 MVNO entrants to the market, thus turning the market to be more competitive, the price of mobile plans had fallen. As of January 2018, there are four cellular phone operators in Singapore serving more than 6.4 million cellular phones.
