Services Telephones Fixed telephones In the UK, there were 35 million (2002) main line telephones. The telephone service in the United Kingdom was originally provided by private companies and local city councils, but by 1912–13 all except the telephone service of Kingston upon Hull, Yorkshire and Guernsey had been bought out by the General Post Office. Post Office Telephones also operated telephone services in Jersey and the Isle of Man until 1969 when the islands took over responsibility for their own postal and telephone services. Post Office Telephones was reorganised in 1980–81 as British Telecommunications (British Telecom, or BT), and was the first nationalised industry to be privatised by the Conservative government. The Hull Telephone Department was itself sold by Hull City Council as Kingston Communications in the late 1990s and celebrated its centenary in 2004. Mobile telephones There are more mobile phones than people in the UK. In 2011 there were 82 million subscriptions in the UK. There were 76 million in 2008 and 55 million in January 2005. Each of the main network operators sells mobile phone services to the public. In addition, companies such as Virgin Mobile UK, Tesco Mobile and Global act as mobile virtual network operators, using the infrastructure of other companies. Numbering There is a set numbering plan for phone numbers within the United Kingdom, which is regulated by the Office of Communications (Ofcom), which replaced the Office of Telecommunications (Oftel) in 2003. Each number consists of an area code—one for each of the large towns and cities and their surroundings—and a subscriber number—the individual number. Mobile IMSI is the actual number assigned to it the mobile telephone number, and provided with individual license to the MNOs.
