T-Mobile is a mobile network that is part of the Everything Everywhere partnership along with Orange. As a result, T-Mobile customers can also use Orange signal and, as a result, it has one of the best 3G networks in the UK. 2G coverage is also very strong indeed and call quality is great. You can check the T-Mobile coverage map to find out about the signal strength in your local area.
Under the ownership of EE, T-Mobile was the first to launch a 4G service in the UK back in October 2012. Ofcom gave them a monopoly to provide 4G connectivity before any other network. They aim to have 98% of the UK population to be covered by the end of 2014 and use the following frequencies: 800 MHz, 1800 MHz and 2600 MHz.

T-Mobile has been running in some form or another since 1993 when it was called One2One. It was later bought out by the German national phone company Deutsche Telekom who introduced their T-Mobile brand in 2002. Since then, it has changed hands again and has now merged with French-owned Orange to form the company Everything Everywhere or EE. Together, they control a huge portion of the UK mobile phone market.
Because T-Mobile is a joint network with Orange customers can use either company’s cell tower to get reception. This means that it is able to offer some of the best signal strength in the UK. The 3G coverage is also very good for exactly the same reasons.
