Three UK (legally Hutchison 3G UK Limited) is a British telecommunications and internet service provider currently based in Reading, England. It is a subsidiary of CK Hutchison Holdings, operating under the global Three brand. Three is the fourth-largest mobile network operator in the United Kingdom, with 13.3 million subscribers as of July 2020.

The company launched on 3 March 2003 as the United Kingdom's first commercial 100% 3G network. It provides 3G, 4G and 5G (in certain areas) services through its own network infrastructure.

Three began a limited rollout of 4G LTE services in December 2013 in London, Birmingham, Manchester, and Reading expanding to over a further 450 locations by the end of 2014. In August 2012 Three was given permission to use part of the 1,800 MHz spectrum used by EE's 4G network.

On 20 February 2013 Ofcom announced that Three had been awarded 2 x 5 MHz (10 MHz) of 800 MHz to use for 4G. Three planned to launch 4G in the second quarter of 2013, however it delayed the rollout until Q4, saying that it wanted to analyse the performance of other networks' 4G coverage first. The network provides LTE and DC-HSDPA service as a standard feature to all its subscribers using "Ultrafast" to describe both technologies, making it the cheapest price for 4G and the only unlimited 4G in the UK.

On 23 April 2015, Three mobile announced that VoLTE would be rolled out along with 800 MHz spectrum from September.
