About us

Three launched in 2003 as the UK’s first 3G only network, laying its foundations as the network that was born to be different.

Today Three is a connectivity company that connects people to people, people to things and things to things and has more than 10 million customers.

An average Three customer uses 3.5 times more mobile data than the industry average and its network today covers 99% of the UK population. It has the highest Net Promoter Score (NPS) of any of the mobile network operators at +12, alongside +24 for its Employee NPS.

Three also has the UK’s leading 5G spectrum holdings with more than the rest of the industry combined. Three is the only operator able to meet the International Telecoms Union (ITU) 2020 standard for full 5G services.

From July 1, 2020, Three will be the official shirt sponsor of Chelsea FC.

Three was voted the Best Network for Data at the Mobile Choice Consumer Awards, as well as Best Network for Roaming by uSwitch, and the Best High Street Retailer at the Mobile Industry Awards.
