The History of Three UK

As a relatively new network provider, Three UK has worked hard to establish itself since it was founded as a subsidiary of Hutchinson Whampoa in 2003. When the network launched as the UK’s first video mobile network and a solely 3G operator, it also began opening stores in key locations. The first two 3Stores were opened on Oxford Street and High Street Kensington in London and one at the Birmingham Mail Box. Whilst you could visit a store and buy a Three handset and contract, they were also sold by independent mobile telephone chains and stores throughout the UK and online.

With the success of Three UK in the first two years, they set about expanding 3Stores across the UK, which included Bluewater Shopping Centre and The Mall at Cribbs Causeway in 2005, as well as purchasing 95 high street shops from O2 and The Link in October 2006.

Seen as innovators in the telecommunications industry, Three also set about launching SeeMeTV, which was a video channel where Three customers could upload their own videos and ask other Three users to subscribe and pay a nominal fee to watch – earning money and notoriety at the same time.

Other significant moments in Three history include them being the fourth network to launch the iPhone in 2010, along with Vodafone, Orange and O2. They also rolled out 4G service in 2013, which has expanded vastly since then, as well as the launch of the InTouch app in July 2014, which allowed users to route text messages voice and video calls through a local Wi-Fi network when there was no Three mobile network signal.
