About Three Mobile

Three UK is a mobile phone network provider and internet service provider based in the United Kingdom. They are a subsidiary of Hutchinson Whampoa. They started in 2003 and provide their own network infrastructure with a wide coverage of 3G and 4G services.

Three stores opened up around the same time as the network was launched and Three began a persistent phone and online marketing strategy that would cause it to increase their customer base rapidly in their first few years. 95 of their physical stores were purchased from “The Link” and “o2”.

SeeMeTV was launched on Three. This was a chance for people to make video’s and charge small micro-payments to other Three subscribers, to watch the videos. The video’s creator would then get 10% of that fee once they had accumulated £10.

Three mobile has been breaking barrier since they started out in 2003. They were the pioneers of mobile TV and mobile video – tools of entertainment that have become only more popular with the increase in possible 3G and 4G mobile transfer internet speeds.

In 2014, Three announced that it would launch it’s “inTouch” app (reference). This allowed Three subscribers to use an available WiFi network to route calls and text messages if signal was interrupted or non-existant. This was essential for London underground passengers as they could communicate via the Virgin network.
