Three Mobile UK

Three is both a telecommunications and internet provider based in the UK – it is a subsidiary of Hutchinson Whampoa and provides both 3G and 4G services. The network was launched on 3rd March 2003 which is equivalent to 03-03-03, hence the name of the brand. The company operates both online and through its retail stores (3-stores) – the first store being in Kensington, London. In 2014, Three thought of a solution for customers that complained they were unable to get a signal in certain areas, by launching the Three inTouch app which meant customers could make calls and send text messages to other Three users over wifi. Three began to roll out their 4G services in 2013 across London, Birmingham, Reading and Manchester. You can contact the Three head offices.
