Orange UK and T-Mobile have joined forces to establish Britain’s biggest communication company, Everything Everywhere. The company has a customer base of 40 million people, or half of the UK adult population.

The joint venture will bring few changes to customers. Orange and T-Mobile will continue to work as separate brands in the market. Each will have its own shops, marketing adventure and service centers. Everything Everywhere will be the behind the scene company that will run Orange and T-Mobile.

"Together, we are Britain's biggest communications company, with over 30 million customers. We are on the verge of a communications revolution. Up until a few years ago, mobile was just about voice and text - not now. Multimedia phones have already started to change the way our customers access the world - for entertainment, education, information - wherever they are, whenever they want,” said Tom Alexander, Chief Executive of Everything Everywhere.

The company has new business plans. Everything Everywhere expects it can generate new revenues from mobile advertising and mobile commerce and will introduce more services for business customers. In addition, both Orange and T-Mobile expect that the merger to result in total savings of £3.5 billion by 2014.
