Everything Everywhere, is a joint venture between T-Mobile and France Telecom. It is the market leader in Britain in mobile phone services since it was formed in 2010. Now Telefonica's O2 UK and Britain's Vodafone will form a 50-50 joint venture to combine their wireless grid so that they can reduce costs, invest in innovation and setup a new broadband LTE (Long Term Evolution technology) network. This will help both companies compete more effectively in the British market. It is not a merger as both companies will continue to run competing services. This type of arrangement is becoming popular in Europe because of the high costs of building one's own LTE network, and makes sense, say analysts, because quality is perceived by customers in terms of speed and reliability of service than simply coverage. O2 sees the potential of reducing cell tower masts by 10% with the new venture.
