Everything Everywhere losses widen due to regulatory rate cuts Theses charges will continue to fall down to 19 cents per minute for calls and 20 cents per MB for internet access by 2014. In addition, users will be allowed to choose a different operator for roaming which should bring about more competition. In today's statement EE said that the expansion of the existing regulation may have a "negative effect" on the Group‟s international roaming revenues. The company launched Britain's first superfast 4G mobile broadband service in the fourth quarter of 2012, which led to it adding 201,000 contract customers in the final three months of the year. The company, a joint venture between France Telecom and Deutsche Telekom, said more than half of its customers were now on contracts, reflecting the growing popularity of smartphones, as the company posted broadly flat adjusted core earnings. Earlier this month the owners announced they were finalising plans for a £10bn stock market flotation. France Telecom and Deutsche Telekom are close to appointing advisers to pave the way for an IPO, which the two companies have described as the "preferred" outcome of a strategic review of the recently rebranded EE. It is thought a flotation could see EE's French and German owners sell 25pc of the company with a listing on the London Stock Exchange later this year. EE was the result of a merger in 2010 between Orange and T-Mobile, owned respectively by the French and German companies.
