Deutsche Telekom and France Telecom have unveiled Everything Everywhere (E2), the new name for their combined UK mobile operators, Orange and T-mobile.
The new company, which received regulatory approval in March, has some 30 million subscribers, making it the biggest mobile network operator in the UK, pushing O2 into second spot with Vodafone third and 3UK fourth.
Everything Everywhere is expected to post pro forma 2009 sales of £7.57bn and earnings before interest, taxes, depreciation and amortisation of £1.38bn.
New CEO Tom Alexander will head 16,500 employees and more than 700 retail outlets. E2 will be officially integrated on 1 July, but will retain the two brands for marketing purposes.
Alexander said he planned to create a single "super-network" that will give bigger and better coverage for customers, with a smaller impact on the environment.
Roaming across both networks was due later this year, at no additional cost to the customer.
Alexander said the UK was on the brink of a multimedia mobile communications revolution. "Multimedia phones have already started to change the way our customers access the world, for entertainment, education, information, wherever they are, whenever they want," he said.
He said the company's new coverage and scale enabled it to "ramp up" offers to the business market.
