Orange and T-Mobile's new merged company has been named Everything Everywhere.
The new firm, which will be officially integrated on July 1st, will have a customer base of around 30 million people and 16,500 employees.
As well as offering the biggest operator retail presence on the UK high street, Everything Everywhere has revealed plans to create a single super-network that will offer improved levels of coverage to consumers.
In addition, roaming across both the Orange and T-Mobile networks will be launched later this year at no additional cost to customers.
Tom Alexander, Chief Executive of Everything Everywhere, said the UK was "on the verge of a communications revolution".
"It's our vision to give our customers instant access to everything everywhere, opening up a world of endless possibilities," he added.
Information about the new company has come after Orange confirmed details on its new range of data price plans for Apple's iPad tablet device.
