Orange and T-Mobile have legally merged into Everything Everywhere, though you wouldn't know it as we're still in the paper-shuffling stage.
So everyone who worked for Orange and everyone who worked for T-Mobile now works for Everything Everywhere, but (for the moment at least) both brands will continue to exist and the two networks don't even have a roaming agreement yet.
The creation of Everything Everywhere (EE) has involved creating a few appointments at the very top of the tree – a couple of new VPs and a Chief of Staff reporting to the existing CEO Tom Alexander. EE also has its own board of directors, but people on the ground won't see any changes yet.
At least not materially – there is a new logo on the building, and everyone is getting an EE email address, not to mention ordering slightly wider business cards and bracing themselves for the inevitable staff cuts (sorry... rationalisations) where T-Mobile and Orange have duplicate facilities.
Customers won't see any change for quite a while yet: the companies are hoping to have roaming in place in the next couple of months (so Orange customers can use T-Mobile's network, and vice versa), with tighter integration to follow. ®
