Everything Everywhere will announce the details of its 4G rollout next week.
The mobile operator will announce its all-new 4G brand at the Science Museum in London, at 9am on 11 September.
The company told journalists it will have "exciting information on our new brand and the latest innovation in network technology".
Everything Everywhere, which is a partnership between T-Mobile and Orange, will launch its 4G network on existing spectrum after a landmark decision by Ofcom.
Everything Everywhere has previously said it will be October before it can launch the 4G network - but that's still at least six months earlier than would have been possible if we'd been waiting until after the spectrum sale, currently set for early 2013.
Needless to say, HuffPost will be there for all of the key details.Suggest a correction
