TalkTalk has been an MVNO several times already
I'm assuming this is just a statement from TalkTalk copied and pasted as an article. Wasn't really anybody at The Reg able to spot the fact that TalkTalk has been an MVNO for many, many a year now? Just not a very successful one, perhaps. I have been with TalkTalk mobile for about 1.5 years, starting from somewhere early 2006. This was using T-Mobile as a carrier.
Then there was Talk Mobile (single 'Talk' - not two of them!). I know, very smart of them - trying to confuse their own customers. With different set of support phone numbers - just so that you had to spend the whole day figuring out which TalkTalk MVNO department you really belonged to. I believe this was using O2's network - but I'm not completely sure on that. Definitely using a different carrier then TalkTalk mobile.
Then they had FreshMobile (which apparently closed this spring) - and another MVNO which I can't remember. OK, you might argue that FreshMobile actually was part of Carphone Warehouse - but the other two are more obvious - just look at the names.
So please - the article should really read - "TalkTalk is to (re)launch (another) own mobile service".
And to El Reg - I am disappointed.
