UK's largest consumer broadband provider, Talktalk, has announced that it will sign a strategic partnership with Vodafone to launch its own mobile phone service and use its huge user base of more than four million customers to join the select club of triple players.
Talktalk may be looking to emulate the success of Virgin Media which has started to do cross sell Virgin Mobile contracts to its own customers. Using an established network like Vodafone also means that Talktalk will be able to cover most of the UK from the start.
Interestingly, Talktalk will be competing with sister company Carphone Warehouse - from which it demerged back in April - which has its own mobile network, Talk Mobile, which has its own agreement with Vodafone. Carphone Warehouse is of course Europe's largest independent seller of mobile phones.
And let's not forget that Talktalk will also be offering free Canvas boxes when the video over IP service comes to market sometimes next year. Getting television (something that Tiscali, another company that it acquired, did well) will make of Talktalk the second quadplayer after Virgin Media.
