Vodafone Connect looks to be the not so snappy name for the new Vodafone fixed line broadband service, and we presume it will cover both ADSL2+ and FTTC based services. Vodafone mobile customers have started to receive SMS alerts suggesting that people register for the new broadband service.
Alas there is no information on what the broadband service will actually provide, but it is likely to be another bundle operation with broadband and telephone wrapped together as Vodafone is asking about peoples existing broadband and landline services. We suspect that the launch will happen shortly after the new migration process that does not need a MAC (though the majority don't need one now).
Given the extent of competition that exists in the retail broadband area any Vodafone offers will have to very special if they are threaten the likes of Plusnet in terms of customer numbers (who are believed to have around 800,000 customers), let alone catch up to Sky and TalkTalk and Virgin Media.
