Broadband provider Tiscali is planning to launch an MVNO service in the U.K. and is in talks with all of the country’s mobile phone operators – Orange, 02, T-Mobile and Vodafone – about renting space on their networks to carry the service. “The assessement is not if, it is who and when,” chief executive Mary Turner told the Daily Telegraph.  “The business case has already been approved by the board.”

The Telegraph report suggests the service – expected to be ‘SIM only’ – will be launched in the last quarter of 2008 and will be spun out from mobile business ToucanMobile, which Tiscali acquired last summer when it bought the Internet arm of Pipex. Tiscali says the new MVNO will be rebranded, offering a range of bundled solutions with existing Tiscali UK TV, voice and broadband services available in quad-play packages. ToucanMobile’s agreement with T-Mobile is non-exclusive and Tiscali is expected to sign one or more other networks to carry its new service. Virgin Media is the only UK operator to currently offer quad-play services.
