Talkmobile is a mobile virtual network operator (MVNO) operating in the United Kingdom. The company is owned by The Carphone Warehouse (CPW) and is run on the Vodafone network.
The company was launched in 2007, first offering just four payment plans before expanding into a wider range of tariffs and products.
CPW's original MVNO was called Fresh Mobile and used to run on the one2one/T-Mobile network. Fresh was discontinued in 2010 in favour of TalkMobile.
