The Ovivo Mobile Freedom proposition is an interesting one, and it goes a little something like this: pay a one-off £15 for an entirely decent monthly allowance, and in exchange occasionally watch a few seconds of ads in your browser.
The monthly allowance has been increased to include 150 minutes, 250 texts and 500MB of data.
Ovivo Mobile is an MVNO (mobile virtual network operator) using the Vodafone network.
