Fed up of being ripped off, and not wanting a bill phone (another "surprise" in the post every month) I think the Tesco on the 02 network is cheapest, 20C per min to any network and 9C texts..... with double top up, that effectively means it'd cost 10C per min to any network and 4.5C texts...... that seems the best value I can see.... anyone use the Tesco mobile network? is it good?
