I spend about £1 on my Orange phone every month, my bill with O2 is £40 per month, T-Mobile £15 and Vodafone £25. Not forgetting the PAYG but I only top them up as and when, just got a Blyk one which I will be trying to use shortly. I am about to embark on a contract with 3 when I can find one for what I need but it has to be the £20 mark.
