If you go with the main networks in the UK you get ripped off but if you buy your phone and then use 3rd parties like Lebara, Giffgaff or iD mobile then you get to use the network backbone of your choice without paying the high fees.
Lebara runs on Vodafone network, iD runs on the Three network, GiffGaff runs on the O2 network, Lyca runs on the EE network.
