SIM Only Plans

A SIM only plan gives you calls, texts and data for the phone you already have, usually for much less than a contract with a handset. GleeSim compares SIM only plans on EE, O2, Three and Vodafone, from 20GB to unlimited data, with EU roaming on many of them. Plans start at £12.50 a month.
