SIM ONLY · 235 PLANS ON 7 BRANDS
Keep your phone, pay less
Once your phone is paid off, a SIM-only plan usually costs less than staying on a phone contract. I've put the plans Carphone Warehouse, Ecotalk, Lebara, Mobiles.co.uk, O2 Mobiles and Smarty list in their feeds side by side, lowest monthly price first. Pick a network that works where you live and the data you need.

How I rank these
Plans start with the lowest monthly price, then the lowest upfront. You can sort by the total over the contract (upfront and every month, with the rises each retailer has announced) or by the most data instead. A plan the retailer calls unlimited still comes with the network's fair use and roaming terms, which its own page sets out.
These plans come from Carphone Warehouse, Ecotalk, Lebara, Mobiles.co.uk, O2 Mobiles and Smarty, on the EE, O2, Three and Vodafone networks. I can only include retailers whose deals reach me through affiliate network feeds, so every retailer here is one I can earn commission from. I don't cover every UK retailer or network, so there may be plans I can't show you.
Within those feeds I list every plan whether or not it would earn us anything, and nobody pays to be listed or to rank higher. Links marked Ad are affiliate links: we may earn commission if you buy, at no cost to you, and it never changes the order. No retailer, network or provider owns any part of Vouchernaut.
