First, let us know if you're happy with any type of Sim

Include full contractsOften cheaper and you're locked in for 1yr+, but there's usually a credit check
Include rolling contractsUsually no credit checks and you can leave after a month
Include pay-as-you-goYou're not locked in, there are no credit checks, but it can work out more expensive if you use it often, and you have to top up
You can filter your results when you click through if you change your mind, and can tailor your results, eg, data amount, preferred network etc.

We've only just launched the Cheap Mobile Finder tool and we hope it's simple and intuitive to use.

This is early days though and we plan to continue to add more bells & whistles to it. So do please send feedback, suggestions & bug reports.
