I don't use my mobile phone much (probably about 60 minutes and 60 txts pm). If the site compared pay as you go tariffs as well as monthly ones it would be 10x more useful for people like me.

identify worst packages - highlighting the key features which make them unattractive and costly

I called home from abroad a lot one month which is very unusual for me. The assessment took this into account - it would be great if I could choose to exclude periods from the assessment.

As mobile broadband deals are also sold on contract/pre-pay basis (sim cards+modems), I think they should also be included including a rating of their quality of service(We all know they advertise and say a lot but reality proves otherwise - and this is especially useful to avoid getting stuck in lengthy contracts with pathetic quality of service like from three).

For people who live outside cities, signal strength can be a deciding factor in choosing a contract. Could BillMonitor search according to this somehow?

Currently you can only choose a single phone, but in fact there are several models that I like, and the only thing that separates them is what they are going to cost me. I'd like to be able to select several phones, and have it give me the best tarrifs that supply any one of them.

Add a system so that rather than specifying individual phones, you can specify "any phone running the S60 operating system" or "any phone running the Google Android system". Those are the most important. After that "Any phone with a N megapixel camera" and "any phone without a camera", "any phone with web browsing etc."

Cookie users sot hat they are recognised and their data is accessible to them for monitoring.

I connect my mobile to my laptop via bluetooth and then I can get any network services, i.e. email and www. My provider seem to "allow" this to happen and it is a major saving as I do not need to pay for a dongle or additional extras but a colleague of mine cannot do this. I think having this capability is a big plus point if data and mobility are important to you and after all data is data so why should it mater what the originating device is or whether you are after email or the internet?

This site is ace, I think the developers should do the same but for utility bills like gas, water, elec.

Some people use voicemail a lot. This might affect recommendations.

I review my 02 bill via Carphonewarehouse.

Can your engine be adapted to compare gas, electricity and water charges?

Include data package selection on option menu as Tmobile analysis not available. Then I would be able to assess if the Vodafone or Orange deal is worthwhile, and click through directly.

My bill beat your site by ~£10 as I make use of an unlimited o2 to o2 call bolt-on your current model does not take into account that despite having say a 500 minute contract, it could be possible to make calls either to landlines or intra-carrier in excess of 2000minutes by opting for a bolt on at contract sign up. O2 for instance offer between 1 and 2 free bolts on many of their contracts.
