My contract gives me 4GB data, unlimited minutes, unlimited texts every month. I am a fairly active phone user, using it daily to get from place to place or look up occasional facts, and browse facebook; otherwise, I tend to be conservative with my data and keep data off whenever possible (total use roughly 1 hour/day). I generally don't use data for looking at videos/youtube etc. I always have plenty of data left behind (3 weeks into this month and have only used 0.5GB data). Unlimited texts really is a benefit for me as people don't always see messenger straight away and this is a reliable method of communication for me. There's free roaming within the EU which is also a great benefit as we holiday to european destinations fairly frequently and this allows us to look at maps, events and continue normal browsing (facebook etc) without a worry. In terms of coverage, I often don't get coverage in a few indoor areas or in areas where others on e.g. virgin mobile seem to get coverage (my indoor time is largely hospital and hospital accommodation, but in other indoors areas it's generally ok), so coverage only gets 3 stars. Outdoors, however, coverage is usually at least 2 bars which is fine for my needs. Connection during calls are again sometimes difficult (fuzzy voices) and I have to walk around or open a window to try and improve the connection; these are only for occasional calls and I suppose is related to the coverage issues (not very good in hospital areas). There's a wide range of contracts explained clearly on their website and I was able to select the option that best suited my needs at a reasonable price.
