The Three contract I'm currently on is quite average for the price ... it includes unlimited data, texts, international roaming in some countries, and 200 minutes of voice a month for around £30 (if I recall correctly). The coverage is spotty, much like other phone networks, though. I can't tell the difference of what 4G is supposed to be. I have previously complained about poor connection in specific regional areas, but very little could be done. The Wuntu app offers some good deals every now and then for Three customers exclusively.
