This is going to sound paranoid; but 6 weeks after I signed a 12 month o2 contract - having had 1 year of relatively okay service on rolling month o2 contract - data on my phone virtually stopped. Needing navigation or websites out and about is imposssible, sites will not load or take so long the moment has past. I've tried the sim on my older phones - even tried a friends newer phone, but the same issue. I have a US provider on my virtual sim and have to take the financial hit on that if i really need to get something off the net when not near a wifi spot. I pay nearly £30 pm and have 6 months left. My calendar is littered with reminders to cancel the moment i can! None of the other networks are amazing - but o2 and 3 are the worst for coverage, with o2 by far the slowest I've encountered having used 4 of the major providers over the last few years.
