Am I the only one who's getting a decent service then?
Reading the comments here I'm starting to wonder. I don't live in London, or in a major town, though I'm not really out in the sticks either, and I travel around a fair bit. I'm on PAYG so if the conspiracy theories are true I should be getting a shit service. However my experience over the last two years is that I've found exactly one "no signal" area (at Watford Gap services, and not a black hole any more). The only time my service deteriorates is when I'm at an event with 20-30000 other people in a relatively small area, ie large motorsport event, where I'd expect congestion to be a problem.
Maybe I'm just lucky.
