Bad coverage in the UK? I live in the USA. For the past year, I've tried enabling 4g on my phone every time I go to a new city. I've never seen it work once.

Edit: In response to the dead reply "Even in the Bay Area?", since I can't seem to reply directly. Yes, in all zero of the times I've been to the bay area, 4g has worked a total of zero times.
