Do they not have 4G or LTE there yet?
Not where I live, no. But apparently there is 4G in the centre of Norwich. I've yet to discover that though.
I do live in quite a rural area of the country (compared to where most UK users on here live) and in most parts of the UK you can't even get a decent 3G signal let alone 4G!
I'm sure I can get 4G in London though, so next time I'm down there I'll post a Speedtest screenshot.
