I have been on EE 4G in central London (Westminster) for several years now while at work. A speed test back when it was new would get me 85/85 Mb, these days, with a much more capable device, I am lucky if I get 15/30 Mb (download is being taxed more). It's not horrific, but it's a far cry from what I was advertised when I started. I guess I'll just upgrade to their 5G plan and start the cycle again sigh
