I've been a very happy O2 customer for more than 2 years, barely noticing any issues with the connection. My up/down links were so much better than the dodgy wired "broadband" that I discontinued the wired connection and just stick with the O2 4G for everything, including working from home.
I had no issue throughout all last year up until a couple of months ago when I started noticing unusual slowdowns and breakups. First, it was my daily standup video calls with colleagues: they couldn't hear me properly, I was breaking up and my screen-share didn't work; then later abnormal slowdown with the download speed as well.
It's very random and most of the time an airplane mode on/off will solve the issue but not always.
The coverage indicator hasn't changed, I still have full bars as before.
I wonder if this has anything to do with the Virgin Media merger? I used to be a Virgin customer and consider their service one of the worst in the land. I always had full coverage yet many times simply no connection. And noticed this in Cambridge and London as well. I'm really worried that their "quality" is now transferred to O2, where I didn't have any problems before.
Please see the attached screenshot of speeds form today, Sunday evening when it should be better than normal (since not a business hour)

Out of interest, what is your data allowance? My speeds have slowed down since I hit 90% of my allowance. I've changed my plan because I needed to up my data anyway, but if it is O2 slowing us down once we approach our data limit, and doing so without warning of a slowdown, then that's not a good look from O2
