With Three UK I used gathered evidence over the course of 4 months to wiggle myself out of a £46/month 28-month 5G contract (had to pay £200 remaining on my iPhone 16 Pro) when I demonstrated that my phone was basically useless whenever in the postcode are where I live, even if I always had 1 bar 5G signal.

Not even phone calls would go through, let alone calls on Whatsapp et al, or loading websites using something heavier than just text.

Have raised a _formal_ complaint (they must report it to Ofcom), and after that it was just a matter of ensuring I lost enough phone calls to demonstrate how many ended up in my answering machine.

The fact that Wifi calling is also super buggy and almost never work, played also a big role.

My problem is, all other mobile providers in my area are even worse, showing LTE or 4G. So I just need to wait for them to strengthen signal, or move!

I'm a former Three user in central London. When I started it was good, then they advertised cheap unlimited data contracts which overloaded their system and they became close to unusable. You'd order an Uber, go down to meet it and be stuck because there was zero data. It wasn't a signal strength thing - it was a system overload thing.

I'm now on O2 which works kind of normally and also have a silent link esim which is a good backup. They cost like £8, never expire and let you use any UK network you choose if one isn't working. Or almost any network globally for that matter.

WiFi calling is the one of the most improperly implemented feature by carriers. Some just straight up deny WiFi calling if you're in airplane mode but connected to a WiFi.
