Persistent poor 4G,5G coverage across the UK iPhone 15 Pro HGV driver

[S21]

Hi,

I’ve been experiencing consistently poor 4G and 5G coverage for the past 1.5 years across various areas of the UK. I’m using an iPhone 15 Pro and have been a Three UK customer for about 10 years. I’ve been on a new contract for the last 6 months, but the signal issues started well before that.

As a professional driver, I travel daily across England, Scotland, Wales, and Northern Ireland. Unfortunately, I often have either very weak signal or no signal at all. Even voice calls frequently drop or fail to connect. VoLTE and WiFi Calling are enabled, but they don’t seem to make a noticeable difference.

Previously (about 1.5–2 years ago), everything worked fine. But now, the signal strength and service reliability have dropped significantly. I’ve tried switching between 5G Auto and 4G, restarted the phone, and kept everything updated — no improvement.

Is anyone else experiencing similar issues? Could there be ongoing network maintenance or known issues with coverage?

Any help or insight would be greatly appreciated.

Thanks,
Pawel

Yes shocking we live on a small island uk and struggle for signal. When in other countrys like Turkey france germany I get full signal everywhere everytime and they are not baby islands like england.

Hey, S21. 

The issue you've having is something I might think was a network issue normally, but as you're having the issue everywhere, with at best weak signal, it would usually indicate that the device is having issues.

If you have the option, it might be worth trying your SIM card in another phone to test and see if the other phone improves things.

Recently I travelled from central Scotland, to Thurso in the north of Scotland, and then shortly after, down to Wales. I was using my phone for music and general browsing, and had personal hotspot active for my daughter to watch her shows. Sure, there's a few points where the network drops out for a few minutes, mainly up North on those long country roads between the mountains, but for 99% of the journey, it ran fine. If I started having issues all over, I'd be checking my phone as well.

The signal is rubbish in West Dorset. Maybe 3 should get its 4G act together before worrying about anything else. Vodafone works so I suppose that might help following the merger, but I suppose that will be chaos for a while.
