Not sure how true this is, and perhaps someone else more knowledgeable than I can confirm this, but I've been told that with the roll-out of 5G over the last couple of years, 3G cell towers are being decommissioned leaving areas that aren't covered by 5G more susceptible to poor network coverage. So previously, if you weren't able to obtain a 4G connection, it would resolve to a lower bandwidth signal on 3G. This is because 5G uses shorter radio waves than its predecessors - 4G & 3G. This also means the range of this radio signal doesn't travel as far, so while 5G is great if you're near a 5G cell tower, generally in this country, and with three mobile, it's just #!@%
I've been with three mobile since 2014. Back then and up until 2020, it was great, never had a problem. However, I've noticed a massive negative change in the reception, and I can only conclude this is down to recent infrastructure changes. My partner is on EE with the same phone, and her coverage seems significantly better than mine, so once my contract is up, after a decade as three mobile customer, I'm definitely switching. I realise that my experience with three mobile is subjective based on my location, but generally I think the sentiment is if you're experiencing poor coverage, researching local service quality and possibly switching to a carrier with better coverage in your area is a sound approach. Three mobile just isn't working for me anymore.
