Crap phone signal

Hi all, As is well documented on this sub, the phone signal here absolutely dog poo. Does anyone use a provider that has decent coverage? I'm with Giffgaff, I've been with them for years and they've always had good deals and are usually reliable. Our wifi is being spotty today for some reason so having to rely on mobile data is just basically unusable. Surely in the big 2025 we can finally build some more infrastructure?
