gov.uk serves all of the UK - including the person who lives in the middle of the mobile dead spot, and the person who can't even get consistently working ADSL. 4G/5G doesn't cover the UK by a very long way, and there's plenty of the UK who cannot afford anything but the cheapest smartphone.
It's much less common in the UK than the US to buy a smartphone on credit - cheap phones with cheap pre-paid plans are normal - so low-end models with very slow chips are more common. The sort of thing where even scrolling through your contact menu will induce lag.
