Here's a really interesting site showing how the UK's 3G/4G/5G spectrum is allocated. https://pedroc.co.uk/content/uk-commercial-mobile-spectrum https://pedroc.co.uk/content/uk-commercial-mobile-spectrum It's pretty clear that Three's spectrum is woefully lacking compared to the others, except on 5G and the LTE SDL band 32 (both not widely deployed yet). Especially problematic when you consider that Three are the ones who have been selling super cheap unlimited data packages for the last couple of years!
