It is a fairly well-known fact that, unlike other networks, EE restricts the ability to choose one's preferred network type. E.g., on an average Android device, navigating to Settings -> Network -> Mobile network -> Preferred network type, presents a multiple-choice list of preferred network types (usually something along the lines of 5G/4G/3G/2G, 4G/3G/2G, etc. in decreasing order). On EE, however, 5G/4G/3G/2G is the only option available.
Living in an urban area with, officially, no 5G coverage (though adjacent parts of the city, on either side do have it), the reality is there is decent outdoors coverage, which is a nice bonus. However, indoors, there is just a smidge of, completely unusable, 5G coverage, on top of the rather meagre 4G network. So while mobile data is just about usable, at a stretch, while on 4G, they are interrupted by frequent attempts of the phone to connect to 5G, during which time virtually no data is transferred. After it falls back to 4G, the connection resumes.
I'm fairly certain I'm not the only one in this position, and I would very strongly encourage EE to add this option (or more likely remove its block on it), and allow us to choose to connect to 4G (or even older) networks only - or at the very least provide an explanation on why that is not feasible, even though it seems to work fine for other networks.
(I am aware it is possible to disable 5G through a hidden system menu, but that can't be considered a universally acceptable alternative - especially for a switch one might like to flip a few times a day, on some days.)
