@mgs I should add, you can have broadband via 5G, with an antenna at home. But it’s hard to know how solid that is, you should do tests with your phone and people on other networks to try and understand the quality of the network. BT offers it (EE network), Vodafone, Three, etc
Big downside is that it can get clogged in the evening when everyone watches Netflix and plays PS5, the speeds drop, and the weather can also affect it. And if you’re next to a popular London area, forget it.
