I've been using 5G as my primary internet connection since January 2020. It's much faster than wired broadband in buildings that don't have fibre installed. It's also cheaper (I pay £30/month for unlimited data), there's no contract locking you in to 12 or 24 months of service, and I can take it with me whenever I travel or if I move house.
I have a Huawei E6878-870 5G mobile WiFi (other brands are available), which provides a "proper" WiFi base station, so no need for a phone hotspot. I have a separate cheap SIM card for my phone.
