Have you tried using 4G as your only connection? Even carriers that provide “unlimited” transfer typically throttle your connection after a certain amount of usage.
I use 4G as my primary Internet connection in Oslo, Norway. The apartment block where I live has a 100 years old copper line and DSL gives like 10 MBit/s with 100ms ping.
For about 90 USD/month one can get 60 MBit/s connection l both ways with ping bellow 20s. The connection is only throttled after 2 TB of data. But then you need a router and an antenna.
Or one can pay like 15 USD/month extra to upgrade the mobile subscription with 10 MBit/s connection and the throttling limit of 1TB. The ping is about 30.
