In Norway if one has a copper phone line into house, then the speed is typically bound by 40 Mbit/s. And it is not just rural areas. The apartment I live in is close to the center of Oslo. But as it is an old building with few flats it is not profitable to lay down the fiber even if it is just extra 10 meters from the near office building. With 4G with a good phone or modem one gets 50-300 MBit/s depending on the provider and coverage.
