I get 50Mbps with 4G connection for 20euros per month. No data cap. Public ipv4 address.
Router is 4 years old Huawei 4g router and I have installed outdoor antenna on the roof for stable connection. I have been with this setup at home for the last 4 years.
I could propably get faster connection with new router but this is fine.
4G has been my only connection at home since 2013. I pay 20 euros a month for unlimited 50Mbit/s 4G connection and I can watch two Netflix 1080p streams and do other things at the same time easily. ISP also provides public IPv4 address so I can run servers at home. I live in Finland.
