I have 100 Mbps fiber with unlimited data and landline pone service for about $103 a month (which includes all the taxes and fees).
Biggest problem with the landline phone is that people try to send text messages to it. Of course they don't go through. But the sender does not get an error message and thinks their text was sent! You would think in 2020 that they could figure out how to notify the sender that the text did not go through.
Usually the cell provider will send a message back saying it’s a land line
