Look at Saskatchewan, Canada. We're the only province with a public telecom, SaskTel.
Most people in the cities and even larger towns have fiber, and our cell plans are significantly cheaper than anywhere else in Canada despite being a rural province with a large coverage area to population ratio.
We also have decent electricity rates considering we have no hydro, and the cheapest natural gas in Canada. Thanks to SaskPower and SaskEnergy.
Public utilities are the only way to do it, I'm always shocked to see people defend privatization in any way.
