Maybe in the developing world but I'd imagine most of the developed world got rid of wired internet and replaced it with fibre years ago.
However, I pay about 25 eur for my 5G telco (unlimited data), and 35 eur for my fiber connection (100mbit/100mbit). My telco allows dual SIM usage, so I am thinking about just cancelling my fiber connection and installing a 5G modem. The thing that is holding me back is that a good 5G modem is somewhere between 500 and 4000 eur, so it is quite an expensive experiment to do.
I was in Korea for work and it seemed the same there, I was even in eastern Europe visiting family and it was a pretty similar story. So I figured it was pretty universal. Although I know that Australia isn't in a good space with broadband simply because of politics and companies not wanting to work together, I'd assumed they were an outlier
we have fibre to about 90% of the population
Real Question: On paper, NBN is an insane human development achievement. Why do so many non-urban Ozzies on HN complain about lousy Internet access? Honestly, I don't believe it. Send them to Germany for a year, and they will see how bad it can be. (HN is full of funny stories from Germans about how bad is their broadband.)
