Another data point: Australia basically only has 3 nation-wide mobile networks.
They're broadly compatible from a handset perspective - sometimes there's better coverage for one or the other in some area or newer tech but for most day-to-day use you can get a SIM from any carrier and expect to be able to use it any (non-network-locked) device.
I wonder what the percentiles is for number of networks in populous and large countries. Perhaps 3 networks is the number of maximum economically viable long term networks due to the enormously high cost of installing all the fiber and cell station infrastructure across the country.
