This one's a little more nuanced. The government owned (and sold off) the old copper phone lines. And yes, that sale hurt the people for two decades.
The government did not have 5G data towers. Hell, they didn't have 3G data towers. There were some 2G towers, but most of the mobile network at the time of the Telecom sale was analogue.
They have had government assistance/incentives while deploying mobile towers in rural areas, but they have pretty-much always privately owned their mobile telephony infrastructure.
