I see people are mostly confused about 5G availability in their areas. One way to find out whether 5G has been started in your area is to go to network settings and manually searching for networks and if it shows 5G then it has started but not yet available to public. If that's not the case then there's another way to find out. Whenever you're passing by the nearest site to your home you can check for 5G antenna. Whether that be Airtel, Jio or Vi you'll see these 5G Antennas Installed on them. It's up to the operator when they're going to start the service. I'm posting first image of Jio 5G antennas which are installed few days ago near my area (Not useful to me because it's too far away from my home.)
