These guys have very little technical knowledge. Last month a couple of them came to my home to enable voice calls and they didn't even know how to use an app on the phone. They could not understand what Jio call app showed. They didn't understand that one has to connect by selecting Jiofiber option and kept trying to click on Jio SIM which I don't have. It was even grayed out but they just wouldn't understand. They even laughed at my white router claiming now it was just 2500. When I tried to explain the speed difference and bands, I could tell they had no idea. One of them said, as long as you get 20 Mbps, that's all you need.
