Jio 5G is just "naam ka 5G" now. I tried using it for a month and it just chokes up in crowded areas which honestly is an inconvenience for me. This was the only reason I kept using Airtel 5G even though their postpaid plan prices are very high compared to Jio. Airtel 5G never disappointed me, even in crowded areas it just works fine most of the time. I am able to make UPI payments, stream content and make audio calls without any fuss 99% of the time although I have been facing a lot of call drops with Airtel recently.
I think we should not be surprised with this kind of performance from Jio, it has always been like that. They heavily market their products with "unlimited data" and "free trial" but when it comes to core performance, it just disappoints. I had poor experience with both their wired broadband and wireless cellular connection. I have always felt that although Airtel copies Jio, they do it the right way somehow.
