I've faced some issues for few weeks due to Upgrading of Machines at back-end as they are going to release 4G/5G Services soon. Regarding my experience, I've Opt for BSNL Fiber after using JIO Fiber because in my area JIO Fiber doesn't work properly. Too much downtimes, high latency and fiber cut weekly/monthly although there machine is usually at fault (some sort of Box). BSNL provided me better experience in terms of Before-Sale & After-Sale satisfaction.
So, I think BSNL have improved alot. It's not like old time and looks way more trustworthy than it used to be. Better to get it Opted as it's a lot cheaper than fancy so-called selling Airfibers/Fibers at dumb rates
