Reliance jio is constant with the Speed most of the time so I think there is something wrong with the connection , if it is not rock solid and stable speed, there are 100 downsides to jio but the stability and reliability is one of its selling points. I got the connection sometime last year in May, yet to have a downtime, it should be noted that my state odisha is very prone to cyclones and then also I am getting this much of stability and reliability
