bsnl sim getting off automatically

[mahendran]

I am facing a strange problem in my Samsung S7 (2017),dual sim mobile.

I use Reliance jio and bsnl sims.

however,my bsnl gets into off mode automatically,in the sim manager.

I can switch on it. but it gets to off mode,periodically or randomly.

can anyone guide me the reasons if any? is there any settings related issues.

What happens if you Interchange the SIM's. See if the same SIM or the sim in the same SIM slot behaves this way.
