Jio internet stops working automatically after feel minutes

I am facing a weird issue on my iphone se 2020 for quite a long time. My Jio Internet stops working automatically after every few minutes, like less than 5 minutes.

I have to put the phone on airplane mode to make it work but then after a few minutes, it stops working again. It's a repetitive process of turning airplane mode on and off for Jio internet to work.
