[surya018]

I face faced calling problem in indoor condition. When I turn on my mobile data, it comes after 2 to 3 minutes. I have changed my Sim from airtel to jio but same problem is happening. My secondary phone runs with jio, it has better network quality..no problem occurs.

Try without cover, sometimes the cover blocks the radio waves for signal reception.

Reset network setting of both Sim one by one and than reset all settings of your's device in general management settings also Flight ✈️ mode on n off one time, restart your's device without any Sim in slots, also interchange Sim in slots. Thanks.
