[NishiSrivastav]

Hi Team,

I am getting a "NO" signal problem/ "No SIM Card Inserted" msg when ever I use my mobile these days in my both sim slot, please do it on priority basis as I cannot make any calls. I checked with JIO and Airtel network customer care and they couldn't found any problem and asked to check with Samsung and mobile issue.

Regards,

Samsung Customer

1. Try with a SIM that has good reception
2. Try inserting your SIM to other devices for checking
3. Try Factory Reset
