Galaxy tab s6 lite is not detecting sim card and Freezes and restarts.

[ShweatDev]

My galaxy tab s6 lite is showing a blocked sign on the network and not showing the sim card . I erased all data and tried all most everything . It restarts automatically and freezes very often. I contacted the service center they installed a new software but it didn't work.

While playing PUBG it make a beep sound and lags so much.
