    Occassionally, my phone shows that no sim card are detected (even though SIM cards are there). It happens usually in the morning when I use my phone after a few hours break. Turning on and off the airplane mode doesn't work. Whereas, restarting the phone can temporarily solve the issue.

    Anyone on the same boat? Any permanent solutions, please?

    Try to Reset WiFi, Mobile & Bluetooth -
    Settings - System - Reset Options - Reset WiFi, Mobile & Bluetooth.
    It might help.
