No SIM card refers to your device does not have any physical SIM or embedded SIM. But you are 100% sure that a SIM card is inserted into the device.

Your physical SIM network is not available; this situation is different from the No SIM card available. In such cases, your device identifies the SIM card but can’t connect to the cellular network. It may be due to the weak network coverage or if you are out of your coverage area.
