SIM status OK even though NO SIM is present

In case the SIM card is removed and inserted back while the charger is operating, then an incorrect status of the SIM card is shown and consequently the charger can’t communicate with the mobile network.

EXPLANATION:
The charger shows the right status when the SIM is removed, but when it is inserted back in then the status doesn’t change and because of this the network communication fails.

SOLUTION:
The SIM card should only be inserted or removed when the station is not operational. In case of any sort of manipulation with the SIM card is done when the charger is in operation then a reboot of the charger is needed.
