4.1.1. SIM Card
If the used SIM card is locked by a PIN code, the PIN code has to be configured in the MRL-7
menu. A wrong PIN code in the MRL-7 menu will lock the SIM card as soon as the device was
started three times! If the SIM card is not locked by a PIN code, this menu item must be set to
“-1”.
It is possible to change or deactivate the PIN number, but not within the MRL-7. This has to be
done with another device (e.g. a mobile phone). The call forwarding option has to be
deactivated in every case by the phone provider to disable the mailbox.
A valid SIM card has to be placed in the marked slot of the integrated modem. It is important
to assure the correct plug direction. The SIM card also has to be placed straight into the modem
and has to be locked in the device after the insertion:
Insert sim card in the marked slot
Further instructions are available in
the MRL-7 manual.
