AutoPIN
SIM security enables device recovery following (occasional) power cuts without on-site
intervention and helps prevent fraud. SIM security is achieved using the AutoPIN feature.
The PIN code is programmed in the terminal’s memory where it is relayed in unusual
situations. When AutoPIN is in use, the SIM card is useless to any outsider.
System monitoring
Connection between the Nokia 30 and the application module is checked periodically by live
checks. Based on the live checks, the Nokia 30 and the application module can be reset
automatically if the connection between them breaks. This feature only exists in the M2M
system mode (see Chapter 0) when traffic is sent through the M2M system connector.
Authentication
The terminal and Gateway authenticate each other when circuit switched data or high speed
circuit switched data is used. This kind of authentication can be used in the M2M System
mode.
