8 Security
The basic security feature of the W2x terminals are the same as any GSM
phone, using a PIN code that comes with the subscription SIM card. The
PIN code is simply entered via the WUI. To simplify usage, the W2x
terminals have an auto PIN feature that requires the PIN code only to be
entered the first time the unit is used or upon changing the SIM card.
Additionally the W2x terminals provide security features that prevent
unauthorized use of the SIM card and the unit, which can be customized if
required.
8.1 Operator Lock
This feature controls the W2x terminals network access, based on whether
the SIM matches one or more of the following criteria:
• Mobile Country Code (MCC) and Mobile Network Code (MNC)
• Additional Mobile Country Code (MCC+) and Additional Mobile
Network Code (MNC+)
MCCs are defined in ITU E.212 (“Land Mobile Numbering Plan”) for use in
identifying mobile stations in wireless telephone networks, particularly GSM
and UMTS networks. A MCC is often used in combination with a Mobile
Network Code (MNC) in order to uniquely identify a network operator.
Both the MCC and MNC are part of the International Mobile Subscriber
Identity (IMSI) number, which uniquely identifies a particular subscriber,
and is stored on the SIM card.
The unit can be locked to one or two specific mobile network providers.
8.2 PIN Lock
This feature locks the SIM card to a unique unit by changing the PIN code
to a new randomly value. As a result, the SIM card cannot be used in
another terminal unless the PUK code is known.
8.3 Mechanical Anti-Theft Kit
A mechanical anti-theft kit is available as an accessory. The kit consists of
a wall bracket with an anti-theft detail and a special anti-theft key for
removing a unit that is locked to the wall bracket.
