Network Lock
Network Lock prevents the use of an unauthorized SIM
card in the iGATE FCT. Once Network Lock is enabled, if
an unauthorized SIM card is used, the iGATE FCT will not
process either incoming or outgoing calls. Instead, it will
generate an error tone on outgoing calls and will reject
incoming calls.
Network Lock feature may be either disabled or enabled
when you receive the unit. To change the setting, call
Technical Support.
PIN Code Programming
Certain countries require that every SIM card be assigned
a PIN code. The purpose of this requirement is to protect
the SIM card against unauthorized use.
Overview
To use a PIN-code protected SIM-card, activate it and
insert it into the iGATE FCT. Every time the unit powers
up, it delivers the stored PIN code to the SIM card. If the
code matches, the unit functions normally. If the code is
wrong, the unit locks itself, ceases functioning, and the
STATUS LED blinks. See “Clearing a Lock” on page 14.
Note:
The unit locks in order to prevent the SIM card from locking.
SIM cards lock after 3 failed tries. Once the SIM card locks, it can
only be unlocked with the PUK number.
The PIN code protection can be used in several ways:
•
PIN Code protection can be disabled. Then, use any
SIM card programmed to function without a PIN code.
•
Use the default PIN code of 1234. The unit is prepro-
grammed with this code. Use a SIM card pro-
grammed to require the default code 1234.
•
Use a custom PIN code. Use a SIM card with a
known PIN code and to program the code into the unit.
Enabling Protection When the PIN Code is Known
If the SIM card’s existing PIN code is
known
, there are
two possibilities:
1. Insert the SIM card into the unit.
2. Dial ** 1343**#. The unit enters the programming
mode and emits the confirmation tone.
•
To enable the feature using the SIM card’s existing
PIN Code:
a. Dial *6110*#. The unit emits the confirmation tone.
b. Dial XXXX# — that is, the existing PIN code
followed by the # sign. The unit emits the
confirmation tone.
