NOTE
The LT-3110 Control Unit must be powered off when inserting, changing, or
removing the SIM card. The SIM card is hidden behind the rubber dust cover on the
back side of the LT- 3110 Control Unit.
Figure 17 shows an Iridium SIM card. The format is Mini-SIM (2FF) 25 x 15 mm. The SIM card must be
removed from the full-sized card carrier by breaking the Mini-SIM out. The full-sized card carrier
contains the MSISDN number, while the SIM card itself contains the ICC-ID.
Figure 17: Iridium SIM card example
The SIM card will be delivered from the Iridium Service Provider (ISP) together with the essential
information:
• MSISDN number (the Iridium voice number)
• ICC-ID
• PIN codes
• PUK codes
The SIM card will be delivered with the SIM lock feature disabled. Thus, the Alphatron LT-3100
Iridium will be operational as soon as the SIM card is inserted. If the user decides to activate the SIM
lock function from the UI display, then the PIN code is required next time the Alphatron LT-3100
Iridium is powered up.
NOTE
Change of the SIM card PIN code can only be performed if the PIN lock is enabled. If
changing the SIM card PIN code, then the SIM card default PIN code cannot be
restored, and the new PIN code must be used to unlock the SIM card and the
Iridium services.
