• BGAN antenna.
• Cellular modem: If you have purchased the EXPLORER 540 LTE Modem option, you may
have the cellular modem installed either on top of the compartment on the back of the
EXPLORER 540, or as a standalone unit connected to the EXPLORER 540 with a USB cable.
The EXPLORER 540 LTE Modem provides connection to cellular networks (2G, 3G and 4G).
SIM card
The EXPLORER 540 requires a SIM card to go online with BGAN. Without a SIM card you can
still configure the terminal, but you cannot make calls nor access the internet.
Your SIM card determines whether your EXPLORER 540 is operating as an M2M terminal or as
a BGAN class 2 terminal.
SIM lock: The supplier may have locked the SIM card to a specific provider. For further
information, contact your supplier.
