Cellular antenna(s): If you have purchased the EXPLORER 540 Cellular Modem option,
the cellular modem is installed on top of the compartment on the back of the
EXPLORER 540, connected internally with a USB cable and a DC cable. The antenna(s)
for the cellular modem, however, are purchased separately and installed externally,
connected with cable(s) to the modem. The EXPLORER 540 Cellular Modem with 3rd
party embedded modem and cellular antenna(s) provide connection to cellular
networks. The type of cellular network used is depending on the purchased embedded
module, which is to be installed in the EXPLORER 540 Cellular Modem.
If you are using an external 3rd party cellular modem/router connected to the LAN
interface, see the documentation for the modem/router.

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.
Note
SIM lock: The supplier may have locked the SIM card to a specific provider. For further
information, contact your supplier.
