Using cellular modems in a Wireless WAN (WWAN)
The IX10 supports one cellular modem, named Modem, which is included in a preconfigured Wireless
WAN, also named Modem.
The cellular modem can have only one active SIM slot at any one time. For example, Modem can have
either SIM1 or SIM2 up at one time.
Typically, you configure SIM1 of the cellular modem as the primary cellular interface, and SIM2 as the
backup cellular interface. In this way, if the IX10 device cannot connect to the network using SIM1, it
automatically fails over to SIM2. IX10 devices automatically use the correct cellular module firmware
for each carrier when switching SIMs.
