Interfaces
Using cellular modems in a Wireless WAN (WWAN)
The Connect IT Mini 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 interface 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 Connect IT Mini device cannot connect to the network
using SIM1, it automatically fails over to SIM2. Connect IT Mini devices automatically use the correct
cellular module firmware for each carrier when switching SIMs.
Configure cellular modem APNs
The Connect IT Mini device uses a preconfigured list of Access Point Names (APNs) when attempting
to connect to a cellular carrier for the first time. After the device has successfully connected, it will
remember the correct APN. As a result, it is generally not necessary to configure APNs. However, you
can configure the system to use a specified APN.
To configure the APN:
