11. For Carrier selection mode, select one of the following:
Automatic: The cellular carrier is selected automatically by the device.
n
Manual: The cellular carrier must be manually configured. If the configured network is
n
not available, no cellular connection will be established.
Manual/Automatic: The carrier is manually configured. If the configured network is not
n
available, automatic carrier selection is used.
If Manual or Manual/Automatic is selected:
a. For Network PLMN ID, type the PLMN ID for the cellular network.
b. For Network technology, select the technology that should be used. The default is All
technologies, which means that the best available technology will be used.
Note If Manual is configured for Carrier selection mode and a specific network
technology is selected for the Network technology, your modem must support the
selected technology or no cellular connection will be established. If you are using a cellular
connection to perform this procedure, you may lose your connection and the device will
no longer be accessible.
12. SIM failover is enabled by default, which means that the modem will automatically fail over
from the active SIM to the next available SIM when the active SIM fails to connect. If enabled:
a. For Connection attempts before SIM failover, type the number of times that the device
should attempt to connect to the active SIM before failing over to the next available SIM.
b. For SIM failover alternative, configure how SIM failover will function if automatic SIM
switching is unavailable:
n

n
13. For APN list and APN list only, the IX30 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. See
instructions for setting an APN.
14. (Optional) To configure the IP address of a custom gateway or a custom netmask:
a. Click Custom gateway to expand.
b. Click Enable.
c. For Gateway/Netmask, enter the IP address and netmask of the custom gateway. To
override only the gateway netmask, but not the gateway IP address, use all zeros for the IP
address. For example, 0.0.0.0./32 will use the network-provided gateway, but with a /32
netmask.
15. Optional IPv4 configuration items:
a. Click IPv4 to expand.
b. IPv4 support is Enabled by default. Click to disable.
