About WWAN

All SonicWall appliances support either LTE-only or LTE+5G external devices (LTE/5G) with the exception of the NSsp 15700, in conjunction with the fail-over feature of SonicOS. You can connect an LTE/5G device to a USB port on the firewall to provide Wireless WAN (WWAN) connectivity to the internet over cellular networks. WWAN devices can also be used for Load Balancing (LB) with existing wired WAN connections.

An LTE/5G connection can be used for:

• WAN failover to a connection that is not dependent on wire or cable.

• Temporary networks where a preconfigured connection might not be available, such as at trade-shows and kiosks.

• Mobile networks, where the SonicWall appliance is based in a vehicle.

• Primary WAN connections where wire-based connections are not available and LTE/5G cellular is.

To use the LTE/5G interface, you must have an LTE/5G PC card or USB device and a contract with a wireless service provider. An LTE/5G service provider should be selected based primarily on the availability of supported hardware. SonicOS supports the devices listed online at:

By default, the firewall tries to detect the type of device that is connected. If it can successfully identify what kind it is, the left side navigation provides the WAN device and network details in the DEVICE | WWAN menu group. Without a connected LTE/5G device, the WWAN page displays the current status.
