WWAN and 4G/LTE

SonicWall TZ, NSa and NSsp 13700 appliances support a number of external 4G/LTE devices. You can connect a 4G/LTE device to a USB port on the firewall to provide Wireless WAN (WWAN) connectivity to the internet over cellular networks.

The 4G/LTE 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 connection where wire-based connections are not available and 4G/LTE cellular is.

To use the 4G/LTE interface, you must have a 4G/LTE PC card or USB device and a contract with a wireless service provider. A 4G/LTE 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 changes to provide configuration pages in the DEVICE | WWAN menu group. Without a connected 4G/LTE device, the WWAN page displays the current status.
