Verizon FOTA (Firmware Over the Air)
At times, your device may require a critical update to radio firmware for devices connecting to the network. To
stay compliant to Verizon’s LTE requirements, you must implement FOTA. Failure to perform a critical update could
result in losing access to the Verizon network.
MultiTech has developed a script for customers to use in order to initiate a FOTA update from the (the customer’s)
local host processor (pull FOTA). The script is available at:
