Wrong target
This is from a telco that in 2018 throttled California firefighter data plans at the height of the Mendocino Complex Fire,
Alternatively, California firefighters used a commodity SIM with a data cap for a safety-critical application. Rather than the decision maker getting fired for selecting the wrong plan, it's much easier to blame Verizon.
Ok, so it's generally easy to blame the telco, but this was a great example of an avoidable IT risk. Whoever specified their C&C truck and services should have been aware of likely data usage, and what could happen if they tried to use a capped service. It should be an object lesson in how not to do disaster planning. 5G will just allow users to hit their caps faster.
