What about meter diagnostics? "Cut off" means "cut off"; what if the utility needs the capability of remote snapshotting the memory or current firmware rev of a meter? (Having done multiple smart meter security review projects: this is not a crazy notion).

Yes, fellow geek, there will be some number that represents the maximum amount of bandwidth that might ever be used to diagnose a faulty meter. How much would it cost to figure that out? Again: weigh that against the business benefit of doing so.

The person who abused the meter SIM did not accidentally do so.
