Background: We have deployed MAX devices based on Verizon and AT&T connections. Verizon (“unlimited”) limits hotspot/tethered (their terms) usage to 15GB/month/device.
I would expect that usage via a cellular router would count either fully as hotspot usage, or not t all.
As it turns out - Verizon counts some data usage as non-hotspot usage, and some as hotspot usage. For a particular subscription the fraction counted as non-hotspot can go as high as 30% or as low as 0% per week.
Question: Does anybody know (or care to speculate) how Verizon decides whether transmissions should count as one or the other?
Further background: The device we have been tracking is a MAX Transit Duo (with one Verizon and one AT&T card) with a PepVPN to the home office (a Balance 380). Only traffic bound for the intranet are routed to the VPN, the rest connects directly with the Internet.
