I am brand new to Grapheneos and had a question about the hotspot feature. When connecting either of my computers using Linux Mint via wifi hotspot they don't use the hotspot data from my wireless plan (MetroPCS).
For clarification, I get "unlimited" data, and 10Gig of "hotspot" data. I've transferred several gigs and my "hotspot" data is still at zero, but my "unlimited" data is being used.
Am I getting free hotspot? I have no idea the technical methods which my carrier verifies if data is being forwarded to another machine.
