They would probably use a low cost IoT plan, which (without volume discount) is something like $1/mo and a few cents per MB. So they may be able to send content ID info or conversation transcripts, but video would be too expensive unless the user pays.

GPS is probably unnecessary since mobile phones are constantly mapping out WLANs. You can get a decent approximation of GPS with just a wireless scan in most places.

I saw a previous conversation here where someone said they were able to “repurpose” a similar IoT modem to get some free data, but the modern chips are soldered on and tightly integrated, so it would be harder to reuse unless you get root on the device. I think they use eSIMs stored in a secure element in the CPU.
