I did some more testing with Mobian (bookworm) & Verizon today. I do have hotspot service on my plan, though my last successful use of it was several months ago with my old flip-phone so that's something that warrants follow-up.
Tethering seems to be basically just a NAT/forwarding scheme. I don't think there's anything new or Mobian-specific or Pinephone-specific here so it seems like it should Just Work.
Test #1: Tethering through wifi instead of cell connection worked perfect.
Test #2: Used tcpdump to capture packets when tethering through cell and using wget to retrieve a single html file (via https). There aren't any unusual delays in the packet exchange. I see the transfer start and I get almost 5000 bytes then responses from the cell connection just stop (for this transfer).
I'm no TCP/IP expert but I don't see how Verizon could know which packets were forwarded. I see no difference in tcpdump output for forwarded versus non-forwarded packets but maybe there's something tcpdump isn't showing. More research needed.
