@ddipaola Yeah that's always an option. I could just pull the SIM card out of my Pixel XL or use my wife's old Nexus 5X on which I've already installed #LineageOS (and already doesn't have a SIM card).
Many Android apps tend to be heavily dependent on network access, but I could test it out. If there were an #OpenSource #Android #APRS application, that would go a long way toward convincing me that's the right solution.
