SignalTrace “links devices that regularly travel together, correlating them to license plate.” It is a surveillance product that will sweep up and add all sorts of Bluetooth and other data to license plate readers, linking specific devices—and people—to cars.
Pretty sure I can’t use VoWiFi without at least a sim card. How are you going to do that without carrier tracking?
Or are you implying I should be a recluse who can’t be reached via phone?
I’ve gone the route of setting up my own XMPP server, using jmp.chat to get a new mobile number, and using Cheogram as my client. Works really well for my alt OS phone. You can use Cheogram, Conversations, Snikket, Jabber, etc. You won’t be able to use VoLTE or RCS, but I’ve invited friends to my server instance and just tell them it’s a new chat app better than Signal so it has OMEMO e2ee, but you can also text regular phones numbers, too.
