I run my #smartphone (#Pinephone with #Mobian OS) without a #SIM. That prevents #locationTracking through the #phone network.
My SIM is always at home in a USB modem connected to an SBC. That way I can receive and send #SMS using an #XMPP gateway, #sms4you.
If my #healthInsurance company ever gets my #location data, my contribution will skyrocket, as they will classify me as a 24×7 #couchPotato, worst lack of exercise ever.
