This is something I’ve been thinking about for a while. I’ve decided to get a Pixel with GrapheneOS as my next phone and I’m trying to decide the pros and cons of putting a SIM card in it. Convenience vs privacy, public wifi with a VPN vs using phone data, etc.
I can’t get a SIM card where I live without ID and I’m looking to reduce being tracked as much as possible. Does anyone else do the same thing?


Not having a SIM-Card in your phone is like having a tank without a main gun - it drives, but it can’t really do what it’s supposed to do. I don’t think that it’s a good idea. Also, not having a SIM-Card doesn’t make you invisible - only airplane mode really does that. Without some kind of network connectivity, you have an expensive, glorified brick that can make photos, play games and lets you listen to offline music.
Also, I’m wondering what exactly you’re trying to achive. Get a private OS like graphene, don’t install any google services, have anti-tracking protection installed into the browser (or use a safe and sane browser by default) and you’re good.
Not having a SIM doesn’t do anything for you except hiding from your carrier, however, if your threat model involves you being worried by being tracked by your carrier (and by extension, the feds), you’re in really hot water already and you’re probably better off with detaching yourself from the modern world.
