If I have 2 phones running Graphene OS. Phone 1 will have no sim card, Phone 2 will have a sim card. I will carry them together, Phone 1 will be for public, common things, e.g., co-workers/employers giving them that number, and Phone 2 for personal/online life with no sim and only using over WiFi which is of course much safer. Would having the phone with the SIM card next to my other regular devices allow it to be linked back to me?
And would hotspotting off of Phone 2 using Phone 1 if Phone 2 is using cellular data comprise security?
My guess is yes. My understanding is that hotspots use cellular data and are not routed through a VPN. I am sure someone here with more knowledge can correct or confirm that.
I tend to think there is just to much oppurtunity for these phones to be eventually linked if you are carrying them together. This is assuming the phones weren’t purchased in a way that already links them together.
This is correct, tethered hotspot connected devices and to my understanding Wi-Fi to tether applies too, do not get routed to the VPN
and before anyone asks yes I did test that theory so I wouldn’t be called crazy again.
Some if not just orbot does have the option to Open the connection to all peers
But in my testing this doesn’t seem to be effective at all, IP Doesn’t change on the connected tethered device but I still wanted to show it just in case it was or there is and I’m missing something but still.
Curiously, I was thinking of the same set up as you in the mid-term.
Yes. Edward Snowdens says so in this interview (I don’t remember at what moment).
What I think I may do in the future is to keep at home the phone with a SIM card (with a normal operator, with my real name). And to use use a data-only SIM from SMSPool for my main phone (but to put it in airplane mode most of the time, and to not disable it in places which could identify me).
