DeletedUser115 I'm brain storming too. Do you think apps have the access to the phones IMEI number? I'll keep this forum updated if I find a way

    GrapheneOS does having the same app on the Main profile and the other profile are some of connected? I'm new to all this and assume most of the questions have already been answered. Where can I go and read about this?

      de0u they just have a really bad spam filter and I can't do anything about it

      de0u is this also standard in ios? The only way to stop this is to not insert a sim card on the phone correct or always remain in airplane mode? What happens if you turn airplane mode on and off? Does your country code remain available to apps when airplane mode is turned back on?

        I don't know.

        Again, I don't know. I don't have a use case for concealing my physical country location or characteristics of my SIM card from privacy-invasive apps on my phone because I don't have privacy-invasive apps on my phone. The question of whether SIM characteristics are available in airplane mode is interesting, but I don't know.

        I did a few tests:

        Phone that never had a SIM/eSIM: country not detected

        Phone that had a SIM before but now doesn't have one: country not detected

        Phone with a SIM card, airplane mode on: country detected

        Phone with a SIM card, airplane mode off: country detected

        So it looks like only the current SIM is used and airplane mode doesn't have any effect on country detection.

          There is a shizuku plugin that lets you change the country code. Don't remember the name but if you google how to unlock pixel temperature unlock in any country it should come up

            Use of shizuku is not recommended. Enabling any adb connection opens up a big security hole. Providing apps on a device access to adb has further troubling security implications.
            Theres numerous things that can be changed via adb which have a huge impact. Its also possible to break the OS in unexpected ways which can then be difficult to debug.

              DeletedUser115 thank you for doing the test. I tried doing it on my laptop in an virutal box using a Tor browser and it still detected my country. I have no clue how this is happening. I'm using an VPN then Tor browser. Is it my VPN? But if I used Tor shouldn't that exclude all possibilities?

                NewGrapher77 If you created an account in Reddit app on your phone with a SIM card the app can know the country from the SIM card.

                If you later use this same account on a desktop over Tor, the country is already associated with that account.

                NewGrapher77 Yes, in all tests I used a VPN with a server in a country not matching the country of SIM card or the country where the phone was purchased.

                a month later

                DeletedUser115 Thank you for the test results.

                GrapheneOS allows for a physical SIM and eSIM to be toggled off even while the SIM is still installed. Does anyone know if the country code is still accessible when a SIM is toggled off and airplane mode is on?
