GrapheneOS Thank you for the helpful explanation.
If a SIM/eSIM card is not currently on the phone, can apps see the country of the last used SIM/eSIM card?
If no SIM/eSIM card was ever inserted/installed on the phone, can apps see any country, e.g. where a phone was purchased?
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

locked is this also standard in ios?
I don't know.
locked The only way to stop this is to not insert a sim card on the phone correct or always remain in airplane mode?
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 can test a few scenarios re: SIM card country code and report back...
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
redfoxjumper
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?
DeletedUser115 where were you texting the country detected thing?
redfoxjumper I don't want to put all this effort for a reddit account but I'm just puzzled to how and where is reddit getting info from?
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 I tested using WhatsApp on Pixel phones with GOS.
I don't use it myself. OP wanted a fix, I provided one
O
DeletedUser115 did you use a VPN too? I'll update with a reply if I ever find a solution for this
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.
