Hi. I'm very new to GOS and relatively new to digital privacy in general.
I have an active eSim in the Owner profile and a second user profile. This occurred while I had data roaming turned off. All sim permissions for the second profile are turned off.
I downloaded telegram on the second profile while using an always on VPN and data roaming turned off. I opened telegram and when prompted to add a phone number, my Owner profile Sim number was pre-filled. I have never used telegram on this phone before.
I guess I thought this kind of information would be partitioned between the Owner and other users, but I guess I misunderstood this. Frankly, I don't even know if it matters, but it did surprise me.
How can I prevent apps from knowing information from the Owner profile, or is my phone number impossible to hide from third party apps across all users?
