you're kind of giving me a blank slate to talk here so let me hit the biggest point that is tangential to this conversation.
the easiest point for me to make is that if, on your phone, you bought your SIM card (and attached phone number) with payment info that can be tracked to your bank and your real name, your location is compromised whenever that card is online. this is something that the vast majority of privacy enthusiasts either neglect due to lack of knowledge, or cannot afford to remove from their threat profile due to the pervasiveness of cell networks in day to day life.
The most recent example i can give of this being necessary to consider in your privacy posture: In the US, ICE is using this combination of personal information and compromised locations to focus their efforts in neighborhoods with a primarily minority population.
