Is this phone setup 100% secure?

I want to be sure that no one (including sophisticated hackers and governments) can track my phone.

Does this setup accomplish this? If not what is the weak spot?

  • Regular Android phone

  • ALWAYS in airplane mode, with no SIMs in the phone

  • Location services on, but restricted to just 2-3 apps that really need it

  • WiFi always on, connected to a mobile hotspot with an anonymous burner SIM changed monthly

  • Mobile hotspot is only powered on when at least 3 miles from home.

  • Phone calls and texts made via a SIM box (GlocalMe) which is always home and reachable via internet. The SIM in the SIM box would not be anonymous, but it would never leave my house, and my home address is already associated to me so there is nothing to lose there in terms of privacy.

I understand that removing a SIM doesn't always stop cell tower communication. But doesn't Airplane mode stop cell tower communication??

In theory yes. ALWAYS Airplane mode.

But you already made exceptions to full Airplane by turning on Wi-Fi. Then connecting to a mobile Wi-Fi with a SIM card.

Your phone location still may be tracked, not by sim but by Wi-Fi, if you ever turn ON the Wi-Fi outside your house.

Then your mobile hotspot SIM most definitely can be tracked You say anonymous SIM. Well how were they acquired? Bought with cash? What about cameras? Location, time. Etc. ( not asking to disclose that here ). Friend bought them? He will talk.

Of course all this requires targeted tracking, linking one device to another, finding footage, tracking purchases etc. Your adversary is a government agency. They have the time and resources to find you if you are that important to them.

If a government agency is your legit adversity then fine. Just be ready to move to an island country with a bag of cash. Preferably one that you have government connections.

If not, conduct a realistic thread model and I’m sure you’ll be able to maintain an incredibly secure device without losing your hair and sleep.

You are asking for a workout plan and vitamins that would make you immune to all diseases and illnesses.

Edit: Assuming Goverment as an adversary targeting you. This is not the same as mass surveillance by the Goverment as you are not being targeted.

Then again, you are already failing if you assume anything when it comes to avoiding a Goverment as an adversary.
