• I’m pretty sure the SIM still connects to cell towers even if you have mobile data deactivated

        Edit: on most phones it prevents the connection but there are still other ways to track like GPS

        • The GPS data will not be sent to the carrier, will it? And your phone will only be searched if they can tell its you in the first place. In which case you got caught physically there anyway.

          Also this no id thing is confusing to me. I guess its just american law. In many other countries, they just jail you until you tell them who you are.

      • If you have an iPhone you can go ahead and try Flight Mode right now. You’ll see that it disconnects from WiFi and disables cellular. NFC, Bluetooth and Wi-Fi stay powered on, Bluetooth stays active. Yes, latest iOS has Bluetooth tracking protection on by default (varies by country, illegal in some), but it is not completely safe. I’m not sure about NFC and Wi-Fi. If you power the phone off it is unlikely to turn off the radios - they are needed for “find my iPhone” and similar features on Google and Samsung Galaxy phones.

        Overall you can’t be confident that your phone does not reveal your location and identity to “law enforcement”, especially in places where police is well equipped to track you.
