Cell tower signal can be used to triangulate you as long as the SIM card is powered. Do you trust your phone not to keep the SIM powered, even when “off”?
WiFi and Bluetooth isn’t even fully off when you disable it on stock Android unless you specifically tell it not to do “background scanning”. This option is not displayed in the WiFi/BT settings, you have to visit the location services and turn it off there.
Even then, do you trust that setting to actually be off?

Ah that’s a solved issue. Process and/or store whatever you’re collecting on device until signal returns, then upload. No problem.

I don’t trust my tech much at all, hence the faraday bag.
