I have been using a phone this way since phones came out, because the device will track you. His phone (light) will also track, since it still uses IMEI and SIM data which can be triangulated by tower access (the tracking we should be mainly concerned about). So, you will need to keep your distance from that device too.
I recommend everyone watch Rob Braxman on UghTuub, Odysee, or Rumble. He breaks down which parts of surveillance are a threat to the average person, how much of a threat, WHY it is or is not as much of a threat, and what can and can't be done about it.
