It’s quite possible that even with the SIM card removed, it’s still actively ending up in cell tower logs. At least here in the United States, if you dial 911 from any device, no matter whether it has a SIM card installed and no matter whether it has service or not, 911 is supposed to be able to answer, which means that it must be able to talk to the cell phone towers even without a SIM card installed. You might be able to avoid that by keeping it on airplane mode, but there’s no guarantee of that.
Yeah, I don’t have a good answer for that.
