It would be best if done on a burner with a different IMEI & IMSI while also not at a place related to where you frequent. The FBI (who now has fewer resources than ICE) were using facial recognition and cell phone data to identify large groups of the opposition not too long ago. It wouldn’t be a stretch to think ICE is going to do the same.
Since this news is coming from CBS i’d just as likely think it was price-gouging.
