    IMEI/IMSI are collected (and immediately linked, hence deanonymized even if SIM was inserted only once) by cell tower operators. Just not bring your device, period.

      Yeah, I agree with that personally, but realistically, “your phone was near a place” is not the same as “you were involved”. If they hijack a phone onto a Stingray, they can get way more info than just IMEI.

        Think long term movement patterns, correlations with others such, anomaly detection.
