Live device-identity event stream from working mobile networks: every attach or registration triggers an IMEI verification, producing IMEI-to-IMSI-to-MSISDN pairing records and — the genuinely rare part — device-change events, i.e. the timestamped moment a subscriber's IMSI moves from one IMEI to another.
