Live GSM tracking can provide remote alerts; a delivery reading shows only the condition at that moment. They answer different operational questions.

Decide whether route intervention is needed, check coverage and device power, and name who responds to alerts. Confirm from model instructions whether local logging continues without a connection.

In a pilot shipment, compare online alerts, local records and receipt checks. Do not treat a GSM alert as the only evidence; retain device, event and handoff records together.
