Before work on T-box serial registration, digital-service and delivery teams should name the reviewer and closure owner. Each approval of T-box serial registration should cite the same VIN, account, software version, and service country for traceability. Destination network-access and device-identification requirements for T-box serial registration are set by the local communications authority and licensed bodies, unless the applicable contract provides otherwise. For a practical way to organize order evidence, see this vehicle-import FAQ. Once the supplier provides the service-coverage list, the account or version record, and the local test result, the dealer should still run the activation and sign-out tests for T-box serial registration on a local phone or a test account. Flag anything in T-box serial registration that cannot be delivered in the sales material, and close the account or data issue before handover.
