The main card of the telecom card is me, and the auxiliary card is someone else. Which card should be notified if there is an epidemic crossing the track?

There are two travel codes between the main card and the auxiliary card, which do not affect each other. The National Government Platform Center uses big data to screen and locate the mobile phone trajectory. The movement trajectories of the main card and the auxiliary card are not exactly the same. The big data filtering for locating two different signal sources will not be affected and can be used with confidence.

Primary and secondary cards mean that China Telecom provides users with a primary card and a secondary card at the same time. The primary and secondary cards realize combined payment, with the primary card as the payment account. When the primary card user selects the basic package, the secondary card user can share the voice, SMS, MMS, data stream and WiFi duration in the primary card basic package. The unified package implemented by the main and secondary cards exceeds the tariff standard, and local mutual discount is provided between the main and secondary cards.
