What's the use of moving the secondary card?

The universal secondary card is a mobile one-card multi-number service. On the basis of the main card, two sub-numbers have been opened, both of which can send messages by phone, and also support others to send messages and call the sub-numbers. All expenses are paid by the main card.

After the binding relationship between the primary card and the secondary card is established, it will take effect immediately in the current month. After taking effect, the universal secondary card can share the traffic, voice, SMS and MMS resources in the main card package.

The sharing rule of universal secondary card is to use its own resources first, and then use the main card resources after its own resources are exhausted. The traffic sharing rules of the universal secondary card are consistent with "sharing with family", and the international/Hong Kong, Macao and Taiwan voice packages, international/Hong Kong, Macao and Taiwan short MMS packages and international/Hong Kong, Macao and Taiwan traffic resources handled by the main card customers cannot be shared.
