What does China Mobile Universal Card mean?

The universal secondary card has a separate mobile phone number, which is different from the main card number, but it can enjoy the voice and unlimited traffic of the main card at the expense of the main card. Prompt: The main card fee should be "98-988 RMB National Unlimited Package" or "100-990 yuan National Unlimited Package", or participate in the "Grateful Feedback, Package Discount" activity, and handle the unlimited card set for 100 RMB and above, and the main card customer will open a new universal secondary card with the same certificate.
