Do China Mobile and Duohao, Entity Subnumber and Virtual Subnumber charge monthly rent? Do I have to pay extra for the physical card?

The universal secondary card is a mobile one-card multi-number service. On the basis of the main card, four sub-numbers have been opened, all of which can make phone calls and send short messages, and all of which support others to send short messages and make phone calls to the sub-numbers.

Different from ordinary mobile phone cards, the "universal secondary card" must be bound and activated with the main card before it can be used. After binding, all the expenses of the secondary card are paid by the main card, and you can enjoy the internet traffic and call minutes with the main card. In other words, after handling the "universal secondary card", there will be one more SIM card and one more mobile phone number to realize "multi-card number", thus meeting the internet and communication needs of many intelligent terminals of current users.

As the regulations in different provinces are slightly different, it is recommended that you call the mobile business hall or 10086 for details.
