What do you mean by "number and number"?

Due to the different business contents in different provinces, you can call local 10086 for consultation. Taking Henan as an example, "Heduo" service can add up to three sub-numbers on the basis of customers' existing mobile phone numbers without changing phones or cards, so as to meet the needs of customers for voice communication and short message communication with different people using different numbers. At the same time, there is no need to carry multiple mobile phones. Customers can set the on/off status of an auxiliary number in real time/regularly, so as to isolate the communication circle, protect privacy and not be disturbed.

Main number: refers to the customer's original mobile phone number, and the main number has the corresponding SIM card entity.

Secondary number: including virtual secondary number and entity secondary number.

(1) Virtual sub-number: refers to the customer applying for a new number as a sub-number through multi-number service, and the virtual sub-number has no SIM card entity. After the customer has applied for the selected sub-number, he can't go to the business hall to apply for generating a SIM card or a replacement card from the virtual sub-number. The virtual secondary number has no business password, and only supports the functions of sending and receiving short messages, making/receiving calls, receiving multimedia messages, etc. Temporarily unable to open value-added services (if the sub-number opens value-added services, it may be shut down and cannot be used normally).

(2) Entity secondary number (temporarily deactivated): refers to the fact that customers bind their existing numbers as secondary numbers, and the entity secondary numbers have corresponding SIM card entities. The application scope of entity sub-number: ordinary individual customers such as GSM, M-Zone and Shenzhouxing brand, excluding special numbers such as random bank and Internet of Things that do not have voice communication function.

Note: 1, the virtual sub-number can't open the intelligent network service, but the entity sub-number can open the intelligent network service.
