Secondary card consumption is paid by the main card, so the secondary card does not need to recharge the phone fee. According to the official website of China Mobile, its main and secondary card business is called \"and multiple number\". That is, if the user does not change the mobile phone or add a SIM card, multiple (up to three) mobile phone numbers can be added to the original mobile phone number as the secondary number. Since the secondary number is no physical chip, there is no need for multiple mobile phones or multiple card slots, and the monthly communication fee is recorded under the main number package, which only requires a monthly functional fee of 5 yuan. More importantly, do not have a main number to register various platforms, to a large extent can avoid phone harassment. But it can only be used by yourself, if you want to share a package with your family, you have to re-understand other tariff package business.

2. In addition to the phone fee, the sub-card may also need to pay some other fees, such as card opening fee, monthly management fee, etc. 3. Some operators will also provide free sub-card services, but it should be noted that this free sub-card usually can only use a limited credit limit and traffic, and you still need to pay extra fees after exceeding the limit.
The secondary card needs to pay the phone charge.

2. The secondary card is opened by the main card, which is only convenient for different family members to communicate and share a more economical and special service. 3. Although this privilege does not allow users to fully enjoy the service of free calls and data, the additional fee portion is cheaper compared to the main card.
