One number is divided into two cards. Do I have to pay for texting?

Master card and slave card have the following two situations:

1, a number is divided into two cards, but the secondary card can only be used for data services such as internet access, and SMS and phone calls cannot be used. In addition to making full use of the package traffic, the main card and the auxiliary card are charged in a unified way, and the two cards do not interfere with each other.

2, in a package, there are two different numbers, two numbers * * * enjoy this package. The main card pays the fee, and the fee of the auxiliary card is included in the package of the main card, and the main and auxiliary cards realize combined payment. The primary card users choose the basic package, and the secondary card users can * * * enjoy the benefits of voice, SMS, MMS, data flow, WiFi duration, prepaid phone bill return or free phone bill in the primary card basic package.

Extended data:

The difference between the primary card and the secondary card.

1. At present, the distinction between the primary card and the secondary card is an old concept, because in the early days, the primary card can take traffic and operation, while the secondary card can only continue the inherent understanding of 2G calls.

2. ARPU value from the operator. Generally, the ASROU value of the main card of mobile phone is higher, so the operators who occupy the card will have more rights to use the main card. These are not the primary and secondary cards mentioned by operators, but the primary and secondary card slots defined according to users' habits.

3. Some softwares want to be downloaded, and the default mobile phone number is generally on the main card. So putting the main card on the main card will make you much more convenient.

4. In some global brand mobile phones, some dual cards are very different, and the permissions of the main and secondary cards are also very different, such as NFC-SIM cards. I think those international brand mobile phones can only be used normally if they are placed in the secondary card.

Sometimes the mobile phone signal of your main card is different from that of your secondary card, and there is little difference between the mobile phone card developed by operators and the main and secondary cards now.
