Can the secondary mobile phone card read the SMS and MMS of the primary card?

1. The primary and secondary cards are only used for packages and fees * * *, and are used independently. The primary card can't view the messages sent and received by the secondary card.

2. For secondary cards, the main card often has more functions, such as MMS, but some mobile phone secondary cards do not have MMS.

3. When the primary card user chooses the basic package, the secondary card user can * * * enjoy the voice, SMS, MMS, data stream, WiFi duration, prepaid call back fee or free call fee in the primary card basic package.

The mobile secondary number has no physical chip, no need for multiple mobile phones and no need for multiple card slots. The monthly communication fee is recorded under the main package, and only the monthly 5 yuan function fee is required. More importantly, various platforms do not need to register a main number, which can largely avoid telephone harassment. But you can only use it yourself. If you want to share a package with your family, you have to re-understand other tariff package businesses.

The difference is that the supplementary cards of China Telecom and China Unicom are both calling cards with physical chips. According to official website, for the two operators, the secondary card fees are paid by the primary card, and the secondary card can also enjoy the traffic, voice and other contents in the primary card package. Moreover, the supplementary card can be taken out for home use alone, and can also be inserted into other electronic devices that support mobile phone cards.
