Description

dual card dual standby mobile phone

technical field

The utility model relates to the field of novel mobile phones, in particular to a mobile phone with dual-card, dual-standby and dual-call functions.

Background technique

As a communication tool, mobile phones have widely entered people's lives. With the development of technology, mobile phones have more and more functions. People's requirements for mobile phone functions are also getting higher and higher.

In order to meet the needs of their business, some people need to have several mobile phone numbers at the same time, and need to carry several mobile phones. The price of mobile phones is not cheap, and it is very inconvenient to carry several mobile phones. Without solving this problem, the industry has developed a mobile phone with dual-card dual-standby function. This dual-card dual-standby mobile phone can install two cards at the same time, and the two cards can also be on standby at the same time. When one of the cards is called , the user can choose to answer the call. When two cards are called at the same time, the user can choose to answer one of them. When one of the cards is calling and the other card is called, the user can choose to end the current call and start the call of the other card, or directly hang up the call of the other card.

Yet because the user can not carry out the conversation of two cards at the same time, when the user uses a card to carry out the conversation, if another card is called because of important matter, the user can only be forced to hang up at this moment, can cause important event delay.
