Double card and double waiting. Due to a special reason, a function that is extremely important to most Chinese users, how many fruit fans have changed their camp because of the iPhone's lack of double card and double waiting and can't stand the trouble of double guns. But perhaps this situation will be changed in the future. At present, there are two patent applications submitted by Apple in the State Intellectual Property Office, And this is exactly about double cards and double stays. According to the application submitted by Apple, its patent numbers are 2016101166075 and 2016100813788 respectively. One is the dual SIM network option, and the other is the power consumption reduction technology for dual SIM devices. Although it has not passed yet, it can also be seen that Apple will be equipped with the dual card dual standby function in future models. After all, almost all other brands in China except iPhone currently support the dual card dual standby function, and China is one of its important markets. I hope this function can be realized as soon as possible, and I believe that the resulting sales growth is also considerable.
