face Android The mobile phone has its own dual card and dual standby "recklessness", iPhone But always insist on single card. This made some of the "Rose Gold" fans have deep "grievances". If they have two cards and two standby needs, they have to wear apple peel or take another mobile phone. The shortcomings of this solution are also obvious, thick, heavy, troublesome and costly.

However, last week, the tail got a "Double Sharing Number" product produced by NumberLife. Its biggest feature is that the second card can be stored on the thumb body, which can be combined with Bluetooth and wireless network, iPhone Complete call and SMS functions can be realized without prison break or hardware modification.

iPhone Users can also simply realize double cards and double standby, and open their lives AB The window in front of me.

The package of "Shuangxiang" is simple and simple. It is directly packaged in soft bags, but it is well sealed. When opened, it found that there is still a layer of foam protective layer inside, so there is no doubt about its transportation safety. The specific parameters can be known on the packaging bag, and Bluetooth can be used four ; size is 46.1mm*25.mm*7.5mm , the size of thumb is very vivid; Weight is six point eight Grams, almost as heavy as a one dollar coin; Power capacity is 55mAh 。

The accessories are considered carefully. The card holder is convenient to pick up the card. The earphone plug can hang the "double number" on the phone or the key chain. The card holder can adapt to different cards. Because the product is very simple, the manual mainly introduces APP It is also easy to use.

There is a Bluetooth pairing button on the main body of the "Dual Sharing ID", which can be connected to the mobile phone by pressing and holding. The side charging port adopts the standard Microusb Interface, you can use the phone charger directly, so there is no standard charging line in the accessories.

The "Double Enjoyment Number" can be opened without additional tools by directly pressing on the notch on the side. Of course, the interior is also very simple SIM Card slot, install the second card to complete the hardware part. This physical hardware is a simple SIM The card authentication and authentication device has no communication module, so it is very compact.

The communication function of "dual sharing account" is through the mobile phone APP To achieve. According to relevant data, its working principle is to read through the exclusive chip "signal core" on the hardware SIM Authentication information, and then transmitted to the mobile phone through Bluetooth APP ， APP Re adoption IP The channel is transmitted to the operator's server, and the operator sends back information through the Internet to APP , realizing full call and SMS functions. The tail is based on IP Technological innovation is the product of combining Internet communication and operator communication.

Bluetooth connection of "dual sharing number", and APP There is a bootstrap for the registration and binding process of the. Please kindly remind me that the second card should not use the telecom card. If the support has not been opened for the time being, the registration will fail, either China Mobile or China Unicom.

APP Of UI The level is clear and concise. It is divided into three functional areas: "communication, message, and I". You can make calls, SMS operations, and some settings. The most important thing is that it can not only provide communication, but also mark calls, text messages and block blacklists, which plays a great role in improving the user experience.

After testing, the "dual sharing number" has no problem in realizing the communication function, and its operation interaction is similar to that of most dual card dual standby phones. When we make a call, we will be prompted which one to use SIM When the network signal is good, the call quality is similar to that of normal communication, and there is no obvious difference. However, let me remind you that although it is based on the Internet, the call charges are still normal.

The power consumption of the "dual sharing account" is very small, and the official promotion is charging thirty Minutes, available fifteen Days. In this regard, it has been used for more than a week and is still in use.

Finally, some feelings. After using this thumb device for some time, I love it. It should be said that at the low price of 50 or 60 yuan, the "Double Enjoyment Number" is iPhone The user provides a compact and convenient solution that can be used as long as there is a network. The interaction is also as close as possible to the use habits of dual card users. Next, it is suggested that the "dual account" can support the telecom network, further expand the functions and UI Interaction, such as adding traffic support function on the basis of communication function, which makes it easier for some users to meet the traffic demand of dual cards. In terms of hardware, it is further flattened. Although it can now be put on the body or hung on the key or wallet, it should be more convenient if it is flattened and pasted directly on the back of the phone book.
