More than a hundred years have passed, and the history of human communication is still evolving. Since two cans and a rope, human beings have been exploring how to use tools for remote communication; Although we have entered the era of mobile Internet, and the information interaction between people is more abundant, the traditional communication method is fast, simple, and not limited by time and space, that is, telephone and short message are still the interaction subjects in our life, and it has the universality that cannot be guaranteed by QQ, WeChat and other communication platforms (Not limited by mobile phone models and user habits) Timeliness and high delivery (The ability to get key information in time) 。

As the basis of communication methods, it brings many conveniences as well as many troubles; Our life is not divided into work and personal. If the boss wants to find you, he can find you at any time. So can the customer. It's nominally off work, but you have to be on call 24 hours a day, ready to be dispatched; To hide a card, you can escape his or her "surveillance" at home (I didn't do that, ha ha); In order to effectively distinguish different social groups, we have to use multiple mobile phone cards to meet the needs of work and life. Unfortunately, the iPhone and some Android phones that have attracted much attention still only support a single card, which has greatly affected the convenience; However, today let's solve all the difficulties of single card mobile phone users with a "black technology" - "dual sharing account" that meets the future of communication.

"Black Technology" Experience of "Double Sharing Account"

This "black technology" dual account smart hardware for future communication is actually a small box with the size of a thumb and only 6.3 grams. It can be selected in black or white. It is equipped with a lithium battery, a Micro SIM slot and a SIM card case. It uses a MicroUSB interface for charging. It is equipped with a blue tooth pairing button and a lanyard port. The other end of the attached lanyard is a dust plug. If the headset is not used at ordinary times, We can also insert it into the iPhone headphone hole as a decoration; According to the official introduction, this compact intelligent hardware has also been jointly invested by China Unicom Venture Capital and Ten Party Venture Capital under China Unicom. From the investment background, we can see that this "black technology" that changes the future communication method is actually supported by operators.

⑴       Delicate and simple, small and exquisite

The overall shape of "Double Sharing Number" is small and cute. The body is made of hard plastic material, with smooth and soft corners and strong texture; The Bluetooth switch button on the front of the fuselage is integrated with the indicator light, and there will be light prompts when it is powered on or turned on. However, the light is weak in the strong light environment, and it is often blocked by fingers when it is turned on.

⑵     Rich interfaces and lasting energy

Micro USB interface charging mode with strong versatility liberates users to the greatest extent; Charging anytime, anywhere, whether it is a computer or a mobile power supply or other charging devices can easily charge the "dual account"; It has a built-in 55mAhR lithium battery, which can provide 15 days of use time for the "double sharing account" after half an hour of charging. Note that 15 days is the use time. As for standby, it is self-evident that it will last at least 35 days!

⑶       Warm design, easy to carry

In order to improve the user experience and better solve the problem of carrying, in addition to its small size and light weight, the "dual account" has also designed a lanyard, which matches the attached headset jack lanyard. It can be hung on the phone protective case, key chain and other decorations, or put into a wallet or directly into the lanyard to access the headset jack, similar to the earplug decorations of previous mobile phones; It should be reminded that when installing the lanyard, it should be noted that the lanyard is not directly inserted, but directly inserted after opening the rear cover.

Due to its small size, the "double sharing number" is extremely portable, not only suitable for hanging ropes, but also can be placed on key chains, wallets and other accessories.

⑷       Advanced technology and powerful functions

Open the back cover of the "Double Enjoyment Number" from the middle seam, we can see the built-in SIM card slot. The "Double Enjoyment Number" can be inserted into a MicroSIM card. If you are a NanoSIM card user, you can also easily restore the size of the Micro SIM card with the card sleeve provided with the machine.

The "dual sharing account" has the WiFi Calling function of voice and SMS transmission based on the Internet. It can provide communication services in areas that cannot be covered by mobile phone signals, help operators greatly reduce the cost of network blinding, and use WiFi environment to provide users with good communication services; That is to say, when the SIM card has no signal, we can also connect or make a call through the Wi Fi network.

Good news for frequent overseas travel and overseas users, the "dual account" not only supports dual cards and dual stays, but also enjoys the communication function of international roaming free. Put the local card outside Shanghai in the mobile phone and the domestic number in the "double sharing number". The user's use of phone and SMS is exactly the same as that in China, and will not incur huge roaming costs. Click "like" to this "black technology". In the future, before going abroad, there is no need to say: "I have gone abroad, my mobile phone is disabled, and something is wrong with QQ".

⑸       Integrated application and IP based communication data

The number life has developed a dedicated APP for the "dual sharing number" to support its use. Unlike Apple Peel and Internet calling software, the "dual sharing number" uses SIM card authentication and communication sharing mechanism. The hardware part is responsible for SIM card authentication and authentication, and the dedicated APP is responsible for communication functions; The built-in "Xinxin" chip can transmit SIM card information to the corresponding mobile phone APP through Bluetooth, and then transmit it to the operator server through the mobile phone's IP channel, so as to complete a complete call and information process. To put it bluntly, you can regard it as a part of the mobile phone and combine it with the APP to form a complete mobile phone.

Practical APP experience close to the system communication UI

⑴       Simple and refreshing interface

Scan the code or APP store to search and download by itself: Double account APP, and enter the experience. From the interface, we can see that the integration of APP and mobile phone UI is excellent, almost similar to the system UI, and can't have any too much decoration and complex operation.

As long as you select the SIM card in the box, enter the phone number in the box and click the pairing connection on the right, you can complete the verification and registration with one key. Some regrets are that the current "dual account" smart hardware only supports China Mobile/China Unicom SIM cards. For telecom card users, it is better to wait for the number life to be opened as soon as possible.

⑵       Fast connection and simple operation

Click to register the user. Here, we load a Xiaomi Mobile 4G phone card into the "Double Sharing ID" in advance, press and hold to turn on the red blue flashing mode, then enter the phone number in the "Double Sharing ID" in the registration, select the SIM card in the box, click the refresh button on the right, the device will quickly pair and connect through Bluetooth, and the verification is successful; When the "Dual ID" is perfectly connected to the mobile phone, you can see the phone card number, the "Dual ID" hardware status, system settings and version information on the "My" home page.

⑶       Same control mode as dual card dual standby mobile phone

The dialing interface is similar to the common mobile phone UI. After a successful small activation login, the information is the same as the call. However, when you enter the phone number and click the dialing button, there will be two choices: SIM card 1 and SIM card 2. SIM card 1 is the phone card in the mobile phone, and SIM card 2 is the phone card in the "shared number". Here we naturally choose SIM card 2 to make a call.

In the call experience, the time of making a call is longer than that of making a direct call on a normal mobile phone, and there is no message function such as home location display ， The handling of incoming calls is not so ideal. The "dual sharing number" cannot display the details of the number when calling, and the contact in the address book also displays an unknown number when calling. Maybe it is because of the problem of the test card operator. This user needs to experience it personally; As for call quality, call signal and stability, they are quite good, basically equivalent to mobile phone calls; For some minor problems, the "siege division" of APP should continue to focus on optimization.

Summary

In the past, in order to separate work and privacy, we generally used two mobile phones, and suffered from the troubles brought by two mobile phones; Now, the "dual account" provides you with convenient communication services, free from the restrictions of network system, and free to chat at any time; In the future, the "dual account" will not only realize free calls and improve your user experience, but also will continue to introduce new functions and provide various life convenience services related to the second number; As a high-tech and intelligent hardware product with practical functions, the "dual sharing number" enables single card mobile phones to also realize the function of dual cards, Although there are still many shortcomings in call access speed and APP, But how can such a charming "black technology" not be favored by you!

If you like this super attractive "black technology" intelligent hardware as much as I do, remember to pay attention to December 28, when the "dual sharing account" will debut in JD crowdfunding.
