Nowadays, mobile phones have become an indispensable part of people's work and life. In many cases, one mobile phone number is far from meeting the diversity of people's needs. Using dual card and dual standby mobile phones is one way, but many high-end mobile phones, such as iPhone Samsung S6 edge It is obviously not the best solution to only support a single card and carry two mobile phones with you. Just the synchronous update of the address book will drive people crazy.

"Number life - The emergence of "Double Sharing Account" is the birth of a perfect solution.

This evaluation is mainly divided into two aspects: appearance design and function use.

1、 Appearance design

one , Packaging

When I just got the express envelope of Shuangxiang number, it really surprised me. I felt that there were several pages of paper in the envelope. Open the envelope, and the orange package is in front of you.

          two Appearance

Take it in your hand, and enjoy it more seven No. 1 battery is still light.

II SIM Card installation

Open the double sharing account along the "rear cover opening slot" at the lower left corner of the double sharing account.

Then cover the back cover, and the installation is complete, simple.

Very simple, very simple, very simple.

3、 Function use

one . Download the "dual account" mobile phone first APP , installation, this process will not be repeated!

two , Turn on Bluetooth.

open APP At the same time, press the "Bluetooth pairing button" of the dual account.

Bluetooth pairing is complete, simple.

At this time, the status displayed by the dual account is "online".

In the notification bar of the mobile phone, the icon of dual number is also displayed.

Very simple, very simple, very simple.

  three , make a call

Open the dual account and click the green "Communication" icon.

The interfaces are as follows:  

Select a contact person to make a call.   Contacts not in the phone book can enter numbers through the dial.

The dial is sensitive, but there is still a fly in the ointment. First, the numbers of the number cannot be all displayed, and the last two digits can only be displayed as“ … ”； Second, pinyin association is not supported, and only numeric numbers can be entered.

 4 , Send SMS

Open the dual account and click the blue "message" icon.

In the above figure, the "Message" interface displays the system messages of the dual sharing number, and the "SMS" interface displays the incoming and outgoing SMS messages.

  Select a contact person to send SMS directly.

Use different colors to distinguish between messages.

Contacts not in the phone book need to click first   Mark, and then create a mobile phone number to send a short message.

The new SMS or message received by the dual account will be reminded on the "Message" icon and the mobile phone notification bar.

Through the above evaluation, we can be sure that the dual sharing account is very simple in voice call and SMS sending and receiving, which conforms to the operating habits of most people and can fully meet the basic needs of information communication and contact in work and life.

One thing to note is that the communication function, call record and SMS record of the dual account are independent of the communication function of the mobile phone itself, that is, the calls received and the SMS messages received or sent using the dual account are invisible in the call record or SMS function of the mobile phone, and vice versa.

  five 、 WiFi calling function  

WiFi calling Functions can be said to be a major feature of the dual sharing account. In the absence of mobile phone signals, as long as there is WIFI The network and dual sharing account are still the bridge for external communication.

Remove the built-in SIM Card, so that the phone is completely in a card free and signal free state, and connect the phone WIFI With the Internet, the dual account can still make calls and receive SMS messages.  

It's amazing!!

5、 Stability of Bluetooth connection

In the evaluation process, no matter the dual account and mobile phone are connected by a lanyard, or separated by a certain distance (such as in a computer bag, clothes pocket, drawer, etc.), or in different sports states (such as taking a bus, driving on the highway, etc.), the Bluetooth connection is still stable, and the voice call effect is very good, clear, coherent, and free of noise.

During the evaluation process, there were also cases where the dual sharing number was offline.

However, in case of the above phenomenon, there is no reminder in any form for the dual account, neither a prompt light nor any prompt in the mobile phone notification bar, but only a prompt appears in the "system message". This phenomenon is likely to cause missed calls or SMS, especially "unstable network connection" …… ”The prompt box of is always displayed after the phone number is dialed out.

It should be noted that the main mobile phones used in this evaluation are S6 edge When using the "Intelligent Manager" software of the system to optimize the memory, the dual shared ID will be forced to close without prompt.

Huawei MATE7 When the built-in "mobile phone butler" optimizes the memory, the corresponding prompt appears.

6、 Communication expenses

As for the working principle of dual account, the official explanation is: "dual account" adopts SIM The main functions of dual ID hardware are SIM Card authentication, while mobile phone APP Mainly communication function. Read by the built-in chip of the dual account SIM Card information, and then transferred to the mobile phone through Bluetooth APP , followed by APP Via mobile phone IP The channel is transmitted to the operator's server, and then the operator sends back the information through the Internet to APP To realize complete call and SMS functions.

In a nutshell, the dual account is connected via Bluetooth APP ， APP Upload the information to the server, and the server exchanges data with the telecommunications company. Calls and SMS use traffic.

To this end, the official recommendation of the dual account is that users open 4G Package, enjoy high-speed, accurate voice and SMS services.

In the above figure, the call location shown is Jinan, Shandong Province, because the Internet phone server of the dual account is in Jinan. There are detailed instructions in the help manual of the dual account.

7、 Endurance

The full charge time of the dual account is about thirty Minutes, working days for three consecutive days, APP The battery displayed is still full.

8、 Overview

This evaluation mainly uses the customized Samsung S6 edge mobile phone of China Telecom, and Unicom SIM card is included in the dual sharing account At present, the dual account only supports mobile and Unicom SIM cards, but can be used together with telco phones.

The dual account can fully meet the basic functions of "the second mobile phone", such as calling and SMS. In the process of use, it also maintains a good user experience, especially WiFi calling function can effectively increase the application range of dual sharing number. Compared with carrying two mobile phones, the dual sharing account is really lightweight, exquisite, and very convenient to use, without worrying about power, standby time and other issues.

At the same time, the dual account also has some problems, such as insufficient intelligent operation. The current version of mobile phones APP Only the most basic communication functions are available, and there is still much room for adjustment and improvement in function expansion.
