preface

When an iPhone user has multiple phone cards, the traditional approach is to buy an additional phone to hold the second card, or buy a new phone with dual cards and dual standby. Now the most fashionable way is ： Put a thumb sized Bluetooth box in your pocket!

Yes, this small box is called Double account , a magic weapon that allows your iPhone to have dual cards and dual standby.

packing

▼ The package of double sharing number is a palm sized yellow paper bag, Simple, eye-catching and environmentally friendly . Logo and color logo of double sharing number are printed on the front.

▼ The logo looks like two hands are pinched together, and the chamfer at the edge of the logo reminds me that these are actually two sim cards, emphasizing that "double cards and double waiting" means that two cards should be tightly held together.

▼ On the reverse side of the package are some simple introductions.

Unpack

▼ Tearing open the paper bag and looking inside, we can see that there is a layer of bubble paper inside, which can not only prevent falling and shockproof, but also improve the overall strength of the package.

▼ Take out everything from left to right Accessory bag, double sharing number equipment, instructions 。

▼ Included in the accessory package Nano sim card to micro sim card sleeve, sim card pin, earphone plug lanyard 。

▼ After reading the manual, we know that the function of dual card and dual standby needs to be realized through the official app. The instruction manual includes the function introduction of the dual sharing number and the setting method of the app with pictures and text, and also provides the QR code for users to scan and download the app. If you don't understand the manual, there is a thoughtful 24-hour service hotline waiting for you to call.

Equipment appearance

▼ My first feeling when I picked up the Shuangxiang account was that it was so Light and compact ! Let me want to play like a coin. Double account Dimensions: 46.1mm in length, 25.7mm in width, 7.5mm in thickness, 6.3g in weight, It's a little bigger than a one yuan coin. The shell is made of environment-friendly non-toxic PC material and ABS material by injection molding.

▼ One end of the dual sharing account is a lanyard, and the other end is a Micro USB charging hole. Most Android phones can be charged by the charging cable. In terms of endurance, the official statement is 15 days after fully charged 。

Installing the sim card

▼ Before installing the sim card, you need to open the back cover of the dual sharing number. It is very simple to open the back cover. Just insert the nail into the gap on one side and cut it open to easily separate the back cover.

▼ After separating the rear cover, I use the card pick-up pin in the accessory bag to remove the sim card from Xiaomi 3 (I may abandon my Ernai Xiaomi 3 from now on).

▼ The next step is to install the sim card into the dual account. The specific steps are as follows: 1. Push down the metal cover of the sim card slot to unlock and open the metal cover 2, put in the sim card 3 in the specified direction, close the metal cover and push up to lock it

Finally, close the back cover to complete the installation.

Download apps and bind phones

▼ My mobile phone is iPhone 5. After scanning the QR code on the manual, click the link provided in it to jump to the interface of the dual account client in the App Store.

▼ Open the app after downloading, Click "Login" and register . Here I use my iPhone's own phone number as my account to register.

▼ After entering the verification code, you can successfully register. Next, you need to bind the dual account with the app, as follows: 1. First, turn on the Bluetooth of the mobile phone, and enter the dual account setting interface in the app. 2. Long press the Bluetooth button on the dual account until it lights up. 3. Click to bind after the mobile phone finds the dual account

Call and SMS test

▼ First Telephone call test . Enter the dialing interface in the app, enter the number, and you will be able to select whether to dial with the primary card or the secondary card. Because my secondary card is a mobile card, calling 10086 is perfect. During the call, the blue light of the dual sharing number will be on, and it will be connected in a few seconds. The call quality was very clear, which surprised me. But there is also a regular sense of discontinuity. The sound pauses about every second, like cutting the sound into many segments, and then sending it in succession. This may be related to the principle of dual sharing number. I hope that the seamless connection of these voice segments can be better, so that the call will be more smooth. But now this situation will not affect normal calls.

▼ Telephone answering test . I used my home landline to call myself, and deliberately asked my mobile phone to lock the screen first. After the call is connected, the lock screen interface will pop up a reminder with a beautiful piano ring tone. (In the subsequent tests, two points need to be noted: 1. The phone still has ringing tones in mute mode! It was later discovered that because the ring tone and other music apps play songs on the same principle, and the iPhone ring tone volume and app volume are controlled separately, the iPhone needs to manually turn off the app volume to really mute. 2. After the app background completely exits, no calls can be made , and the Bluetooth box is about 20 meters away from the mobile phone, but the App will remind you that you are disconnected and let you reconnect the Bluetooth box, so it is better to take it with you when you go out.)

▼ SMS receiving test . The push can be received normally, and the app also has its own SMS interface.

▼ SMS sending test . Here I use the secondary card to send SMS to the main card. The SMS editing interface is simple and clean, and can be received quickly after sending.

So far, the phone and SMS have been tested, and the overall effect is satisfactory. Some minor shortcomings can also be tolerated. At least it is no problem to replace the Ernai machine! Another point is that all functions need mobile phone networking!

summary

After a week's use, I have to say that it would be great if the double sharing account could come to the world quickly. It definitely deserves it “ Ernai Machine Terminator ” Because it is light, compact and easy to operate, it is much easier to take it than taking an extra Xiaomi 3 to go out!

At the same time, I hope that the app of the dual account can be improved more stably and humanized, and more convenient communication functions can be added. Come on!
