The current Android has been constantly improving its configuration, but because the bottom layer is still Android, its fluency is still not as good as Apple's, but the only disadvantage of iPhone is that it does not have dual cards and dual standby. When everyone likes to use several cards at the same time, and the Internet, life and work are separated, the phones without dual cards and dual standby can only go out with several phones, It is also easy to be stolen. At this time, the double sharing number artifact can perfectly solve this problem.

Appearance

The package of the double sharing number is unexpectedly simple. A yellow paper bag, like the old storage disk, is marked with the LOGO on the top.

On the back is the introduction of some double sharing numbers, as well as the introduction of the company. A large sticker was pasted on the packaging bag. Once it was torn open, the whole bag was rotten. You can't restore it. So if you want to give it away, don't itch to open it after buying it.

In addition to the package, there is also a more detailed introduction. Double cards, saving money, lightness, long standby, etc. are all features of the double sharing account.

Of course, there are many activities on Weibo and WeChat for Shuangxiang account. As a new product, it is also very conscientious to listen to the voice of users instead of thinking about making money first.

Open the paper bag. There are white thumb sized double sharing numbers. The accessories include SIM card sleeve, card pin and lanyard. Of course, the manual cannot be missing.

First, let's take a look at the main character, the double share number. He is white, fat and flat. He weighs only 6.3 grams and weighs as much as a one yuan coin. If he didn't get it, would he really not believe that such a small thing could be called and sent messages?

There is a charging port on the bottom of the dual sharing account, which is the same as the charging port of ordinary Android phones. It is said that the phone can stand by for 110 days after 30 minutes of charging, while it can be used for 15-20 days. There is no need to prepare another charging line, and there is no need to worry about running out of power during travel. It can use half a month after one charge. And because the power is not large, it can also be charged quickly. This is really good.

On the other side of the buttock, there are two mouths that look like being bitten by cockroaches. Don't ask me how I know why. This is actually used to hang the mobile phone rope. Because the double share account is a small one, you can choose to use the matching rope to plug it into the headset hole of the mobile phone, or you can buy the rope yourself. It is very convenient to hang it on the purse and backpack.

There is also a notch on the side, which is convenient for opening the double sharing number and inserting the card.

Use

In fact, the appearance is not very important, and easy to use is the king's way. How to play with this little thing? First, open the slot of the dual account, and you can see that it is like the card slot of the mobile phone.

Gently lift the iron plate of the card slot to put the SIM card in.

Put the SIM card in the card slot, cover it with the iron sheet, and then gently push the iron sheet forward to firmly fasten the SIM card. The card slot here is suitable for Micro SIM cards. If your card is a nano card, you can put on the matching card sleeve.

If you want to use the dual account, you still need to download an APP, not just a direct Bluetooth connection. Scan the QR code on the manual and download the corresponding version of the dual account APP.

The scanned download page also has an introduction to the dual sharing number. There are guides everywhere, so I'm afraid you won't use it.

To open the dual account APP, you need to register first. You can register with the number in your mobile phone, or you can register with the SIM card in the dual account. However, using the card in the dual account always seems to make mistakes, which is more convenient in your mobile phone.

After registration, you can pair the dual sharing account with Bluetooth. Remember to turn on the Bluetooth of your phone, press and hold the button of the dual sharing account, and the light will flash blue and red alternately. At this time, click on your phone to pair, which is very convenient.

The only physical key on the dual sharing number box will be on. The blue and red light in the pairing mode is very weak, and it will be hard to see in very light.

The red light is also very weak. Sometimes I don't know if the light is on without looking carefully.

Many people should be curious, what is the principle of such a small thing? Dual account sharing adopts the mechanism of separating SIM card authentication and communication. The hardware part is responsible for SIM card authentication and authentication, and the mobile phone APP is responsible for communication functions. The SIM card authentication information is read by the "Xinxin" chip, and transmitted to the mobile phone APP through Bluetooth. The APP is then transmitted to the operator's server through the mobile phone's IP channel, and the operator's return information is transmitted to the APP through the Internet, so as to achieve complete call and SMS functions.

The first time you make a call with the dual account number, a confirmation message will be sent to confirm the opening of the travel network phone.

In the dual account APP, you can not only view the phone's address book, but also see that there are friends who use the dual account in the address book, which is very smart.

When dialing, you can choose to use a mobile phone card or a dual number card. The dialling, address book, and call log interfaces are very detailed, just like the mobile phone.

Of course, in addition to making calls, the dual account can also send SMS messages without operator signals. As long as the mobile phone number in the dual account is in the WiFi environment, it can ensure that the mobile phone can make calls and send and receive SMS messages, without worrying about missing the phone calls of the boss and customers, or missing the takeout phone calls! However, the dual account does not support external SIM cards to access the Internet. If you like one card to access the Internet and one card to make calls, you can put the flow card in your mobile phone, so that you can kill two birds with one stone. The other thing is that the dual sharing account can select ringing tones and vibrations. However, the dual sharing account uses the media volume rather than the ringing volume of the phone itself, which should be noted.

Summary

The dual sharing account is really a very good product in terms of function. It allows you to carry one less mobile phone, and can achieve dual card and dual standby at any time. It is small and convenient to carry, only needs traffic, and the call quality is also quite good. However, due to the new product, there are still many shortcomings, such as unable to use traffic, the APP is easy to be closed by background cleaning, the interface is relatively simple, and so on. For users who need dual cards and dual stays, it is still a good choice, and we hope that the dual accounts will become more and more perfect!
