preface

As an Apple fan, I have been using iPhone for nearly ten years. I can only envy others who use dual card and dual standby phones and enjoy the privileges of different operators, or the phone numbers that are clear between public and private. But now I don't have to envy them anymore, because I have a double number! It is a smart hardware produced by Beijing No. Life Network Technology Co., Ltd., which can enable your iPhone to achieve dual cards and dual standby.

1、 Appearance

The express package is a standard large envelope with almost no change in thickness. After being folded, there is only a small paper bag with promotional stickers 10 cm square.

        Inside the paper bag is an ultra-thin dual number, and it also includes a Micro sim card holder that can be inserted into the Nano sim card, a plug cord that can be inserted into the phone headset hole, a metal pin for card retrieval, and an extremely simple manual for printing.

        The appearance characteristics of the double sharing number can be described in three words: small, refined and light.

        Small : The appearance size is 46.1X25.7X7.5mm, the area is the size of two one yuan coins, and the thickness is less than 8mm Its size can be said to be surprisingly small to the extreme. Even so, I still hope to optimize the structure and make the bank card thinner and easier to carry.

        light : The weight is only 6.3g, which is lighter than the one dollar coin. It is super light.

        essence : The frosted matt surface is exquisite, very warm, and the seams and openings are also delicate, especially the design of the rope hook is exquisite, and the overall workmanship is fine.

Disadvantages: In consideration of weight reduction, the Sim card stainless steel compression plate inside is too thin, and it feels that it will be damaged and bent if you don't pay attention to it, so it should be thickened. In addition, the color of the white switch is different from that of the shell, which is not as comfortable as the color of the shell. If it is made transparent, it is also good, which is easier to observe the indicator light.

2、 Usage

The use of dual account is relatively simple. First Load the second Sim card into the shared account, and turn on the Bluetooth switch of both.

Then Scan the QR code to download the dual account app and register. There are three options on the main page: communication, message and me. You can perform communication dialing, SMS operations and view your personal home page information As well as the setting of dual sharing number.

Enter the address sub page to view the address book and Communication record and dialing operation.

The double sharing number has five characteristics: new, long, high, low and difficult.

        new : The function is novel, which solves the problem that Apple mobile phones cannot have dual cards and dual standby.

Long : The standby time has reached 15 days (the official promotion needs to be verified in the future), and the power display is available, so frequent charging is unnecessary.

High : Because the dual account is accessed through the server in Suzhou (mobile card), if the sim card of others and the dual account sim card are local cards in other regions, the use of the sim card when answering and making calls will result in additional call charges or roaming charges, which is high in domestic use. It is recommended that the sim card with dual account can use the national free answer and dial out charges.

Low : When you use it abroad, you can use the free Wifi network to answer and make domestic calls. The charge is based on the domestic calls of this card, and there will be no international roaming charges. The cost is quite low. When there is no Wifi network, you can also answer and make calls through the traffic of the mobile phone card, but the international roaming traffic is also very expensive. After consulting with the mobile phone, it costs 3M/3 yuan. The official said that the call duration of about 10 minutes a day will cost about 5M of traffic 。

        hard : The charging standard is not mentioned in the manual, and it can be obtained by contacting the official customer service (The 24-hour hotline in the instructions is also not worthy of the name, and only during working hours on weekdays can someone answer it.) It was only after several phone calls that we got a preliminary understanding. Self understanding is difficult! There should be a detailed description of the use of tariffs in the form of tables.

There is a bug that when you enter the SMS page of the home page, you can't send SMS messages to contacts with multiple numbers. When you stop on the selection page, you feel like the phone is dead. You can only force the app to close and re-enter. It is normal to send SMS messages through contacts in the address book.  

        3、 Summary

The dual sharing number is small in size, fine in workmanship, lightweight and portable, and has a long standby time. It has solved the problem of not being able to use dual cards and dual standby for fruit fans for a long time. What is particularly commendable is that you can use the free wifi network to make calls abroad, but still charge according to the domestic tariff, or use the flow of the sim card in the mobile phone to make calls, which is also very convenient.

Existing problems: First, service access is limited to Suzhou (China Mobile), and some phone cards will generate domestic roaming charges; Second Due to the new products, different customer service explanations about the charges are different, which makes us confused, When the mobile phone uses a foreign card, can the dual account be used and how can it be charged? Not yet known. In addition, since Bluetooth has been used to connect with mobile phones, some expansion functions such as loss prevention should be added,

Suggestion:

1. Increase the appearance of thinner card form;

      2、 Add anti loss and phone search functions;

      3、 Increase the number of access servers, at least one in Beijing Tianjin Hebei region;

4. It is suggested that we should hurry up to carry out use tests in different countries and regions, and make detailed instructions on use and charges for easy use.
