Many people choose Apple phones because of their high power grid and stable system. However, Apple phones do not support dual card dual standby like counterfeit phones, nor do they support lighters, electronic scales and other functions. You can only choose to add a spare phone to equip the card, which is also very inconvenient to take out at ordinary times.

There was a loud bang of thunder, and the double sharing number came on the scene. Dual sharing account is a device that enables iPhone to realize dual card and dual standby function. It connects with iPhone through Bluetooth and sends the authentication message The information is sent back to the mobile phone and registered on the operator's network. When the connected mobile phone can use the data network or Wi Fi network, You can make and receive calls or send and receive SMS messages with dual phone numbers. You can use the second number without a standby phone Compact, more convenient to carry.

The color of the package is very young. The front side only shows that the color is simple, and the back side is marked with the details of the product. The inner lining is foam plastic to ensure that the product will not be squeezed. Let's have a pleasant 'unpacking'.

    Family photo: double number body, card taking pin, Micro SIM card cover, headset lanyard, instruction manual.

The product is white, with a Bluetooth button on the front and the function of indicator light. The size is about one yuan coin, and the size is 46.1mm * 25.7mm * 7.5mm

The lanyard provided is very convenient and can be easily hung on the mobile phone to prevent loss.

The lower end is the charging interface. The edge is very rounded and free of burrs.

The side opening can be easily opened with nails, but tools are still needed.

After opening, the interior is like this. You can see that it can be opened by gently pushing upwards, and then you can push upwards to lock the sim card.

After opening the card, put it into the card slot. During the pushing process, it was found that the card slot needs to be improved. The pushing is relatively dull, so it can be used after the back cover is closed.

When installing the card, I found that there were only four screws, so I couldn't help but disassemble them.

It looks like this after being disassembled. The structure is relatively compact, and the durability of the keys is fairly good.

After taking it out, we can see that on the left is the 55mA small battery, on the top is a HJ K24C256 EEPROM, on the right is the USB port fixed well, and on the bottom is the CSR1010 Bluetooth chip, which integrates a 16 bit processor, 64KB RAM, 64KB ROM, and also supports Bluetooth 4.1, and then PCB antenna.

Well, after looking inside, we will restore the product, install the card, hang the lanyard, and start testing the use of the dual sharing number.

To use the "dual account", first install the "dual account" APP software on the mobile phone. There are IOS and Android versions to choose from, which are described on the official website The feature of the 'dual sharing account' is that the weight of 6.3g can replace the spare phone, but the price is only one day's meal. However, I don't think that I can pay that much for 100+on the Internet. It takes about 15 days to charge for 30 minutes. I don't know whether the 55mA battery can last.

Then start to register. You can see that the dual account in the reminder only supports China Mobile/Unicom SIM cards. It must be noted here that if you use a local card, you may incur a domestic roaming fee, because according to official data, when a phone or SMS is accessed, it is transferred to the mobile APP by Suzhou Mobile operator or Qingdao Unicom operator.

Open the Bluetooth device on the mobile phone, keep the network smooth, click the Bluetooth device found on the mobile phone to complete the pairing.  

The main interface is simple and clear, including call message me, and you can turn off sound and vibration when selecting.

Use my mother's phone to dial the secondary card,~~~I was immediately surprised by the harsh bell (xia).

It is strongly recommended that the app provide a variety of ringing tones to choose from. Missed and closed calls will be displayed in the app.

Then let's try the dialing function. After clicking Dialing, it is similar to the phone with dual cards and dual standby, and the dialing selection appears.

After the actual test, the call quality is quite good.

But if you go beyond the Bluetooth range, dialing or texting will not succeed. Well, charge him and make a summary.

The emergence of dual sharing account undoubtedly facilitates many single card mobile phones like IPHONE, so that we can choose mobile phones in the future as long as we like, without worrying about whether our lucky cards are nowhere to be placed.

But at present, there are still some problems. The first is The dual account is transferred through the operator in Suzhou or Qingdao, Everyone knows that roaming charges are expensive, so this problem should be solved urgently. Secondly, the traffic of the secondary card cannot be used, resulting in waste. Finally, if the product wants to survive for a long time, it should add many auxiliary functions, such as Bluetooth loss prevention, and call vibration.
