Foreword: iPhone is the best smartphone at present. I believe that no one can refute this statement, right? Only a single product can win the annual share of smart sales of mobile phones, I dare say there is only the iPhone! However, the seemingly impeccable iPhone has a fatal disadvantage, which is that it does not support dual card and dual stay. With the acceleration of the pace of life, everyone is likely to have more than one phone number due to work and social interaction. If you use an iPhone, you may buy an additional phone for the second phone number, This is why many iPhone users are still using another phone. In order to solve the problem of dual card dual standby for iPhone, many manufacturers have developed various hardware devices to try to solve the problem. However, these hardware devices are either designed strangely, or they must be equipped with a heavy mobile phone, so that they can use dual card dual standby, and they are extremely unstable. Recently, a device called "dual sharing number" was released. It is only the size of an eraser, but it can perfectly solve the pain point of the inability of dual cards and dual standby for the iPhone. So how about it? Let's take a look at the experience of Xiaobian!
The package of the Double Enjoyment Number is very simple, with only one bag. However, considering that this product has not been officially launched, the simple package is not enough. So let's skip unpacking and go straight to the point. The Double Enjoyment Number package includes a double Enjoyment Number device, a card taking pin, a card holder, a dust-proof plug lanyard, and a simple manual.
The appearance design of the dual sharing number is very common. The whole hardware body is made of PC material, and the color should be divided into black and white. There is only one button marked with the Bluetooth icon on the whole body, and this button is also the most important button in the whole pairing process.
According to the official website, the dual account is a device that supports charging. After charging, the power consumption is very small, and the battery life can be up to 12 days. However, according to my personal test, about a week's battery life is completely achievable, and charging is also very convenient. You can charge the dual account only by using a charger with a micro usb interface.
Considering that many users are NANO SIM cards, a micro sim card holder is included in the dual share account, and the whole sim card placement process is very simple. (By the way, the working principle of the dual account is also mentioned here: the "dual account" adopts the operation mechanism of separating SIM card authentication and communication. The hardware part of the dual account is mainly responsible for the authentication and authentication of the SIM card, while the mobile phone APP is mainly responsible for the communication function. The SIM card authentication information is read by the built-in chip of the dual account, and then transmitted to the mobile phone APP through Bluetooth, and then transmitted to the operator's server through the IP channel of the mobile phone by the APP, and finally transmitted back by the operator to the APP through the Internet, so as to achieve complete call and SMS functions.)
How can such a small device achieve such a large function? With curiosity, I opened the double sharing number, After disassembling it, I found that the internal structure of the dual sharing number is very simple. The motherboard chip occupies the entire internal space, while the small battery above is very interesting. It is such a small and precise component that constitutes such a powerful function.
The overall size of the dual sharing number is very small. It is especially small when placed with two No. 5 batteries. Because of the MINI design, I feel that this product has great market demand. Because it is small and convenient, it is the biggest advantage of this product.
The most favorite feature of the dual account is that the MINI body mentioned earlier, together with the complimentary lanyard, can be inserted into the phone as a dust-proof plug, which not only can easily bring the function of dual card and dual standby, but also can be used as a pendant.
The biggest advantage of the dual account is that it does not need to escape from prison. It only needs to download an APP to complete the function of dual card and dual standby. The APP download is also downloaded in Apple's official app store, and the registration can be completed soon according to the prompt. In addition, the dual account currently only supports China Unicom and China Mobile, and China Telecom will also be launched soon, which is a blessing for telecom users.
After the successful registration of information, all the operations of the dual account are carried out in the APP, including making calls, sending messages, and even receiving SMS messages. That is to say, a separate communication function is opened for you to use in the dual account APP without the built-in system communication function of the iPhone.
When you use the APP to make a call, you will be asked whether it is the SIM card in the mobile phone or the SIM card in the shared account. Here, if your mobile phone card does not activate the call display, then the shared account is an unknown call when it receives a call. Is there any way to optimize this function? Even if the caller ID is not activated, you can know who is calling, and the incoming calls are not marked with attribution, which makes it easy to receive fraud calls, The APP still needs to be optimized. In addition, there is no problem with the dual share account when answering someone's call, but when I dial someone, they can't hear my voice on the phone, and I can hear the other person's voice. This problem also needs to be solved. However, on the whole, the dual account APP is very convenient to use, but I hope to optimize it carefully before going public.
After connecting the Bluetooth box of the dual sharing account, you can see the current power in the APP. This function is well received, and the Do Not Disturb mode and the Jet Lag rest mode are also well received, but there is no operation to change the ring tone. I hope this can be added later. The last point is why the dual sharing account can not be used when there is no network connection? According to the design concept of dual sharing number, it should be possible to answer and make calls even if there is no network?
I thought the dual account was designed specifically for iPhone users, but according to the product introduction, this product also supports Android, but considering that most Android phones currently support dual card dual standby, then the dual account is nothing for Android users? The answer is no, you can use the dual account in this way. For example, a call card with an external dual account and a flow card with a built-in mobile phone constitute a dual card, dual standby and an additional flow card. However, the background erasure of Android is more frequent than that of iPhone, so how to ensure that the dual account runs in the background is a very difficult problem, This is a problem that needs to be solved for both Android and iPhone. In addition, the Android version of the dual account app is the same as that of the iPhone. When I test the call, I find that the other party can hear my voice, but I can't hear the other party's voice. When the other party calls, the call is normal again, and this happens again, Considering that this product has not been launched yet, some bugs are unavoidable at present, but these are small problems. The most important thing I think is that we need to solve the problem of not being erased by the background.
Finally, let me test a more interesting function, that is, put the dual account in bedroom 1, and then take the mobile phone connecting the dual account in different rooms, and then make a call to see if the dual account can push incoming calls. As a result, you can receive incoming calls from the dual account in every room! This also means that you can receive calls even if the dual account is not around you. (This test only represents personal opinions)
Experience summary: As a hardware device designed for dual card dual standby, I think the concept of dual sharing number is very good and successful, especially the body design of MINI, which is very pleasing. No one wants to install various plug-ins and wear various wonderful mobile phone cases for dual card dual standby. However, this product still needs to be optimized, For example, APP can do more. If it can support the use of dual account to access the Internet in the future, it will be even more powerful. It also needs to solve the problem of not being erased by the system background. In addition, it needs to further increase the call stability. In addition to these, dual account is a good product. At least this engineering version of my hand can experience the convenience brought by dual card and dual standby, It is not a natural product. In addition, this product will be launched in JD crowdfunding on December 28. Let's expect it to lead this kind of product with a strong price! Suggestions for product modification: 1. Add the attribution display. 2. You can't hear the other party's voice when you call. 3. Unable to make and answer calls without network.
