I believe everyone is familiar with the iPhone. Although the price is still difficult to be accepted by the public, it is undeniable that the appearance, technology and IOS system have always been the object of many manufacturers' imitation. The only dissatisfaction is that it only supports the use of a single card. In this age of information development, we believe that everyone has more than two phone cards, especially business friends who are accustomed to multiple phone cards. Faced with this problem, fans can only choose to carry multiple mobile phones, which not only occupies the pocket position, but also brings a lot of trouble to the call. When it comes to solutions, we have to think of adding other cards or disassembling them to add dual cards and dual standby, which not only brings trouble to missed calls, but also brings possible damage to the mobile phone. Of course, most of us are looking forward to a more convenient way for iPhone to support dual card and dual standby. Recently, a small box "dual sharing number" with only 6.3 grams was introduced into the eyes of Apple Fans.

It can solve the single card problem of the iPhone. I believe that fans prefer it. For the double card and double waiting in the current market, the most common thing is the embedding of the phone case. A slight phone case may make many people dislike it. After all, thin streaks are still popular. When it comes to small size, we have to say that the "dual sharing number" is a magic tool that makes the iPhone instantly become dual card and dual standby. Only a box the size of a thumb has brought us a lot of convenience. Just plug in the SIM card and use it immediately with Bluetooth connection, which can be said to be a very simple and practical magic tool. How about the actual experience? Can it really solve the big problem of iPhone? Let's get to know

For this dual card and dual standby device, we are more concerned about the stability and clarity of the call. After all, no one wants to get into trouble, and we prefer simple and stable operation. Back to the topic, let's see if this "Double Sharing Account" can really bring good news. It can be said that the outer packaging is very simple, as simple as only one small cloth bag for packaging. Personally, I think it is better to use a box for packaging. It seems that this kind of packaging is very cheap. The front side briefly introduces the highlights and parameters of the product, and the QR code provided can be scanned and downloaded directly.

In addition to the instruction manual and the small box with two shared numbers, the clip, lanyard and card sleeve are provided. The card sleeve is very considerate for iPhone users with small cards, so you can avoid having to find a card sleeve to use.

The double sharing number is really small in appearance design. It is only about the size of a thumb and very thin. After all, it is only 6.3 grams. It is made of frosted plastic, but it is still slightly rough. There is only one simple physical button on the front, which is mainly to turn on Bluetooth for connection.

As a Bluetooth dual card device, the chip "Singlecell" developed exclusively is used on the chip, but it can be so lightweight. It does provide us with convenience in carrying, but is it easy to lose if it is too small? I believe that the matching lanyard is also used to hang the iPhone and the dual account together. After all, the connection is based on Bluetooth, and the distance is still limited. The Micro USB interface provided at the bottom can charge the device. In terms of battery life, it only takes 30 minutes to charge, and it can last for 15 days. After all, it is Bluetooth connection, which consumes less power.

Another function worth mentioning is that when the mobile phone has no signal, as long as there is a WIFI network, it can also answer and receive information. This function can be said to be quite practical. After all, sometimes it will encounter some dead corners of network signals. In terms of disassembly and assembly, I feel it is a bit difficult, and I must use my fingers to slide and open it in the middle. The card slot provided is a Micro SIM card slot, which belongs to a medium card. Our current iPhones are basically nano SIM cards, and the matching card sleeve can also be used.

Next, we will introduce the part of the client. The dual sharing account is used with the client through Bluetooth connection to achieve dual card and dual standby calls. The client can be downloaded and used only through the outer package and instructions. At present, in addition to supporting iPhone, Android phones can also be used. Although Android phones currently have dual card and dual standby functions, If you are a friend of Doka, you can also increase the use.

The main interface of the client simply displays the three functions of call, message and personal center, and the registration can be completed by using the mobile phone number to register.

The binding process is very simple. Just long press the entity key of the small box, the light flashes, and the client will automatically be prompted to open a window. After opening the window, the binding process can be completed. The binding process is relatively simple and convenient. When we make a call, we will be prompted to dial out the dual card option. In the actual experience, the call is relatively clear, at least there is no noise of disconnection.

The interface is relatively complete. The address book, call log, dialing interface and information interface are almost the same as the call interface of our mobile phones. It is also easy to operate.

In general, the dual sharing account is really a very good dual card dual standby add-on device, which is good for iPhone users to solve the problem of single card. After all, the compact and thin design is good, but I personally think it is safer to hang on the phone. After all, it is very troublesome to lose it. The stability of the client and the clarity of the call are both good, and there are no missed calls when receiving other incoming calls. This is also important for us to achieve dual card and dual standby. If you are also interested in this, you may consider starting a solution to the problem of single card of iPhone.
