since In 2007, Apple's first mobile phone came into the market. Until now, Apple has always supported a SIM card, which has caused great pain to our dual card family. Although there were products like Apple Peel later, they were heavy and power consuming, which would also affect the performance of the mobile phone, and we resolutely abandoned them... At the end of 2015, Hibiscus Life launched a very small single card mobile phone companion - dual sharing number! Let Apple, Samsung and other single card mobile phones achieve the dual card dual standby function.

Dual account supports China Mobile 2G,3G,4G Network and China Unicom 3G,4G Networked SIM Card, China Telecom will be supported later SIM Card; In order to facilitate different users, we have also prepared N ano-SIM Card transfer Micro-SIM Kakato connects the dual account with the mobile phone through the headphone lanyard. A good mobile phone friend, a lifetime

Family portraits:

It is small and exquisite, slightly larger than a dollar coin, but it has abundant energy and can work continuously after being fully charged fifteen God, a small head has great power!

The actual measured data are as follows:

It uses the latest Bluetooth 4.0 low-power chip - CSR 1010 module, which is small in size and fast in speed, Built in 50mAh lithium battery, The standard MicroUSB interface is used for charging, and the versatility is very good.

As can be seen from the figure above, if there is no baseband chip inside the dual share account, the dual share account is definitely unable to access the Internet. If you want to use the dual share account to access the network, you can give up

Software installation: scan the QR code or download it on the official website of CNL APP Yes, Apple and Android systems are available; After installation, you can see the status of dual account power:

After installation, the background application of the dual account cannot be closed. It is better to use the dial interface of the dual account (the interface can be read from the phone SIM Phonebook), the phone's own dialing interface cannot use the secondary card:

In order to test the actual call effect of the dual share account, the iOS 8.0 version iPhone 6 (all network telecom network) is specially used for call test under the wifi, telecom 4G, telecom 3G (no telecom 2G network...) network (the following test data is only for the local network state at that time, and the dual share account and the mobile phone are in a static state during the test):

IPhone 6 test results:

Wifi mode: clear voice call, slightly distorted voice;

telecom 4G: Voice call is clear and full, which is no different from direct phone call;

telecom 3G : The voice call is clear and full, which is no different from the direct phone call;

telecom 2G : Not found 2G Network, unable to test;

Meilan mobile phone (Android five point one double 4G Mobile network): on wifi , moving 4G ， 3G,2G Test results:

As can be seen from the figure above, when moving 3G and 2G networks, the dual account client has a warning prompt: the network is unstable! Since it is a test, we should try it if it is unstable.

Wifi Mode: clear voice call, slightly distorted voice;

move 4G: Voice call is clear and full, which is no different from direct phone call;

move 3G : The voice call is clear, full, and occasionally intermittent;

move 2G : The voice is slightly distorted, and calls can be made, but there is discontinuity;

   I didn't think it was moving 2/3G The network can actually make calls (I remember that the requirements of dual account for network speed are 300Kbps ）, which is beyond my expectation!

In addition to voice calls, the dual sharing account can also send and receive SMS messages, which is not different from the mobile phone. It is better for receiving verification and the like:

In general, the static test results are satisfactory, and the mobile status may be relatively poor. For example, when driving or taking a train, the communication base station switches frequently, and the network speed will also decline. This is just a guess.

Later, we learned through inquiry that the "dual account" 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.

Therefore, we are reminded that:

The SIMs in the dual account are roaming through Shandong or Jiangsu, and the roaming fee will appear on the secondary card. You must choose the nationwide roaming free package!!!

deficiencies:

one ： SIM Android phones cannot pass the verification within the dual account;

two : Scan QR code to download APP The touch screen on the Android download page almost doesn't respond (use Xiaomi instead 4C The same is true);

     Who says Apple can't double stay? --- Use the double sharing account to imagine a double-sided life!
