Dual-shared generation generation old users, because the Bluetooth connectivity of a generation of products is not very stable, the daily use is relatively unsatisfactory, attention to the current out of double enjoyment number Pro (actually is the second generation), the use of Wifi connection, based on the occasional travel abroad to use double Enjoying a special convenient experience, got a Pro to do Aunt Zhang's first test.
First, what is the double enjoyment number? What is the principle?
Second, what is the difference with generation?
Third, my main application scenario
Fourth, simply talk about the advantages
Fifth, focus on the shortcomings
Six, do you need it?
Borrowed to know the user @ Lin Xiaoyi's answer: The principle of the dual card is to read the second card's authentication information and send it to the mobile phone via Bluetooth, and then through the IP network (the first card's wireless network or wifi) The operator's gateway MSC and VLR/HLR de-authenticate that the short message and the telephone also connect to the operator's gateway MSC and the short message center through the IP network, so this device is different from the apple skin, does not need to have the base band module.
In simple terms: Place your mobile phone card remotely on dual-shared servers. Is the server located in Suzhou? (A bit forgotten, anyway), in Suzhou and China Unicom Network (mobile stopped, now only supports Unicom, is said to follow up) docking, mobile APP and dual-share device connection (Generation and Pro slightly different, capacity After the analysis), answer the phone and SMS via APP. After analysis of good and bad, simply understand it.
Second, what is the difference with generation?Because the generation has been measured on Aunt Zhang, so the introduction of a generation please search on their own, mainly to talk about the difference between Pro and a generation.
The way that a generation connects to a mobile phone is Bluetooth, which means that although you can implement dual SIM dual standby for the iPhone, you still have to bring a small Bluetooth device, and I lose this type of person, and then you need to charge the device. It can be used for a long time (20 days - 30 days), because I am an Apple family barrel, obsessive-compulsive disorder also put an Android line for it every time, boys' bags are already lack of space, heart tired.
The innovation of the Pro version is to abandon the connection of the Bluetooth module and adopt a pure network connection. You can put the Pro version at home and connect it to your home's Wifi and directly connect the SIM authentication information to the dual-shared number server.
Simply speaking, a generation: SIM authentication - Bluetooth to mobile phone - mobile network to dual share number server
Pro version: SIM authentication - stable Wifi network - dual share number server ↠mobile network read
Third, my main application scenario I did not have the need for dual card dual standby. I did not owe loans and did not owe money. I have been using a mobile phone to work and live all the time. But occasionally my brain fever will buy tail ticket and go abroad, but I need to make domestic calls (mostly express The call to Zhang Da Ma harmed me. At the same time, taking into account the needs of the Internet, it was simply a matter of price to call and access the Internet from outside China Unicom. Usually the local traffic card was purchased at the airport. Then the problem came, and I had to pick up the domestic call and go online. , Also want to save money, double enjoyment number is really just needed.
The domestic calling card 4G package has no roaming in the country and is placed in the double enjoyment number. Even if the authentication location is in Suzhou, there will not be roaming charges. The Unicom package will not be used for hundreds of minutes each month, so I have always had anywhere in foreign countries. After liaising with the family, the local traffic card guarantees that I can meet the demand for dual-share access to mobile phones and local Internet access, which is perfect.
Fourth, simply talk about the advantagesFirst of all, it solved the pain point that I didn't want to bring more equipment out. This product did not need to be recharged because it was directly connected to the 5V charging head. There was electricity in the house and I was relieved to use it.
The biggest highlights:
Compared with the generation, due to the use of different SIM authentication methods, if you use a generation, if the mobile phone Bluetooth is not connected to the device, the call is turned off, and the second generation is unanswered, and then when you open the app, Remind you that someone called you. When using a generation, Bluetooth is often not connected, resulting in the phone card is not actually in the network, missed calls will not prompt, Pro version due to authentication via Wifi stable connection to the server, in the APP automatically retains the records of missed calls Even though I did not open data traffic to receive the call at the time, at least I knew who had called me and had no side leakage.
Because it is a Wifi connection, the network is much more stable than the previous pure mobile phone traffic. Although the network traffic (or Wifi) is still required for the call, the actual effect is better under the same scenario. It may only be a psychological feeling.
The Pro version of the APP is different from the one in the previous generation. The call recording has been added, and the call quality detection (network detection) has been added. The incoming call and the SMS ring tone can also be set freely (it can be different from the system call tone). In the actual use, it is better to use the missed call alert in the communication section. See section 2 for details.
I combined with the millet smart socket, shut down at night, automatically boot in the morning, to avoid harassing the phone, the small partner called you up at night to pee, hehehehehehehe.
Pro version can not solve the needs of my overseas use, Pro version of the phone card on the home and Wifi connection is very convenient for daily use of dual-card dual standby users, such as when I occasionally buy a flow card, but overseas Using the domestic segment, whether it is from home to the airport, or from the airport home, the network vacuum has lost contact with the world.
The commemorative edition of the project was a good name, but gave me a PCB board, no shell, no shell, no shell, this is to force me to die this obsessive? In the evening, the indicator light is super bright, flashing titanium eye.
I really don't think there is a need for a Pro version to be an app. Although it's easy to use, I still have a generation and I need to have 2 apps in the background. Secondly, although the Wifi activation device can be switched during setup, it is actually not easy to use, and the Wifi environment of the replacement device is really laborious. Also, the newsletter section will show the same contact's phone and SMS mixed together, really! of! one! point! All! Do not! high! level! , And it's hard to use.
If you strongly need dual-card dual standby, and the mobile phone is not natively supported, the secondary number is not tied to any financial category, I think I can buy it.
If you go abroad to play, want to report to your family at any time safe, to answer all kinds of courier brother cordial greetings, I also think that you can buy.
