Called by Cook is the ultimate Apple Watch that can completely replace the phone in a specific scene - Apple Watch Series 3 has been grandly launched.
The biggest upgrade of Apple Watch Series 3 is to support cellular networks. Apple has embedded an antenna in the panel of Apple Watch to make it have cellular network capabilities. As a result, Apple Watch has finally changed the previous generation Apple Watch can only connect with the iPhone to achieve some communication functions, completely get rid of the iPhone's shackles, allowing users to independently answer calls, send and receive text messages on the wrist at any time. Online listening to songs, navigation and other functions, users can simply run with their watches, climb mountains, swim, but do not miss any information, phone and WeChat, human-computer interaction will become more friendly and convenient.
The smart watch that can talk is not the first one of Apple Watch. Especially in China, it has become the basic standard function of children's smart watches. Therefore, some netizens joked that Apple Watch Series 3 should be a "watch that can make calls"---small genius A tribute to the watch. But from the perspective of technology implementation and user experience, the Apple Watch's support for cellular network functions is actually quite different from these children's smart watches.
There are two ways to add communication functions to smart watches. One is to set the card slot to insert the physical SIM card directly on the watch. Currently, the children's smart watches sold in China are all configured in this way, due to the SIM card and card slot. The need for device space has led to the widespread appearance of children's watches on the market.
The other is the embedded SIM card chip technology (ie eSIM card) used in the Apple Watch Series 3. This is a virtual SIM card soldered to the device hardware. It does not need to be provided with a separate card slot. The Apple Watch Series 3 is only a 0.2 mm thicker than the previous generation of watches.
Compared with the children's smart watch, the user needs to go to the operator's business hall to handle the physical SIM card access and registration. The data of the Apple Watch Series 3 using the eSIM card technology can be written to the terminal by means of over-the-air downloading, and the user is scheduled through a good program. Identity verification, online self-service account opening and activation activation.
In addition, eSIM card technology not only makes Apple Watch Series 3 free from the constraints of mobile phones to achieve independent cellular communication functions, but also further facilitates users to achieve the number one multi-terminal, that is, support Apple Watch and iPhone to share the same phone number.
Use the same phone number to share and synchronize data between Apple Watch and iPhone, ensuring that you can keep in touch with the outside world even if your iPhone is not around. I think this is the biggest selling point of Apple Watch Series 3, especially For those who use a fixed phone number for external contacts.
The Apple Watch Series 3 will be launched globally on September 22, and will be launched in cooperation with the three major operators in mainland China. However, Apple officially announced that it can participate in the world's first launch but only the China Unicom version, and is only limited to The China Unicom mobile phone accounts in Shanghai, Guangdong, Henan, Hubei, Hunan and Tianjin have greatly disappointed China Mobile and China Telecom users with a larger 4G subscriber base.
China's three major operators' 4G services have been in commercial use for nearly four years. In particular, China Mobile, which is the first of its kind, and China Telecom, which has recently completed 800MHz network re-farming, are far superior to the significant reduction in terms of network coverage and network performance indicators. China Unicom with 4G investment. So, Apple Watch Series 3 is the world premiere. Why does Apple only allow China Unicom to participate?
By analyzing the relevant information, the author believes that this may be related to China Unicom's active promotion of eSIM card technology and full cooperation with Apple's company, while China Mobile and China Telecom should be affected by the network support situation can not meet the relevant requirements.
