Why does Apple add cellular networks to Apple Watch 3? The biggest reason is naturally based on the strong needs of users, the previous generation of Apple Watch 2 can only be connected through Bluetooth and wireless networks, so the watch can not be used off the phone, but also in the use of the scene is more limited, and the cellular network to join Apple Watch 3 is more richer in the application scene, such as: in the pool to take a phone call; in the running online songs; or through Siri send a text message, use it again from the shackles of mobile phones can be completely independent use, which also allows a lot of people Re-ignited the desire to buy Apple Watch 3.

Watch the phone may not be anything new, we are familiar with the children's watches have long been to support two-way call, but with children's watches generally use the traditional card-type design, so children's watches are generally more heavy, which for the pursuit of the ultimate size Apple Watch is clearly unacceptable, so AppleWatchSeries3 used in the embedded SIM card chip technology (ie eSIM card), which is a welding hardware in the device on the virtual SIM card, do not need to set up an independent card slot, Series3 only than the previous generation watch to increase the thickness of 0.2 mm to be able to achieve communication function.

Of course, the use of eSIM card is not Apple Watch 3's first, the domestic smart watch TicWatch earlier than Apple launched a separate call TicWatch 2, but the two in some respects there are still some differences. Specifically, TicWatch can only support 3G networks, and to watch the main terminal for the new number of applications; and Apple Watch 3 not only to support 4G network-based, and also supports mobile phones and watches the same number of sharing, which for The user is naturally more convenient, but to achieve more than one terminal also need to support the carrier to achieve.

According to Apple's official statement, Apple Watch 3 in mainland China will cooperate with the three major operators to launch the national version, but to participate in the world's first only China Unicom version, and also limited to belong to Shanghai, Guangdong, Henan, Hubei , Hunan and Tianjin Unicom mobile phone account, which also allows 4G users base huge China Mobile and China Telecom users are very disappointed.

So what is Apple Watch 3 that supports the cellular network to improve the user experience? First of all, of course, is a separate call function, you can "lose" the phone to achieve the perfect wrist call, while Apple Watch music, maps,stock, Weather and other functions are available through the cellular network real-time access, in the absence of WiFi outdoor scene advantage will be more prominent, especially in outdoor exercise, Apple Watch 3 can be a perfect alternative to mobile phones, so you can light into battle.

In addition, the use of eSIM card design Apple Watch 3 also allows users to more flexible choice of carrier packages, you can always replace the operator, no longer subject to restrictions on the network system, do not worry about card core damage and other issues, for the user Really brought real convenience. Not enough recent Unicom suddenly suspended the "number one multi-terminal" certification application, Unicom official reply is: "eSIM card test period is over, there will be a second test, time unknown, will be formally pushed through market".

to sum up:

Based on e-SIM card air write number, more space-saving advantages, has become the pursuit of small size of the inevitable choice of intelligent hardware, in addition, e-SIM card in the Internet of things, car networking field has a broad application scene. However, from the practical level, e-SIM card technology continues to need the support of operators to achieve, and Apple Watch 3 is also promoting e-SIM card in the smart wear equipment applications.
