China Unicom has officially launched its "eSIM No.1 Dual Terminal" service in six major cities: Shanghai, Tianjin, Guangzhou, Shenzhen, Zhengzhou, and Changsha. This groundbreaking feature allows wearable devices to share a user's mobile number without the need for a physical SIM card, offering greater flexibility and convenience.
The service is designed to be simple and user-friendly. Users can add an eSIM-enabled smart device, such as a smartwatch, and then link it to their main phone number. Once set up, both devices can receive calls and messages simultaneously, and users can make or answer calls from either device. This means you no longer have to carry your phone everywhere—you can stay connected even when you're out for a run or on a trip.
In layman’s terms, if your main phone rings, both your phone and your smartwatch will vibrate at the same time. You can pick up the call from either device, making communication seamless and uninterrupted. This innovation breaks the traditional reliance on a single mobile device for communication, addressing the growing demand for constant and flexible connectivity across multiple scenarios—whether for work, travel, or daily life.
Currently, the first supported device is the Apple Watch 3 with eSIM capability. Owners of this watch can access cellular networks directly through their iPhone, enabling them to make calls, send messages, and even use data independently. This means you don’t have to carry your phone with you when you go out or exercise, while still staying connected.
Additionally, the watch can sync data with your smartphone in real time, ensuring that all your health metrics, notifications, and other information are always up to date.
Residents of the six cities where the service is available can now visit a China Unicom business hall to sign up and experience this new level of intelligent communication. What’s more, from now until December 31, 2018, users who activate the new eSIM service will enjoy a 12-month discount on the eSIM sub-card usage fee, making it an even more attractive option for early adopters.
This move by China Unicom marks a significant step forward in the evolution of mobile communication, bringing us closer to a future where connectivity is truly ubiquitous and effortless.
