China Unicom announced that it has officially launched the “eSIM One Phone Number Dual Terminal (eSIM一号双终端)” (in Chinese) business in six Chinese cities including Shanghai, Tianjin, Guangzhou, Shenzhen, Zhengzhou and Changsha.
“eSIM One Phone Number Multi-Terminal (一号多终端)” means that one phone number can shared with the user’s smartphone and wearable devices, without the need for a physical SIM card. For example, using eSIM users can go out exercise without carrying an additional mobile phone; the data recorded by the watch can be synchronized to the phone in real time.
