Can Apple Watch insert a card?

You can't. AppleWatch is a smart watch owned by Apple. It uses artificial sapphire crystal screen and ForceTouch touch technology, and combines motion tracking and health-related functions, which can be integrated with iOS and other Apple products and services. The first AppleWatch was released in September of 20 14. It supports dozens of functions, such as telephone calls, voice messages, connecting cars, weather and flight information, map navigation, playing music, measuring heartbeat and counting steps. It is an omni-directional health and movement tracking device. AppleWatch cannot insert the calling card. AppleWatch itself does not support card insertion, and there is no SIM card slot and SD card slot in the watch. After Apple Watch is connected to the cellular network, it can make phone calls, reply messages, receive notifications and other functions. On the iPhone, open the WatchApp and search for "cellular network" on the "My Watch" page. Click "Set up cellular network", and then follow the instructions for the operator to make a call.
