Can a Huawei watch be inserted into a mobile phone sim card?

Some models of Huawei watches can accept mobile phone cards. For example, some models of Huawei Children's Watch, such as Huawei Children's Watch 3s, 3X, 3Pro, Super Edition, and Huawei Children's Watch 5XPro and 5X, support the installation of Nano-SIM cards, allowing users to make and receive calls directly. These watches need to use the standard Nano-SIM card of the three major operators in mainland China (China Mobile, China Unicom, China Telecom), and the SIM card needs to be activated for voice, SMS, caller ID services and data services. However, it should be noted that it is not All Huawei watches support SIM card insertion. For example, Huawei WATCH GT4 cannot insert a SIM card. In addition, some Huawei watches support eSIM technology, which means they can use electronic SIM cards without the need for a physical SIM card. When installing the Nano-SIM card, make sure the chip side of the card is facing up and is correctly inserted into the card slot. It is not recommended to use self-cropped Nano-SIM cards to avoid recognition issues. During the installation or card removal process, avoid using sharp objects to touch the metal pieces in the card slot to prevent damage to the watch.
