Connectivity
Though the Xiaomi Watch S1 does not feature cellular connectivity (and therefore lacks 2G, 3G, or 4G compatibility), it makes up for this with a suite of other connectivity options. The watch supports Bluetooth 5.2 for efficient communication with multiple devices, NFC support for seamless transactions and data sharing, and a comprehensive suite of navigational technologies including GPS, GLONASS, GALILEO, BDS, and QZSS for accurate location tracking during outdoor activities. The watch also supports Wi-Fi 802.11 b/g/n, though this appears to be limited to the Chinese model.
