No 1 S3 Smartwatch

The No 1 S3 is a generic smartwatch powered by a Mediatek 2502 processor. It includes a SIM card slot and can connect to GSM mobile networks (850/900/1800/1900MHz). It can also sync with Android and iOS phones via Bluetooth. So, that means it can function both as a standalone watch or as a companion. All the basic “smart” features are included such as remote notifications, remote calls, music controls, fitness tracking, and more. The S3 is supposedly made of premium materials compared to No 1’s other watches. But it’s always best to take these claims with a grain of salt when Chinese manufacturers are concerned.
