      FAQ for Smart Watch Phone

      QWhy my new device cannot boot or start up properly?

      Please charge your new device for at least 10 minutes or more before first usage; this ensures normal device boot and optimal operation. For devices with removable batteries, ensure they are properly installed before charging.

      QWhy is there no response when pressing power button, home button and/or inserting the SIM card?

      Because when you press the two buttons simultaneously, the machine enters the “restore to factory default settings” interface. In order to quit this interface the device should be shutdown by long pressing power button and then you need to reboot it.

      QWhy the watch cannot connect to my cellphone?

      Please make sure whether the version of the Bluetooth and the OS of your cellphone all meet the requirements demanded by the watch. After you have ensured the compatibility, we advise to clear the record of connections and try to connect again.

      QHow to download the APP to connect the smartwatch to my cellphone?

      1. Scan the QR code (you can find the QR code on the instruction manual or on the desktop of the watch itself); 2. According to the OS of your mobile phone, you can download it from Google Play Store or APP store.

      QWhat is the difference between inserting the SIM card and not?

      If you insert the SIM card you can independently use most of its functions without connecting to your cellphone. While if you do not insert the SIM card, some functions will not work.

      QCan I download other themes or interfaces to my watch?

      It only supports built-in themes and interfaces and you cannot download others.

      • K8 3G del teléfono SmartWatch

        From Isabel Nov 29,2016

        Es un modelo de reloj muy bonito y elegante. Viene en una caja muy bonita, ideal para presentarla si vas a regalarlo.

        La bateria dura muy poco, si le das mucho uso, no dura un día completo. Tampoco enlazado por bluetoth se ven los watsapp completos, sólo el primero.
