How to use it?
1. Purchase a 2g gsm SIM card, activate the SIM card through the mobile phone, and insert the SIM card into the kids phone smartwatch
2. You can set up dialling for 10 contacts and SOS calls
3. If you dont need the call function, you dont need to buy a SIM card, you can use all the functions of the Kids watch except for the call.
4. Music and video playback: use a micro-USB cable to connect to a PC computer (the watch does not recognize Mac computers), save music in MP3 format or video in AVI format in the SD card "My Music" or "Videos" folder (only supports original mp3 files and avi files)
