DZ09 --How does a watch work as a phone? By inserting a unlocked GSM 2G network micro sim card into the watch after you open the back cover, remove the battery and you will find the sim card slot, usually we suggest customers buy unlocked T-mobile micro sim cards as some carriers are not compatible with this watch, please make sure your micro sim card match these bands: GSM 850 / 900 / 1800 / 1900 MHz,Use your watch to make phone calls, send and receive SMS then. Notice:1.for iPhone series, not it just support answer & call, phone book, music play, camera, clock, pedometer, phone anti-lost alert. Still not support SMS, Radio, remote camera control, sleep monitoring, etc. Android mobile scan QR code on watch menu or the following link download app. 2.The watch is 2g network,it's slow for access the Internet.the RAM memory of watch is small,so the watch can't log in facebook,whatsapp and browser.but you can set message reminder in app,and you also can check message.
