【Answer/Make Calls and Message Notifications】After connecting to Bluetooth, you can directly dial the phone number on the watch to answer the call, and you can synchronize the address book and call records. Thanks to the built-in microphone and speaker, you can answer/make/reject calls (and also play music) on the spot from your wrist, allowing you to exercise hands-free and smarter than any other watch in its class. Can receive SMS and APP messages (Note: cannot reply to messages).
