Official Da Fit calling guide
Da Fit Bluetooth calling not working?
When a compatible Da Fit smartwatch syncs data but cannot make or receive calls, check whether Bluetooth calling is supported, then restore the phone’s separate Bluetooth audio connection and call permissions.

Understand the connection
Data sync and call audio can be separate.
Da Fit connection
The Da Fit app connection handles device setup, sync, settings, and many notifications. A working app connection does not by itself prove that phone-call audio is ready.
Bluetooth calling connection
On supported models, the phone may also create a Bluetooth audio connection for calls. This connection can be removed, disabled, or denied separately in the phone Bluetooth settings.
Step-by-step
Restore calling in the right order.
1. Confirm that the model supports Bluetooth calling
Open the model’s official product page or user manual. If Bluetooth calling is not listed, the watch may still sync in Da Fit but cannot be used as a call-audio device.
2. Confirm the Da Fit watch connection
Open Da Fit and confirm the Device page shows the watch as connected. If not, follow the official connection guide before continuing.
3. Check the phone Bluetooth audio connection
Open the phone Bluetooth settings and select the watch. If the phone offers call or audio options, allow them for the supported watch. If the connection is stale, remove it and reconnect the watch from inside Da Fit.
4. Accept phone permission prompts
Accept Bluetooth, phone, contacts, or call prompts only when the phone asks during setup. The exact wording varies by Android version and iPhone settings.
5. Test one incoming call
With the phone unlocked and the watch nearby, place a test call to the phone. Confirm whether the phone shows the watch as a call-audio option and whether the watch receives the call alert.
If it still fails
Separate a call problem from a notification problem.
Calls do not ring on the watch
Confirm that phone call alerts are enabled in Da Fit and that the phone can create an incoming-call notification. Use the notification troubleshooting guide if messages and calls are both missing.
Calls disconnect after the phone screen locks
On Android, background battery controls can interrupt Da Fit and Bluetooth behavior. Follow the Android background permission guide, then reconnect and retest.
