🔗 Basic checks
Before anything else: run through this checklist
| Check | What to do |
|---|---|
| 📱 Phone compatibility | Depends on the model: Android 5.1+ / iOS 9.0+ for most ICE smart models, Android 6.0+ / iOS 9.0+ for ICE fit, Android 7.0+ / iOS 12.0+ for ICE smart junior, Android 8.0+ / iOS 10.0+ for ICE smart mimi, ICE smart SP 2.0, ICE smart forever and ICE smart band |
| 📲 App version | Make sure you have the latest version of your ICE app (ICE Smart, ICE fit, ICE JUNIOR or ICE BAND) |
| 🔵 Bluetooth | Turn Bluetooth off and back on on your phone |
| 🔋 Watch battery | Make sure the watch has enough charge (at least 20%) |
| 📡 Environment | Try pairing in an open space: walls, Wi-Fi routers and other Bluetooth devices can interfere |
🔄 Full reset procedure
How do I completely reset the Bluetooth connection?
- Open your ICE app (ICE Smart, ICE fit, ICE JUNIOR or ICE BAND) and remove the watch from the device list.
- On your phone, go to Bluetooth settings → find the watch in the paired devices list → tap "Forget this device".
- On the watch, go to Settings → Factory Reset and confirm.
- Once the watch has restarted, re-pair it through the ICE app (not from your phone's Bluetooth settings) by following the on-screen instructions.
- When your phone shows the Bluetooth pairing request, accept it.
💡 After the reset, keep the watch and phone within 30 cm of each other during pairing.
How do I check that the connection is complete?
Swipe down on the watch screen and check that the call icon and the connection icon are both green. If they are, the watch is properly connected.
👧 ICE smart junior: these watches have no call function. Just check that the connection icon is green.
💡 If one of the icons is not green, pairing is not complete: repeat the procedure and make sure you accept the Bluetooth pairing request.
