- SIM card not recognized: Verify the SIM card is a Nano-SIM and inserted correctly. Ensure the SIM card is activated by your mobile carrier. Try restarting the watch.
- GPS inaccuracy: GPS accuracy can be affected by environmental factors (e.g., indoors, dense urban areas). Ensure the watch has a clear view of the sky for optimal GPS performance. LBS and Wi-Fi positioning provide supplementary location data.
