FAQ
No 4G Signal:
Ensure SIM supports 4G/LTE bands (B1/B2/B3/B4/B5/B7/B8/B28/B66) and has active data.
Verify APN settings match the carrier's 4G configuration (e.g., apn123456 [carrier APN]).
GPS Signal Loss Indoors:
Switch to LBS positioning (50-500m accuracy) or move to an open area for GPS.
Battery Drains Quickly:
Avoid continuous use of "Accurate Track Mode"; switch to "Intelligent Mode" for extended standby.
APP/Platform Offline:
Confirm 4G data is enabled and APN is correctly set; restart the device if needed.
Command Failure:
Ensure commands use correct format (e.g., centernum123456 [phone number]) and SIM has sufficient balance.
