Troubleshooting Methods for 4G Device Connection Failure

• 1. Press and hold the Reset button for 6 seconds to reset the device. After resetting, try adding the connection again.
• 2. Check if the device has sufficient battery power. Ensure that it is fully charged.
• 3. If the red light is flashing slowly, the signal is too weak. Please move the device to an area with a better signal.
• 4. If the red and blue lights are flashing alternately and slowly, the device has not detected a SIM card. Please insert a SIM card.
• 5. If the red and blue lights are flashing alternately and quickly, the data plan has expired, or the account has been suspended due to non-payment. Please recharge or replace the SIM card.
