NET light does not flicker after startup of SIM7600X, what should I do if the network is abnormal?
This situation may not be successfully connected to the network, you can follow the steps below:

Firstly, check the hardware connection, check whether the antenna is properly connected, and check whether the +SIM card can be used to make normal calls and surf the Internet in mobile phones and other devices: After checking the hardware connection, the software can use these instructions:

  • Check whether the SIM card is in good contact: AT+CPIN?
