    Device cannot send data.

    (1) Check whether the SIM card installed in the device is installed in place. The SIM card must be a mobile phone card of China Mobile or China Unicom.

    (2) Check whether the SIM card is in a shutdown state.

    (3) Use the test key “TEST” manually to observe the “SIG1” signal light status, whether to access the mobile network, and observe the current environmental signal with mobile phones.

    Generally, it is a connection cable. The chance of software problems is not high. Check if it is loose.
