First-Time Use Precautions

1. It is suggested to connect an external power supply of 5V-12V when the module communicates using PH2.0 seat.

2. The module powers on upon electrification. After inserting the NB card for the first time, it is necessary to power it and wait 1-2 minutes for network registration.

3. Net—Network signal indicator light
   Blue light on for 0.06 seconds, off for 0.8 seconds: Not registered on the network
   Blue light on for 0.06 seconds, off for 3 seconds: Registered on the network
   Blue light on for 0.06 seconds, off for 0.3 seconds: Data transmission state (PPP dial-up state and when using internal TCP/FTP/HTTP data services)
   Extinguished: Shutdown or PSM sleep mode

4. To prevent damage to the internal flash of the SIM7070G module, use the "AT+CPOWD=1" command for safe shutdown instead of directly cutting off the power.
