Turn off RNDIS:
After installing the Cat.1 driver, if you do not use the development board network card to access the Internet, you must disable the RNDIS network card that comes with the development board to avoid data consumption.
You can send the following disconnect dial command to turn off the RNDIS function: AT+RNDISCALL=0
SIM usage:
The dual card slot of the development board is currently dual card single standby, and supports the SIM card software switching function. Only one data card is needed for daily communication, and the SIM0 card socket is used by default.
Before using the phone function, make sure that the SIM card has been activated for VoLTE
