Link peripheral
First, connect 4G Module to board . You can check if the device is connected by the following command:
$ lsusb | grep -i Quectel Bus 001 Device 003: ID 2c7c:0125 Quectel Wireless Solutions Co., Ltd. EC25 LTE modem
The modem usually communicates with the host computer through a serial port. Check whether the system correctly enumerates the corresponding serial port devices:
$ ls /dev/ttyUSB* /dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2 /dev/ttyUSB3
Test the modem
First, open the serial port using picocom :
$ sudo picocom -b 115200 /dev/ttyUSB3
After the program starts, you can enter the following at command to check the status of the modem:
Terminal ready at+cpin? +CPIN: READY OK #Check whether the SIM card is in place at+csq +CSQ: 11,99 OK #Detection signal. 99 means no signal at+cops? +COPS: 0,0,"JIO 4G Jio",7 OK #View Carrier at+creg? +CREG: 0,1 OK #Get the registration status of the phone (0,1: indicates normal registration) at+qeng="servingcell" +QENG: "servingcell","NOCONN","LTE","FDD",405,854,49E31,91,2450,5,3,3,74,-124,-16,-91,-5,3 OK #Signal strength and quality of the currently connected service cell
If the modems return to normal, you can use the Ctrl+A Ctrl+X key combination to exit picocom .
Terminating... Thanks for using picocom $
Dial-up Internet via ppp
You can now try dialing using ppp :
$ sudo pppd call rasppp & #Background dialing
The complete dial-up process is shown as follows:

From the output of the program we can get the following information:
1.local IP address : 10.221.128.38 2.primary DNS server : 49.45.0.1
We can now configure the network based on the above information:
# configure the gateway $ sudo ip route add default via 10.221.128.38 # configure primary DNS $ echo "nameserver 49.45.0.1" | sudo tee -a /etc/resolv.conf
