1.1 Create the following files (Configuration for China Unicom)
- /etc/ppp/peers/quectel-pppd
# /etc/ppp/peers/quectel-pppd # Usage:root>pppd call quectel-pppd #Modem path, like /dev/ttyUSB3,/dev/ttyACM0, depend on your module, default path is /dev/ttyUSB3 /dev/ttyUSB2 115200 #Insert the username and password for authentication, default user and password are test user "test" password "test" # The chat script, customize your APN in this file connect 'chat -s -v -f /etc/ppp/peers/quectel-chat-connect' # The close script disconnect 'chat -s -v -f /etc/ppp/peers/quectel-chat-disconnect' # Hide password in debug messages hide-password # The phone is not required to authenticate noauth # Debug info from pppd debug # If you want to use the HSDPA link as your gateway defaultroute # pppd must not propose any IP address to the peer noipdefault # No ppp compression novj novjccomp noccp ipcp-accept-local ipcp-accept-remote local # For sanity, keep a lock on the serial line lock modem dump nodetach # Hardware flow control nocrtscts remotename 3gppp ipparam 3gppp ipcp-max-failure 30 # Ask the peer for up to 2 DNS server addresses usepeerdns

1.2 Start Dialing
sudo pppd call quectel-pppd1.3 Set up DNS
modify the following file to add the DNS configuration：
vi /etc/systemd/resolved.conf
Fill in the DNS output from pppd, for example 114.114.114.114:
[Resolve] DNS=114.114.114.114
Restart systemd-resolved service：
sudo systemctl daemon-reload sudo systemctl restart systemd-resolved.service
Stop other network ports if necessary:
sudo ifconfig eth0 down sudo ifconfig eth1 down
