Any good idea on how to run the script after Cellular connection established?
Maybe using hotplug script
/etc/hotplug.d/
You can refer to other script. For example
#!/bin/sh
. /lib/functions.sh
. /lib/functions/network.sh
[ "$ACTION" = "ifup" -a "$INTERFACE" = "wwan" ] && {
# do something
}
Thank you. That works.
