@danilo-burdese hi plz use below method for making a PPP internet purpose.

step1: opkg update
opkg install chat comgt

Step2: vi /etc/config/network

config interface 'hologram'
option defaultroute 1
option device /dev/ttyS1
option apn jionet //jionet place use your network apn
option service umts
option proto 3g
option 'pppd_options' 'noipdefault'

Step3: vi /etc/config/firewall
this you have to copy config forwarding above line.
config zone
option name 'cellular'
option output 'ACCEPT'
option forward 'REJECT'
option masq '1'
option mtu_fix '1'
option network 'hologram'
option input 'ACCEPT'
Step4: /etc/init.d/firewall restart
Step5: /etc/init.d/network restart

that's it thank you.

Hi @Nagarjuna-Reddy
does this works with any SIMCOM module? I am trying to interface A7672 with Omega.
This PPP link works on USB or UART?
It would be great if you could write bit around the hardware.

Thanks in advance.
