BG95-M3 problem with ppp0 interface

Dear Quectel,
I am using the BG95-M3 module with allwinner-a64 SOM using Ubuntu 18.04 OS. I’ve followed the instructions in the document “Quectel_LTE&5G_Linux_USB_Driver_User_Guide_V2.0.pdf” mentioned for USB serial option driver.

And I have followed the steps mentioned in the document to enable the ppp0 interface (Quectel_EC25&EC21_PPP_Application_Note_V1.0.pdf). Also, I’ve used the script to enable the ppp0 interface.

But I am still unable to connect to the Network, ppp0 is also not found in ifconfig. Please find the screenshot for reference.
