I have modified kext based on the cellphonehelper kext in macOS, I have posted it on my GitHub, maybe it can help you.

hello i have tested your kext the problem is that i cannot connect to the internet with the modem can you give me your base script.ccl? or you could paste your ppp log? i would apreciate it a lot, also if you can test from terminal "screen /dev/tty.wwan 115200" an ATD*99# command and what do you get? thanks
