Just an update... Thought I will try install Yosemite to see if the WWAN Module works in in version 10.10.5, and surely it did. The WWAN module without any kext installation showed up in my System Report under my USB devices as it was suppose to do, after the kext installation I was able to connect with my data sim card. So in short I doubt this will work in El Capitan even with updated kext, reason being it doesnt even reflect under my USB devices in System Report. Not sure if Apple "removed" it from 10.10.5 to 10.11 that it is disabled or so. Anyways if anyone has some info or input with regards to this it would be appreciated.
