@Dark_Nate I suggest against it.
You can easily nitpick elements that are activated.
Can you tell me which ISP are you opting for?
And,It really depends on OS.
but you can exploit TR-069.I am not very sure because I never tried it but it should be a feasible way provided router is not provisioned like JIOFIBER.
Well,If you can try with connecting your phone to the ONT.If the device allows mtp,it must be known and usable OS underlying....
If someone can try....we would be one step closer....
I would have got the jiofiber for tinkering but it is not available in my area.
But the usb port,can also be used.
Just to clarify,JioFi2 works on Android.
But we have not yet been able to unlock it's bootloader.
But things can change anytime.
