SM-N900V Note 3 with Lollipop 5.0, rootable?, need tethering!

I just got this phone used and of course it has been updated. :eek:
So basically if it is anything like the rest of verizon's locked bootloader crap, unrootable. But I haven't followed this phone so I don't know if that is actually the case..

All I really want is unlimited tethering. :good:

Any advice and help is totally appreciated!
