Hello, I'd like to use my old deactivated verizon Samsung Galaxy S4 phone as a VR (virtual reality) video streaming device that can be inserted into a goggle headset. For the streaming to work, I have to be tethered to my computer via USB so that the VR software can route the video stream to my phone.
The problem is, when I try to enable the USB data tether, my phone fails due to "checking subscription status".
I understand paying the extra for mobile hot spot, and mobile data tethering and all that jazz... but I did my time, paid for the phone and then some. And it's DEACTIVATED. Even on airplane mode, why can't I use USB tethering on my computer so I can enjoy full use of my old phone (except of course cellular calling)? 
Thanks
Chris
