You need a program to stream the content from PC to phone.
There are TrinusVr, VRidge and iVRy. Are all payware but have trial versions to try them. iVRy works the best.
With iVRy you need also to download and install on PC Steam and SteamVR (free)
The connection between PC and smartphone is made by a usb cable (USB 3.0 port on PC) and by enabling usb tethering on smartphone.
If you have a smartphone with screen about 5 - 6 inch and a resolution at least 1920*1080 it worth to try.
With smaller resolution e,g, 1280*720 don't worth.
You can fly native VR both X-Plane 11 and P3D 4.1 and of course play other games.
There is a topic at forums.x-plane.org about smartphone and native VR with suggestions and guides but I don't know if permitted to post the link.
