The trick comes down to the device you're using. To do mirroring with the GP1971F/1871F requires a device that can make it's own hotspot and this app (
iOS App Store link). For example, an iPad sold by any of the major mobile carriers with a 4g modem have this ability, some of the older wifi-only ipads or ipod touches cannot make a hotspot.
The recommendation is to pick up a device that can share it's internet, once you create the hotspot on the tablet or phone and connect the GP to that hotspot - the mirroring app on the device should work no problem.
Hope this clarifies, :sail
