Control Photon via ios apps without connection?

Hello guys! I just got my hand on a photon for my camera slider project.
And while I’m playing with it, there’s a question that pop up in my mind.
So is it possible to connect to the photon via the ios apps even the photon are
not under any wifi connections?
For example, if I brought it with me in the wood for camping, is it still possible to connect
and control the photon via apps? ( I will have LTE signal on my phone, just not wifi )
Thanks guys, cheers

You could tether the Photon to your phone, or not?
