How does Find My iPhone app work?
As the subject title suggests, my question is simple - How exactly does the Find My iPhone app work? Could someone try to shed some light on this for me please?
I assume it has something to do with a combination of the GPS technology and SIM card. And the phone requires power?
To put my query into context, I am undertaking a PhD studying the movements of seals. I was hoping to build into my tags some sort of technology similar to this, so that when the tag pops-off the individual and floats to the surface, I will be able to locate it similar to how one would find their iPhone.
Look forward to hearing how it all works...
