Great question!
Smartphones, like the iPhone and many Android devices, have become so smart that they can now, after you've been using them for at least a few weeks, tell what you're going to use them for next, and have even been known to do these things before you attempt to, often without you taking any action towards this. They can also communicate with other smartphones, especially ones that you've communicated with a lot yourself. This technology is what allows modern smartphones to call other phones themselves.

Apart from the phone itself, it has to be within range of a working cell phone tower with capacity enough to take another call.
