Even then it's iffy. Many phones don't really shut down when they're shut down, and if you really want to be paranoid even with the radios turned off they might still be receiving or something and phone home when you turn the on again.
But, still, at this point we're mostly small fish.
As a general note, make sure you either don't take photos of faces, tattoos, or anything identifiable, or just don't take pictures at all and leave that to the journos.
Yes, it's really best just not to bring your phone at all but if you must, like for emergencies, or you need it beforehand and then for some reason have no place to stash it then a Faraday container can come in very handy. It's also not 100% fool proof but if used right will prevent any signals from outside reaching your phone or any signals from your phone going out (as mentioned, you can not trust airplane mode.) There are DIY guides online for making your own.
