There are 22 Personal Mysteries entries in the Notebook (which has a total of 83 items), but each one it’s usually comprised of 3-5 cell phones or even more, meaning there are in fact 87 Cellphone collectibles to be found in the game world.
Apart from the usual PP and Credits bonus, the Cellphones add to the story of Dead Rising 4, relating events that happened before or during the outbreak. Moreover, they count towards the “Can You Hear Me Now?” challenge, so you need all of them if you want a 100% completion.
You can always check your progress in the Notebook section of the Dossier, and the collectibles save as soon as you pick them up. They come as small cell phones, thus it’s not a bad idea to use the camera when you can’t spot them.
The Vendors in the Emergency Rooms sell maps which reveal their approximate locations, but they cost credits and you need to rescue civilians to upgrade the shelter to a higher tier before accessing certain maps.
That being said, our collectibles guide makes perfect sense because it saves you money and it also describes the precise locations of all Dead Rising 4 Cellphones. You can use the text which follows the same order as the maps, or if that’s not your thing you can watch our collectibles videos from YouTube.
