Throughout the game, you will receive various calls on the Holo Caster. However, if you missed vital information on them, you can access the Holo Caster in the item menu and play through all of the calls you have received on it. This is mostly just for nostalgia of your journey, and to make sure you're going to the right place if it has been a while since you played

Using the Nintendo 3DS's StreetPass features, you can pass various details to other players. When you do so, you will receive a StreetPass News announcement. This will give you details on how many people you have passed, how many PokéMiles you earned through it and a total amount of PokéMiles you have obtained throughout the game

Using the Internet, you have the ability to download special announcements for Pokémon X & Y. These announcements can be manually downloaded, or downloaded via SpotPass, the automatic download feature of the Nintendo 3DS. In addition to that, if you are nearby a special event, you can download special announcements and events there, through the Holo Caster. Many of these announcements are downloadable only for a limited time, due to the fact that the topic they pertain to is often time sensitive.

When you view these announcements, the game utilises the 3DS's cameras to create a 3D overlay, furthering the idea of it being a holographic broadcaster.
