Ensuring your Vault in Fallout Shelter thrives is a key aspect of the game. Maintaining a sufficient number of Dwellers is crucial for the functionality of your Vault, as they are needed to work in rooms and generate essential resources.

Unlocking various rooms and advancements often requires a specific number of Dwellers to be present in your Vault simultaneously. Therefore, early access to and effective use of the Radio Studio in Fallout Shelter can significantly benefit your Vault's growth.

Unlocking and Operating the Radio Studio

To acquire the Radio Studio, you must first maintain a population of 20 Vault Dwellers. Expedite this process by completing Quests for Lunchboxes, which may contain additional Dwellers, and by expanding and enhancing your Living Quarters to encourage Dweller procreation.

Once you meet the Dweller requirement, unlock the Radio Studio by investing 600 Caps to construct the initial room. Start operating the Radio Studio by assigning two Dwellers of your choice to the room. Opt for Dwellers with high Charisma, as this attribute is crucial for the Radio Studio's effectiveness.

By activating the Radio Studio, you broadcast signals to the Wasteland, attracting potential new Dwellers to your Vault. To manage population levels, toggle the broadcasting feature on and off by adjusting the 'Wasteland' switch within the room. Expanding the Radio Studio into double or triple rooms allows more Dwellers to work simultaneously, enhancing efficiency.
