Go to Roblox account Settings , open Account Info , then find Phone Number and tap Add Phone. Enter your number there, and Roblox will send a one-time code to that phone; type that code into the verification box to finish unlocking voice chat.

Where it’s entered

  • On web, desktop, or the mobile app , open Settings.
  • Choose Account Info.
  • Under Phone Number , select Add Phone.
  • Enter your phone number, then enter the code sent to your phone to verify it.

After verification

Once your phone number is verified, turn on Voice Chat in Privacy / Communication settings , then use the mic icon inside a supported Roblox experience.

Quick note

Roblox says phone verification for voice chat is only available on eligible accounts, and voice chat access also depends on age-check or other eligibility requirements.
