AT&T Real-Time Text (RTT)

Have a hearing or speech disability and want another way to communicate besides TTY? Get it with our free app or as a built-in feature of select smartphones.


About AT&T Real-Time Text

If you have a hearing or speech disability and want an alternative to TTY for communicating using wireless devices, you can use RTT1 , which uses a mix of text and voice. As a sender types a message on their device, text displays on the receiving device. RTT is great for everyday communication and is compatible with emergency calls, in the same way TTY is today.2

Want to communicate with someone with RTT or a TTY device? AT&T Real-Time Text uses our cellular network or Wi-Fi Calling to connect with users on networks that support this type of communication. As more carriers support RTT, you’ll be able to communicate with more users this way.

The AT&T Real-Time Text app is available through the Google PlayTM Store and Apple® App Store3 for no charge. RTT is also built in to select smartphones listed at

Important info about AT&T Real-Time Text

  • RTT to TTY and TTY to RTT communications may be limited by TTY capabilities. The conversation between RTT and TTY users requires one-way communication until the person finishes talking. Then the other person can respond with text. Text messages can only use characters that work with TTY. 
  • You may have issues when receiving calls on your RTT device if other softphone applications (for example, FaceTime® and Skype®) are running at the same time.
  • The app performs best on 4G-enabled devices. 3G network functionality is limited. 
  • Using the RTT service on a device other than an AT&T-certified device or on a network other than ours (for example, on Wi-Fi®) may affect the quality of the service.
  • Devices associated with suspended accounts operate in the same way as deactivated devices. Those devices can only make voice 911 calls and won’t be able to make RTT calls until the account is reactivated.
  • Our new 2-step sign-in process helps keep your info safe. Find out how to set it up
