Use real-time text (RTT) with calls

Real-time text (RTT) lets you use text to communicate during a phone call. RTT works with TTY and doesn't require any additional accessories.

Note: The information in this article might not apply to all devices. To find out if you can use RTT with your device and service plan, check with your carrier. RTT uses call minutes, just like a voice call. 

Step 1: Turn on RTT

To turn on RTT, go to your Phone app settings

Step 2: Make a call with RTT

  1. Open your device's Phone app phone.
  2. Pick who to call:
    • To enter a number, tap Dialpad Keypad.

  • You can use RTT to call emergency services.
  • RTT calls include an audio stream. To mute or un-mute your microphone, tap Mute Mute.
