Real-Time Text

Real-Time Text (RTT) is text that is transmitted instantly when it is being typed or created. As quickly as characters are typed on the sending device, they are displayed on the receiving device. RTT is something that occurs swiftly!

Real-Time Text Benefits

Real-Time Text is especially helpful for people who are Deaf or Hard of Hearing or have a speech impairment. RTT is also useful for loud environments, or sending detailed information such as addresses.

Key Features of RTT:

  • Eliminates the need to connect to mobile TTY devices
  • Works on both the Cricket cellular network and Wi-Fi Calling
  • Offers a more natural conversation flow compared to TTY and relay services
  • Supports simultaneous text and speech on RTT-to-RTT calls

  1. Open the Phone app from your device.
  2. Tap More icon, then Settings.

Real-Time Text FAQs

RTT works as part of a phone's software so it doesn't require a separate keyboard device like a TTY. It allows much faster typing speeds and users can type messages and speak at the same time.
