Learn about Real-Time Text (RTT)

You can use Real-Time Text (RTT) on your mobile device if you have a hearing or speech disability. RTT allows for character-by-character transmission of messages in an alternative text format.¹  As a sender types a message on their device, text (by letter or symbol) displays on the receiving device. RTT is great for everyday communication and is compatible with emergency calls.²

RTT uses our wireless network or Wi-Fi Calling to connect with users on networks that support this type of communication.
