Real Time Text (RTT) – "Yes” means this device is capable of supporting RTT, but RTT functionality may depend on the individual device’s software as provided by the device’s manufacturer and the customer’s subscription. Please contact customer service for information specific to your device and plan.
RTT is a feature that provides voice call accessibility over Internet protocol (IP) enabled networks (i.e., Voice over LTE “VoLTE” or WiFi Calling) for people who are deaf, hard of hearing, deaf-blind, or have a speech disability.
Using an RTT-enabled mobile device, RTT allows text characters to be sent as they are created and/or be sent simultaneously with voice. It helps avoid the delay of typical text messaging while eliminating the need for specialized equipment.
RTT may be available to a GCI customer using a RTT-capable device on GCI’s network if (1) the customer has an active VoLTE subscription and RTT has been enabled on the device; and (2) the communication is being made using IP-based (i.e., VoLTE or WiFi Calling) technology only.
RTT functionality may depend on the individual device’s software as provided by the device’s manufacturer and the customer’s subscription. Please call customer service for information specific to your device and plan. RTT may support additional characters that are not available using TTY. In addition, RTT calls to 911 in Alaska may be answered by Public Safety Answering Points (“PSAPs”) using TTY.
