Real-Time Text (RTT) helps customers with disabilities communicate over the wireless network as an alternative to TTY. RTT uses a free-flowing mix of text and voice conversation, so as quickly as characters are typed on the sending device, they are displayed on the receiving device. Real Time Text is great for everyday communication and is compatible with emergency calls, just as TTY is today.
Real-Time Text lets customers with disabilities communicate using devices and services that work over the cellular network, and it works when using Wi-Fi Calling.
RTT compatibility depends on the device and the wireless network service provider.
