RTT and TTY: A Guide to Setting Up on iPhone in 2023

When you’re using your iPhone, you may notice the occasional “RTT” or “TTY” pop up on your screen. But what do these acronyms mean?

In short, RTT stands for Real-Time Text and TTY stands for Teletype. Both of these terms refer to the same thing: a text-based communication system that allows people who are deaf or hard of hearing to communicate with others in real-time.

RTT/TTY systems have been around for decades, but they’ve only recently become widely available on smartphones. On the iPhone, RTT/TTY is built into the Phone app and works with any phone number that supports the technology.

Real-time text (RTT) is a bidirectional accessibility feature for people who are deaf, hard of hearing or have speech impairments. It allows you to enter and display text during a phone call. RTT works with TTY and doesn’t require any additional accessories.

Teletype (TTY) is a technology used by people who are deaf, hard of hearing, or have speech impairments. When you make or receive a call using TTY mode, the other person will hear your voice as normal but will see your typed messages instead of your voice on their screen. You can use TTY with an accessory or without one. If you don’t have a TTY device, you can use RT

 

History of RTT and TTY

RTT has its origins in a protocol created in the early days of telecommunications to help people with hearing impairments communicate by telephone. TTY was developed in the 1960s, and both technologies have evolved over time.

In 2009, RTT was standardized as part of the third-generation Partnership Project (PPP), which is an international agreement between telecommunications service providers to improve mobile communications. Since then, RTT has been adopted by many countries and is now available on most major mobile networks.

If you’re using iPhone with iOS 11 or later, you can use RTT to place calls or send text messages to someone who also uses RTT-capable devices
