Have you ever heard of RTT on an iPhone and wondered what it is? Those who have difficulties hearing or speaking can communicate by using an RTT. But what exactly is it, and how can it be beneficial?

RTT is Real-time text, which provides speech and hearing impairments with a novel accessibility method. You can type and talk using RTT while the receiver reads the message immediately. Developed for those with hearing difficulties, hard-of-hearing people, and those with speech disabilities, but anyone who can hear can use it.

Real-Time Text technology makes it possible for people with speech or hearing disabilities to access text in real-time. Using RTT, you can use your keyboard while you speak while the receiver reads your message right away. 

All iPhone models six and above come with a version of RTT as standard. In some countries and regions, not all carriers support RTT, which means its availability is dependent on the carrier or network you use. 

However, if your service supports it, you can enable RTT via your phone’s Accessibility settings. You can enable RRT on your iPhone by following the given steps.

  • Go to Settings.
  • Click on the Search button or scroll down until you find Accessibility. If you find it, tap on it.
  • Among the options that you see, select RTT/TTY.
  • Now, you need to enable software RTT/TTY.
  • If you have a dual-sim iPhone, you must choose a line.
  • Then tap on Relay Number, and a window will pop up asking for the relay number you will be using to make service calls.
  • Enable the ability to answer all incoming calls as RTT. Confirm your decision once you have chosen an RTT answer instead of a voice call.
  • By selecting the Send toggle, you will be able to send characters as you type them.

Which iPhone Users Should Use RTT?

RTT is for people with hearing impairments, hard-of-hearing people, and people with speech issues. With the Phone app, you can access Software RTT built into your iPhone, which does not require any additional hardware. 

When you enable Software RTT/TTY on iOS, the iPhone will default to the RTT protocol when allowed by your carrier. So, if any user has an issue related to hearing or speech, they should use RTT.
