How to Turn Off RTT on iPhone: A Step-by-Step Guide

Real-Time Text (RTT) is a feature available on iPhones that enables users to send text messages in real time during phone calls. While this feature can be useful for individuals with hearing or speech impairments, there may be situations where you prefer to disable RTT on your iPhone. In this comprehensive guide, Techbangalore will walk you through the step-by-step process of turning off RTT on your iPhone, ensuring that you can make informed decisions regarding your device’s settings and functionality.

What Is RTT/TTY on iPhones?

Before we delve into turning off RTT on your iPhone, let’s briefly discuss what RTT is and how it works. RTT allows users to exchange text messages while engaged in a phone call, allowing for instant communication without the need to wait for each letter to be typed and sent. This feature is particularly beneficial for individuals who rely on text-based communication methods.

Who Is RTT For?

RTT (Real-Time Text) on iPhone is primarily designed to benefit individuals with hearing or speech impairments. It provides a real-time text-based communication method during phone calls, allowing them to participate in conversations more effectively. Here are some groups of people who may find RTT useful:

  • Deaf or Hard of Hearing Individuals: RTT enables individuals who are deaf or hard of hearing to communicate using text during phone calls. It eliminates the need for relying solely on voice communication, allowing for better understanding and participation in conversations.
  • Speech-Impaired Individuals: For individuals who have difficulty speaking or are nonverbal, RTT offers a convenient alternative for expressing themselves during phone calls. They can type their messages in real-time, ensuring effective communication with the other person.
  • Individuals with Communication Disorders: People with certain communication disorders, such as aphasia or dysarthria, may struggle with verbal communication. RTT provides a text-based method that bypasses these challenges and enables clearer and more efficient interaction.
  • Individuals in Noisy Environments: RTT can be beneficial in noisy environments where it may be difficult to hear or understand the other person on a phone call. By relying on text-based communication, individuals can bypass the noise and ensure effective communication.
  • Language Barriers: RTT can also assist individuals who face language barriers during phone conversations. Text-based communication allows for clearer understanding and reduces misunderstandings that may occur due to language differences.
  • General Users: While RTT is primarily designed for individuals with specific needs, anyone can use it on their iPhone. Some users may simply prefer text-based communication during phone calls, find it more convenient, or have specific situations where RTT becomes useful.

To disable RTT on your iPhone, you’ll need to navigate to the Accessibility settings. Follow these steps to access the necessary settings:

  • Unlock your iPhone and go to the home screen.
  • Tap on the “Settings” app, which is represented by a gear icon.

Additional Options and Considerations

While disabling RTT on your iPhone, it’s worth exploring other related settings and considerations that may enhance your overall experience. Here are a few notable options:

  • TTY: TTY (Teletypewriter) is another text-based communication feature. If TTY is enabled, you can toggle it off in the same RTT/TTY settings menu to fully disable text communication during phone calls.
  • Hearing Aids: If you use a hearing aid device that supports Made for iPhone (MFi) functionality, you may find settings related to hearing aids within the Accessibility menu. Be sure to check if any adjustments or configurations are necessary to optimize your hearing aid experience.


In conclusion, knowing how to turn off RTT on your iPhone gives you control over your device’s communication settings. Whether you wish to disable RTT due to personal preference or specific requirements, following the step-by-step guide provided in this article will help you accomplish this task with ease. By accessing the Accessibility settings and disabling the RTT feature, you can tailor your iPhone’s functionality to suit your individual needs. Remember to explore other related settings, such as TTY and hearing aid configurations, to ensure a fully personalized experience with your iPhone.


Will turning off RTT affect my regular text messaging?

No, turning off RTT on your iPhone will not affect your regular text messaging. RTT is specifically for real-time text communication during phone calls and does not impact standard SMS or messaging applications.

Can I enable RTT again if I decide to use it in the future?

Yes, you can enable RTT again on your iPhone by following the same steps mentioned earlier and toggling the switch next to “RTT” to the on position in the RTT/TTY settings menu.

Will disabling RTT improve my battery life?

Disabling RTT is unlikely to have a significant impact on your iPhone’s battery life. RTT consumes a minimal amount of power, and turning it off is more about personal preference and specific communication needs rather than conserving battery.
