How to Turn Off RTT on iPhone

Real-Time Text (RTT) is a feature on iPhones that can be useful for certain users, but not everyone needs it. If you’re wondering how to turn off RTT on your iPhone, this blog post will guide you through the process.

What Is RTT on iPhones?

When discussing how to turn off RTT on an iPhone, it’s crucial first to understand what RTT is. RTT stands for Real-Time Text, and it’s a feature available on iPhones that significantly aids communication, especially for those with hearing or speech impairments. This feature allows users to send text in real-time during a voice call. As you type, the text appears instantly on the receiver’s screen, without needing to press send. This immediate transmission of text makes conversations flow more naturally and is especially useful in situations where audio communication might be challenging.

RTT works seamlessly over Wi-Fi or a cellular network and doesn’t require any special type of messaging plan. It’s integrated into the iPhone’s native calling app, meaning it’s readily accessible and easy to use for those who need it. The importance of RTT cannot be understated for the accessibility community, as it provides a vital communication tool.

However, for users who don’t require this functionality, the RTT feature might be unnecessary. In some cases, it might be enabled accidentally, leading to confusion during regular voice calls. This is why knowing how to turn off RTT on an iPhone becomes important. It’s all about tailoring your iPhone’s features to suit your individual needs and preferences, ensuring a more personalized and comfortable user experience.
