Share This:

Real-time Text (RTT) enables users of the Apple iPhone to communicate in text via a phone call, eliminating the need for voice communication. This feature is especially useful for those with hearing or speech impairments. RTT allows text to be sent immediately as it is created, making conversations more efficient and convenient.

When RTT is enabled on both devices, no audio is heard on the call. To enable RTT on an iPhone, open Settings, scroll down and tap Accessibility, then scroll down and tap RTT/TTY. Tap the Software RTT/TTY toggle to enable it and you’re good to go!

RTT offers users several advantages over traditional texting methods. For starters, it eliminates the need for a “send” key as there generally is for SMS or chat. This makes conversations more fluid and natural as there are no delays between messages being sent or received. Additionally, since RTT works over IP-based technology on networks that support it, messages are delivered faster than traditional texting methods.

Perhaps one of the most useful benefits of using Real-Time Text (RTT) on an iPhone is that it allows people with hearing or speech impairments to communicate easily during phone calls with anyone else who has an iPhone with this feature enabled. By eliminating background noise from other callers, RTT allows these individuals to converse naturally without worrying about having their messages misinterpreted or misunderstood due to background noise interference.

Overall, Real-Time Text (RTT) for the Apple iPhone is a great feature for those who require a more efficient way of communicating via text during phone calls. Not only does it eliminate the need for a “send” key as there generally is for SMS or chat but also helps those with hearing or speech impairments by reducing background noise interference so they can communicate clearly and effectively with others on their iPhones who have this feature enabled too.
