Don't worry if speaking on the phone is hard. Text relay lets you type and read conversation with a relay assistant.
Quick answer
Use a text relay app or dial the relay number, then type what you want to say while the assistant speaks to the other person.
More detail
Relay services help people with speech or hearing difficulties communicate by phone.
You need a compatible device or phone method supported by the relay provider.
Emergency relay routes exist; check current Ofcom guidance for 999 text options.
How text relay helps
Visit the relay service website for the current app or dialling instructions in the UK.
Register an account if the service requires it.
Start a call through the app or access number.
Type your side of the conversation; the relay assistant speaks it aloud.
Read the text of what the other person says in return.
Tell friends and family you may use relay so they recognise the service.
Common mistakes
- Expecting standard home phone keys alone to type without an app or device.
