Text relay services enable people with a hearing or speech disability to make and receive telephone calls via text with the assistance of a relay operator. In such a call, the relay operator communicates with the person who has a hearing or speech disability via text and with the other party via voice.

In Ireland the service is known as the Irish Text Relay Service (ITRS). To start an ITRS call to someone, first call 1800 207 800 and make sure that you have the phone number of the person you wish to speak to ready to give to the ITRS agent.
