The 112 SMS service lets deaf, hard of hearing and speech-impaired people in the Republic of Ireland send an SMS text message* to the Emergency Call Answering Service (ECAS) where it will be passed to An Garda Síochána, the Ambulance service, the Fire service, or the Irish Coastguard. The ECAS operator will act as a relay between the texter and the required emergency service.
