airdatalink does not currently provide an Ireland eSIM with a phone number or SMS capability. Only data‑only eSIM plans are available from this provider for Ireland, so travelers will not receive an outbound or inbound voice or SMS service.
Travelers who need to communicate while in Ireland can use popular VoIP applications such as WhatsApp, Telegram or iMessage over the data connection. However, some destinations may block or restrict access to certain VoIP services, so it is advisable to verify that the apps you rely on are reachable in Ireland before purchasing a plan.
