Why use a free eSIM in Ireland?

A travel eSIM gives you mobile data without removing your physical SIM card. In Ireland, that means you can open maps, messages, hotel details, tickets and travel apps without waiting for airport Wi-Fi or paying daily roaming fees.

Install your Ireland eSIM before departure so you can open maps, messages, transport apps, and hotel details as soon as you arrive.
