An Ireland eSIM is a virtual SIM card that connects you instantly to Irish mobile networks (Three Ireland, Vodafone Ireland, Eir) without a physical card. Plans start at ~$1.60 for 3 GB, up to $47 for unlimited.
Do you really need an eSIM? Ireland benefits from free EU roaming from France, but quotas are often limited (10-25 GB). For 2+ week stays or heavy data users, an eSIM is more economical.
