This specific plan is valid only within the Republic of Ireland (or, if it's a regional plan, you'd say "Yes"). This is the most important question. If you drive from Dublin to Belfast (Northern Ireland), your connection will stop at the border as it is part of the UK (non-EU). For a seamless all-island trip, we highly recommend our Europe Regional eSIM (which must include the UK).
HELP CENTER
Does this eSIM also work in Northern Ireland (Belfast, Giant's Causeway), or just the Republic of Ireland?
