Will the eSIM work over the Sally Gap and Wicklow Mountains?

Not reliably. The Military Road across the Sally Gap and Wicklow Gap has long dead stretches through open moorland. Save your route offline before you leave the towns, and don't count on data at the high viewpoints.

Can I use it on the DART to Bray and Greystones?

Yes. The coastal DART line and both towns have strong coverage, including most of the scenic Bray-to-Greystones cliff walk, so you can navigate, share photos and check train times throughout.

County Wicklow eSIM: your local data guide.

Known as the Garden of Ireland, County Wicklow lies just south of Dublin, drawing walkers to Glendalough's monastic lakes, drivers over the moody Sally Gap and film fans to Powerscourt's waterfall and gardens. A County Wicklow eSIM keeps Wicklow Way trail maps, Glendalough car-park info and Dublin train times live as the mountains swallow the signal.

One eSIM for County Wicklow and all of Ireland. It's the national Ireland eSIM — from $2.15/day with unlimited data, working the same in County Wicklow as it does the moment you leave it.
