An Ireland eSIM from eSpeedz starts at $7.99 and gives you prepaid mobile data on local networks from Dublin out to the Wild Atlantic Way. Install it from the QR code we email you before your flight, and it switches on as soon as your phone connects in Ireland.
From a Dublin pub to the Cliffs of Moher and the Ring of Kerry, keep maps, messages and taxi apps working without a roaming bill waiting at home.
A lot of Ireland trips are ten days or more, and most of them involve a rental car. On a US carrier day pass you pay for every one of those days, and on many T-Mobile plans the included data slows down once you've used the high-speed allowance, which is not what you want on a single-track road in Kerry with the satnav thinking. A prepaid Ireland eSIM covers the whole trip for one price.
Two things make Ireland a little different. First, coverage: Dublin, Cork, Galway and the larger towns are well connected, but along the Wild Atlantic Way signal gets thin on remote stretches of Connemara, the Kerry peninsulas and the Donegal coast, so download offline maps before you set off each morning. Second, the border. Belfast, the Giant's Causeway and the rest of Northern Ireland are in the UK. Our Ireland plan is built for the Republic of Ireland, so if your loop crosses the border, our Europe eSIM, which covers both Ireland and the UK, is the safer pick.
In Dublin, taxis are booked through FreeNow, Bolt or Uber, and all three send a licensed taxi on the regulated meter. FreeNow also runs in Cork, Galway, Limerick, Waterford and Kerry. For buses and trains, the TFI Go app sells tickets on your phone. Hotel, B&B and pub wifi is easy to find, but it's no help on the road between them, and that's where you'll use your data most.

In Ireland, navigation is the big data user because so many trips are road trips. A week split between Dublin and a few day trips is comfortable on 5GB. A 10 to 14 day loop around the Wild Atlantic Way, with maps running every day, music streaming in the car and photos going up each evening, fits 10GB better. If you'll stream shows at night or tether a laptop, the 20GB plan is the biggest Ireland option, and like every Ireland plan it runs for 30 days.
May through September brings the longest days and the best odds of dry weather for driving the coast, with July and August the busiest months. April and October are quieter and just as green. Whatever month you pick, pack a rain jacket, because the weather in the west can change several times in an afternoon.
