eSIM Travel Tips for Ireland
Driving the Wild Atlantic Way
The Wild Atlantic Way stretches 2,500 kilometres along Ireland's west coast from Donegal to Cork. Coverage is solid in major towns along the route. Remote sections of Connemara, the Aran Islands, and parts of Donegal can be very patchy. Download offline maps for any sections away from major towns.
The Irish diaspora connection
Many Australians visit Ireland tracing family history or simply feeling a cultural connection. County record offices and genealogy centres are in most county towns. Having data running helps navigate to the right offices and access family history databases.
Irish weather and planning
Irish weather is famously unpredictable. Rain can arrive at any time, in any month. Having live weather apps on your HelloRoam eSIM helps you plan each day around the conditions, particularly for hiking on the Wicklow Way or driving Connemara's back roads.
Dublin as a UK connection
Many Australians combine Ireland with a UK trip. Dublin to London flights are short and frequent. Your HelloRoam Ireland eSIM covers Ireland. Buy a separate HelloRoam UK plan for your British portion.
Australia and Ireland relationship
Australia has one of the largest overseas Irish communities in the world. Ireland is generally very welcoming to Australian visitors. No visa is required for Australians. Check smartraveller.gov.au for any updates before travelling.
Mobile networks in Ireland: Eir, Vodafone IE, and Three
Ireland has three main carriers. Eir (the former state carrier) has the widest rural coverage and reaches many remote areas of the west coast that others miss. Vodafone Ireland and Three Ireland are strong in major cities and along main roads. All three offer 5G in Dublin and other main cities. Your HelloRoam eSIM connects to the strongest available signal.
