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.

Best time to visit Ireland from Australia
Ireland's summer from June to August offers the longest days and best chance of sunshine, though rain is always possible. The countryside is at its most vibrant green in spring from March to May. Autumn from September to October is quieter and has beautiful light. Winter is cold and wet but Dublin's pubs are warm and lively. St Patrick's Day on 17 March draws many Australians to Dublin, though accommodation books out quickly.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
