Connectivity Tips for Dublin
Dublin's weather changes fast, so live weather apps are especially useful. Temple Bar and the main tourist streets have excellent 4G, but pub interiors can reduce signal due to old stone walls. The Guinness Storehouse and Jameson Distillery both have outdoor 4G at their locations.
The National Museum of Ireland and Trinity College campus have functional 4G. Phoenix Park, one of Europe's largest city parks, has 4G at the main roads and visitor center but weaker signal deep in the park's wooded areas.
Download the Transport for Ireland app before you arrive for real-time DART and Luas updates, which need a live data connection.
Best Time to Visit Dublin
Dublin is a year-round city, but weather adds variety. June, July, and August are the warmest months, with temperatures reaching 18C to 22C. Long daylight hours, outdoor pubs, and coastal walks along the Howth Cliff Path and Bull Island are at their best. August's Puck Fair in Kerry draws visitors to one of Ireland's oldest festivals. St. Patrick's Day on March 17 is Dublin's biggest celebration, with parades, live music, and the city at its greenest. March weather is unpredictable, typically 8C to 12C, but the festive atmosphere is unmatched. September and October offer mild temperatures and the Wexford Opera Festival. The Bloom gardening festival in June at Phoenix Park is a local highlight. December brings Christmas markets along Grafton Street and festive lights. January and February are the quietest months, cool and damp, but pubs and live music venues provide warmth. Book accommodation at least two months ahead for St. Patrick's Day week.

Airport and Transit Connectivity
Dublin Airport (DUB) has 4G and 5G coverage across Terminal 1 and Terminal 2. Your HelloRoam eSIM connects to the network before you reach the arrivals gate. The Aircoach and Dublin Express bus services connect the airport to the city center in 30 to 45 minutes with outdoor 4G throughout.
The Dublin Bus 16 and Airlink 747 routes also run from the airport. The Luas Green Line runs from the suburbs to central Dublin and the DART connects the coastline. Dublin city center has no metro system, so buses and trams are the main public transport.
The Dublin Bikes app and various car rental apps all need live data.

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.
