Your QR code arrives by email within 5 minutes of purchase. Sorted before you fly from Dublin, Cork, or Shannon.
The HelloRoam app lets Irish travellers browse, buy, and manage e-sim plans for 175+ countries from their phone. Track data usage, reinstall profiles, and reach 24/7 support without leaving the app. Download it from the App Store or Google Play before your next holiday to Spain, Portugal, or the US.
eSIMs cut extra charges and skip the SIM card queue at the airport. With HelloRoam, you buy a plan online before you fly, scan the QR code, and you're connected the moment you land in Malaga, Faro, or New York. Your Irish number stays active on your physical SIM while the e-sim handles your data abroad.
eSIM requires an unlocked, compatible device, so phones older than 2018 generally do not work. Once installed, a HelloRoam eSIM profile locks to that device and cannot move to another phone. Data-only plans do not include a local number, so calls go through WhatsApp or FaceTime. Most Irish travellers find these trade-offs minor compared to savings of up to 77% versus Eir or Three Ireland roaming add-ons.
HelloRoam covers 175+ countries on 145+ networks, giving Irish travellers some of the broadest reach in the eSIM market. Plans start from a few euro per day with no contracts and no overage fees. Unlimited hotspot plans are available for remote workers who need data all day on a work trip or long holiday.
Getting an eSIM is worth it for most Irish travellers. A HelloRoam plan costs a fraction of what Eir or Three Ireland charge for a roaming add-on, and you can set it up before leaving home. As of April 2026, HelloRoam plans start at €1.37 per day. For a fortnight in Tenerife or a city break in Paris, the savings and ease far outweigh the 5-minute setup.
HelloRoam eSIM plans for the United States connect to premium partner networks in all major cities. Fixed plans start from 3GB for 12 days. Unlimited daily plans are also available. Irish visitors heading to New York, Boston, Chicago, or the West Coast get fast speeds without paying Eir or Three Ireland's international roaming rates.
HelloRoam's Europe regional eSIM covers 30-plus countries under one plan. It works in France, Germany, Spain, Italy, Portugal, and more, connecting to local networks including Vodafone Europe. Fixed data and unlimited daily options are both available. Irish travellers can activate the plan before departure from Dublin Airport and be online the moment they land at CDG or Barajas.
An eSIM for Europe is worth buying if you visit more than one country on your trip. A HelloRoam Europe e-sim covers 30-plus countries for one flat price, which beats buying a separate SIM card in Paris, Berlin, and Barcelona. France, Germany, Spain, and Portugal are all included. Set it up before you fly out of Dublin and you are sorted from the moment you land.
HelloRoam beats Airalo on several key points: a clear 180-day refund policy (Airalo offers none), access to 145+ partner networks including premium carriers, and 24/7 live chat support. HelloRoam covers 175+ countries with no activation fees and pricing that suits Irish travellers flying to Spain, Portugal, or the US.
