Each plan connects to the strongest 4G and 5G networks in that city. Irish city break travellers get instant data activation with no SIM swap and no kiosk queue at arrivals.

London is the most-purchased city e-sim from Ireland, followed by Paris, Barcelona, New York, and Tokyo. HelloRoam London plans connect to EE, Vodafone UK, and O2. Paris plans link to Orange France and SFR. Barcelona plans connect to Movistar and Vodafone Spain. New York plans run on T-Mobile and AT&T.

HelloRoam city eSIM plans start from €0.89 per day as of April 2026. Fixed data options run 3GB to 20GB, valid for 12 to 30 days. Unlimited daily plans suit Irish travellers who stream, use maps constantly, or video call home throughout their city break. Compare that to Eir or Three Ireland non-EU roaming at up to €4.99 to €6.99 per day. A 7-day city break saves most Irish travellers 60 to 80% with a HelloRoam city plan.

HelloRoam eSIM Singapore plans connect to Singtel, StarHub, and M1. Singapore is a popular stopover and city break destination for Irish travellers heading to Southeast Asia, and it has one of the world's best mobile networks. Fixed data plans start from €0.89 per day. Unlimited daily plans are available for longer stays or remote work. No Eir or Three Ireland roaming add-on needed. Activate before you fly from Dublin and you are online from the moment you land at Changi.

HelloRoam eSIM London plans connect to EE, Vodafone UK, and O2 across the whole city. London is the most popular city break destination from Ireland, with direct flights from Dublin, Cork, and Shannon to Heathrow, Gatwick, and London City Airport. Fixed plans run 3GB to 20GB valid for up to 30 days. Unlimited daily plans are available too. No Eir roaming add-on needed. Activate the QR code at home the night before and you are online from the moment you clear arrivals.

HelloRoam eSIM Paris plans connect to Orange France and SFR. Paris is one of the most popular short breaks from Dublin Airport, with direct flights making it one of the quickest European city breaks from Ireland. Activate the HelloRoam city e-sim before you board and you are online from the moment you clear Charles de Gaulle or Orly. Fixed data plans start from €0.89 per day with no Eir or Vodafone IE roaming fee.

HelloRoam accepts Visa, Mastercard, American Express, Apple Pay, Google Pay, and PayPal. All transactions use 256-bit SSL encryption. Prices are shown in EUR for Irish customers. The final charge at checkout is processed in USD by our payment provider. Your bank converts the amount on its own. HelloRoam does not add any extra fees on top of the listed price.

HelloRoam city eSIM plans work on any carrier-unlocked, eSIM-compatible phone. iPhone XS and newer support eSIM natively. Samsung Galaxy S20 and newer also work. Google Pixel 3 and newer are compatible too. If your handset is locked to Eir, Three Ireland, or Vodafone IE, contact your carrier for an unlock before your city break. ComReg rules require all Irish carriers to provide unlocking free of charge once your contract term has ended.

HelloRoam eSIM New York plans connect to T-Mobile and AT&T networks across Manhattan, Brooklyn, and the wider metro area. New York is one of the most popular long-haul city break destinations from Ireland. Irish visitors get full 4G and 5G coverage with no Eir or Vodafone IE non-EU roaming add-on needed. Fixed plans start from 3GB for a short trip. Unlimited daily plans are available for longer stays or work trips.

Set up the HelloRoam city e-sim at home on your broadband the night before you fly. Open Settings, go to Mobile or SIM settings, tap Add eSIM or Add mobile plan, and scan the QR code from your HelloRoam order email. The profile downloads in under a minute. When you land at Heathrow, JFK, or Charles de Gaulle, switch the eSIM to active and your phone connects to local networks straight away. No airport SIM kiosk, no waiting, sorted in under 5 minutes.

HelloRoam city eSIM plans are data-only, so your Irish phone number stays active on your Eir, Three Ireland, or Vodafone IE SIM at the same time. Use WhatsApp or FaceTime over your HelloRoam data connection to call home for free. Your Irish contacts can still reach you on your normal number while you use local network speeds on your city break without paying a non-EU roaming rate.

HelloRoam city eSIM plans arrive by email within 2 to 5 minutes of purchase. Your QR code and setup instructions go straight to your inbox. Check your spam folder if the email does not arrive. You can also view and download your eSIM from your HelloRoam account dashboard at any time. No physical card gets posted out, so you can buy the night before your city break and still be sorted in plenty of time.

Data Sorted for Weekend City Breaks and Longer Stays

A city eSIM connects your phone to network coverage built around one metro area, whether that's a two-night break in Barcelona or two weeks based out of New York. HelloRoam offers plans for the cities Irish travellers actually fly into, on short direct routes and long-haul stops alike. This section covers how a city plan works and how to judge how much data an actual trip needs.

How a City Plan Covers the Ground You'll Actually Walk

A city eSIM connects you to the network covering that specific metro area, so a plan for Barcelona puts you on a network across the city and its transit lines, and a plan for New York does the same there. City trips tend to burn through more data than a quiet countryside trip, since maps, ride-hailing apps, and restaurant searches run pretty much non-stop from the airport onward. An e-sim built for city use accounts for that heavier pattern from the start. Fixed plans from around 3GB up to 20GB suit light to moderate use across a short break. An unlimited daily option suits anyone streaming from a hotel room in the evening or sharing a hotspot with a travel partner during a full day of sightseeing.

Choosing Between a Short Break and a Longer City Stay

A short break of three to five days, a weekend in Prague or a long weekend in Amsterdam, sits comfortably on a smaller fixed plan for maps, messages, and social media. A full week with some streaming mixed in fits a bigger fixed bucket. Anything longer, or heavier on data, calls for an unlimited daily plan instead. Each city plan page lists the local network name and expected speeds, so you can check coverage before you pay rather than guessing. A weekend in Vienna needs a different plan to two weeks in London, but the process stays the same either way: pick a data size, check out, scan the QR code. Every city plan lands by email and activates in a few minutes. The eSIM versus a physical SIM comparison matters most in cities where airport counters charge over the odds and still want ID before they'll hand one over. An e SIM skips both of those steps.

City eSIM plans give you local network data matched to how busy a city trip actually gets. Pick the destination, size the plan to how long you're staying, and activate before you fly. Your eSIM QR code lands by email, ready to connect the second your plane touches down.
