Best eSIM for Ireland: Real Prices Compared for Dublin, Cork and the Ring of Kerry

Ireland is one of those trips where you'll want data working the moment you land — Dublin Airport's arrivals hall isn't where you want to be hunting for wifi, and once you're driving the Ring of Kerry or the Wild Atlantic Way, mobile signal is often the only navigation you'll have. An eSIM lets you scan a QR code before you board and land already connected, no SIM-card counter required.

We checked live pricing across 123 providers we track for Ireland — as with every destination we cover, the price for the exact same amount of data varies enormously depending on who you buy from.

Quick-answer picks

• Shortest trip, light use: co:sim — a genuine unlimited day for $0.99.
• One week, moderate data: eSIMCard — 5GB for 7 days at $4.36.
• A standard month of data: nadanada — 10GB for 30 days at $7.99.
• Best for going unlimited: eSIMCard — unlimited data for 30 days at $22.75, less than half the price of Maya Mobile ($49.99) or Ubigi ($49.00).
• Best for long stays: Ubigi — 24GB spread across a full year (365 days) for $19.00 total.

Provider-by-provider breakdown

eSIMCard — the unlimited price-breaker

eSIMCard is the standout of everything we checked for Ireland: unlimited data for a full 30 days at $22.75, which isn't just the cheapest unlimited option we found, it's less than half of Maya Mobile's $49.99 and Ubigi's $49.00. Its metered tiers are just as sharp — 5GB for 7 days at $4.36, 10GB for 30 days at $8.22, and even a single day of unlimited at $1.74 if you just need to get through arrivals and check into your hotel.

nadanada — the simplest, cheapest ladder

nadanada runs a clean, predictable single-country ladder: $1.19 for 1GB over 7 days, $2.99 for 3GB over 30 days, $7.99 for 10GB over 30 days, up to $52.99 for 100GB over 30 days. There's no unlimited tier, but for anyone who just wants a fixed amount of data at the lowest realistic price, this is the ladder to check first.

co:sim — the cheapest way in

co:sim has one of the deepest Ireland catalogs of any provider we track, mixing Ireland-only tiers with regional Europe bundles. Its cheapest entry point is a genuine unlimited day at $0.99, and its Ireland-specific pricing climbs predictably through $7.99 for 5GB/30-days up to a 50GB/180-day plan at $59.99 for longer stays. Just check the single-country badge on each row before buying, since co:sim also lists dozens of pricier regional Europe options alongside its Ireland tiers.

Ubigi — built for long stays

Ubigi has by far the widest range of durations for Ireland, right up to a full year. Its standout is 24GB spread across 365 days for $19.00 total — worth knowing about if you split time between Ireland and elsewhere in Europe and want a SIM that's simply always live. Its Ireland-specific pricing is competitive too: 10GB for 7 days at $9.00, and a genuinely cheap unlimited/30-day plan at $49.00 — nearly tied with Maya Mobile, just edged out by eSIMCard.

Maya Mobile — the flat-rate baseline

Maya Mobile charges the same four-tier flat rate in Ireland as it does everywhere it operates: $9.99 for 3 days, $19.99 for a week, $27.99 for two weeks, $49.99 for 30 days, unlimited data throughout. It's a useful baseline for comparison — simple, no data-tier decisions to make — but Ireland is one of the destinations where a country-specific provider (eSIMCard) genuinely beats it on price.

Orbit Mobile — a simple monthly starter

Orbit Mobile keeps things minimal with five 30-day tiers, from $3.50 for 1GB up to $18.00 for 20GB. If your data needs are limited to maps and messaging and you don't want to compare a dozen duration options, this is about as straightforward as Ireland eSIM shopping gets.

Why prices vary so much for the same country

The gap between eSIMCard's unlimited-month price and Maya Mobile's or Ubigi's roughly similar figure for the same thing comes down to how the eSIM resale market actually works. Almost none of these providers operate their own network in Ireland — they buy wholesale roaming capacity from Irish or European carriers and resell it with a markup. That wholesale rate depends on which carrier a provider partners with and how much capacity they've committed to buying, which is also why the same provider's pricing can swing wildly country to country.

Pick by trip type

• Weekend in Dublin: co:sim's unlimited day at $0.99 or eSIMCard's 5GB/7-day plan covers maps, messaging, and photos without overpaying.
• A week-long road trip around the Ring of Kerry or Wild Atlantic Way: eSIMCard's 5GB/7-day at $4.36 or nadanada's 10GB/30-day at $7.99 gives enough headroom for offline-map downloads along remote stretches.
• A full month exploring the whole island: eSIMCard's unlimited 30-day plan at $22.75 removes any risk of running out mid-trip, at a fraction of what unlimited normally costs elsewhere.
• Splitting time between Ireland and the rest of Europe: Ubigi's 24GB/365-day regional plan is built for exactly that, not a short-trip plan stretched to fit.

Practical caveats

Most of the plans above are data-only, without voice minutes or SMS — fine for most travelers, since calls and texts typically run over WhatsApp or a similar app instead. If you specifically need a real phone number with voice/SMS included, check the "include voice & SMS plans" toggle on the Ireland plan list, since those plans are hidden from the default view.

Hotspot support isn't universal across every plan, so check the individual plan's details first if you're sharing your connection with a laptop or second device. And if you've never set up an eSIM before, it's worth a quick check that your phone actually supports one — our guide on checking eSIM compatibility walks through the settings-based way to confirm it.
