If you're flying from the UK to Dublin for a tech interview, a conference, or a long weekend in Galway, don't assume your UK plan will work. The Common Travel Area lets you move freely, but it doesn't guarantee free mobile data. Many UK providers treat Ireland as a roaming destination, which means daily fees or throttled speeds. A dedicated Ireland eSIM removes that risk.
If you're coming from India, for a master's at UCD, Trinity, or a job in the Silicon Docks, you need data on day one. You won't have a local address or bank account for a postpaid contract. An eSIM works immediately. And you can keep your Indian SIM active for bank OTPs while the eSIM handles your data.
Match your data to your habits, not your itinerary.
| Trip length | Light use (maps, WhatsApp) | Moderate (add social media) | Heavy (streaming, video calls) |
|---|---|---|---|
| 2-3 days | 1GB | 2GB | 3GB |
| 5-7 days | 3GB | 5GB | 10GB |
| 14+ days | 5GB | 10GB | 20GB |
Our curated plans start at 5GB for 30 days, from $2.59. That covers a week of moderate use with room to spare. If you're staying longer or tethering to a laptop, the 10GB and 20GB tiers are better value.
Dublin Airport: Wi-Fi is free but patchy in arrivals. Install your eSIM before you fly, so you have data the moment you land. You'll need it for the taxi app or to message your host.
Hotspot and OTPs: Use your Ireland eSIM as a hotspot for your laptop. Keep your home SIM active for SMS, especially if you're from India and need bank OTPs. Disable data on the home SIM to avoid roaming charges.
Buy the eSIM, scan the QR code, and you're done. It takes under two minutes. Data starts when you connect in Ireland, not before. Follow the setup guide for iPhone and Android if you get stuck.
No contracts, no registration at a shop, no paperwork. Just data on a major Irish network from the moment you arrive.
Get your Ireland eSIM, from $2.59 for 5GB.
Not necessarily. Ireland is not in the EU roaming zone for UK networks, despite the Common Travel Area. A UK plan may charge you roaming rates. A separate Ireland eSIM avoids this entirely.
For a 7-day trip with maps, WhatsApp, and light social media, 3GB is usually enough. If you plan to stream video or use video calls daily, go for 5GB or more.
Yes. Install the Ireland eSIM for data and keep your Indian SIM active for bank OTPs and SMS. You can disable data on the Indian SIM to avoid international roaming charges.
Data starts on your first connection to a network in Ireland. You can install the eSIM before you travel, but the 30-day validity period only begins once you land and connect.
Usually yes. Airport SIMs often have inflated prices and require registration. Our Ireland eSIM is delivered by email within a minute, and costs from $2.59 for 5GB.
Yes. You can use your Ireland eSIM as a hotspot for your laptop or tablet. Check your phone's hotspot settings after installing the eSIM profile.
For most trips a 5GB to 10GB data eSIM valid for 30 days is the right size: Slashtel's 5GB plan for Ireland is $5.69 on 3, Vodafone and Eir. Install it before you fly, keep your home SIM on for calls and bank texts, and top up the same eSIM if you run low.
If your phone supports eSIM, an eSIM is simpler than a local SIM card: nothing to collect at the airport, no passport registration, and your home SIM stays in the phone for calls and OTP texts. A physical SIM only makes sense for long stays where you need a local phone number.
From $2.59 for 1GB valid 7 days, as of 9 October 2026. Longer trips: two weeks from $3.59 (3GB), one month from $3.69 (3GB).
$0.74 per GB on the 50GB plan (180 days, $36.99). Bigger plans usually cost less per GB, so buy the size you expect to use.
3, Vodafone and Eir, with speeds up to 5G where available. The eSIM picks the strongest network automatically.
No. Slashtel eSIMs are data only, with no local number, calls or SMS. WhatsApp and other internet calls work, and your home SIM can stay on for calls and OTP texts.
Validity starts when the eSIM first connects to a network in Ireland, not when you buy it, so you can buy and install it before you travel.
After payment Slashtel emails a QR code within a minute. Scan it in your phone settings while on Wi-Fi at home, then switch on data roaming for the eSIM when you land.
Your phone must support eSIM and be carrier-unlocked. Dial *#06#: if an EID appears, the phone supports eSIM.
Yes. Hotspot and tethering are allowed on Slashtel eSIMs.
Pick a plan, pay by card. QR arrives by email within a minute.
