How to verify eSIM support on your device

1. iPhone: Settings → Cellular → look for "Add eSIM" or "Add Cellular Plan". You can also dial *#06# , if you see an "EID" (32-digit number), your phone has eSIM hardware.
2. Android: Settings → Connections (or Network & Internet) → SIM Cards → look for "Download a SIM instead" or "Add eSIM".
3. EID check: most eSIM-capable Android phones show EID in Settings → About Phone → Status.

Tip: Even if your phone supports eSIM hardware, it must be unlocked (not carrier-locked) to use third-party eSIMs like Cellesim. Most phones bought outright are unlocked; phones from carrier instalment plans may require unlocking after the contract is paid off.

Almost every flagship smartphone released since 2019 supports eSIM, making it ideal for international travel. Compatible models include iPhone XS and newer, Google Pixel 3 and newer, Samsung Galaxy S20 and newer, plus a growing list of mid-range devices. If your phone has Settings → Cellular → "Add eSIM", you're ready to use a Cellesim plan abroad.

Travellers benefit most from eSIM because it eliminates the airport SIM-card queue, removes the need to swap your home SIM out, and lets you keep your usual phone number active for SMS verification. A Cellesim travel eSIM activates the moment you land , no shop visit required.

4. Android version: Android 9 or newer typically supports eSIM, though it depends on the manufacturer.
5. Region-specific variants: some Samsung models sold in Hong Kong or China are dual physical SIM with no eSIM , verify your specific model number.

Tip: if your current phone doesn't support eSIM but you travel often, an unlocked, mid-range eSIM-capable phone (e.g., Pixel 7a, iPhone SE 3, Samsung Galaxy A55) makes an excellent secondary travel device , pair it with a Cellesim plan and you have a full mobile internet kit for any destination.

 This specific plan is valid only within the Republic of Ireland (or, if it's a regional plan, you'd say "Yes"). This is the most important question. If you drive from Dublin to Belfast (Northern Ireland), your connection will stop at the border as it is part of the UK (non-EU). For a seamless all-island trip, we highly recommend our Europe Regional eSIM (which must include the UK). 

It depends.

• If you are from the UK (Post-Brexit): Most UK carriers (like O2, Vodafone, Three, EE) have reintroduced daily roaming fees (e.g., £2-£6 per day) for Ireland.
• If you are from the USA/Canada/Asia: Your home carrier will charge expensive international rates (e.g., $10-$14 per day).

A Cellesim eSIM is a one-time prepaid fee that is significantly cheaper than these roaming charges.

Yes, absolutely. This is the #1 coverage question. Our eSIM connects to premium networks (like Vodafone/Eir) that provide strong 4G/LTE coverage not just in Dublin, but on all major tourist routes, including the Cliffs of Moher, the Ring of Kerry, and the Dingle Peninsula. You will have a signal for Google Maps on the scenic drives. 

Yes, 100%. Buying a physical "prepaid" SIM at Dublin Airport (from Eir or Vodafone) requires you to find the kiosk (WHSmith, Spar), wait in line, and go through a mandatory passport registration process as required by EU law. Our eSIM is 100% digital, requires no ID registration, and can be installed before you fly, so you are connected the moment you land. 

Our Ireland eSIM connects to premium Tier-1 networks, typically Vodafone Ireland or Eir, ensuring excellent speed and coverage across the country.

We partner with these top-tier providers to give you reliable mobile data wherever your travels take you in Ireland. Vodafone Ireland is widely recognized for offering the best and most extensive network coverage. This is particularly beneficial for travelers exploring the remote rural and stunning coastal areas of the West, meaning you're more likely to stay connected even off the beaten path.

While Vodafone is often highlighted for its reach, Eir also provides robust service, especially in urban centers and major tourist destinations. Our eSIM automatically connects to the strongest available signal from these premium networks, ensuring you always have access to high-quality data. This approach helps address common concerns for travelers looking for reliable connectivity, whether they are considering a Vodafone eSIM for Ireland or checking if Eir supports eSIMs for their trip.

 Most modern phones do, but you must check our specific list here: eSIM Compatible Devices to be 100% sure before purchasing. 

 Scan it at home before your flight. This ensures you get immediate data the moment you land at Dublin Airport (DUB) or Shannon without searching for free WiFi. 

 Connect to any hotel or pub WiFi in Dublin or Cork and contact our 24/7 support via WhatsApp or Email immediately. 

 Yes. Free Now is the main taxi app in Ireland (Uber is limited), so having reliable data is essential to get around safely. 

 Yes. Coverage is generally good in Glendalough and the Wicklow Mountains, but signal may drop in deep valleys or heavy forests. 

 Yes. You will have signal at Rossaveel and on Inis Mór, but the connection might drop briefly during the ferry crossing in Galway Bay. 

 Mostly yes. While thick historic stone walls in Temple Bar can block signals, our eSIM connects to strong low-frequency bands to maintain coverage indoors.
