Installation

Ireland eSIM setup walkthrough

iOS installation (iPhone)

Open Settings > Cellular > Add eSIM
Select "Use QR Code"
Scan the QR code from your Nomad confirmation email
Label the plan (e.g., "Ireland Travel")
Set as cellular data line (not your default for calls)
Do NOT enable data roaming yet
Confirm the plan appears under Settings > Cellular

iOS 18: the "Add eSIM" option appears under Settings > Cellular > Add Cellular Plan. iOS 17 and earlier: Settings > Cellular > Add eSIM.

Android installation (Google Pixel)

Open Settings > Network & Internet > Add eSIM
Select "Download a SIM instead" then scan
Scan the QR code from your Nomad confirmation email
Name the profile (e.g., "Ireland Data")
Set as mobile data SIM
Do NOT enable data roaming yet
Verify the plan in SIM manager

Manual installation (if QR fails)

If the QR code does not scan, use manual entry:

Go to Settings > Cellular > Add eSIM
Select "Enter Details Manually"
Enter the SM-DP+ address from your provider email
Enter the activation code
Complete the setup as with the QR method

Use manual entry when: camera cannot read the QR code, the email was forwarded without the image, or you are installing on a second device.

Configuration

Configuring APN for Ireland data

Automatic APN configuration

Most eSIM profiles auto-configure APN settings for Eir's network. After installation, verify the APN is set correctly:

iPhone: Settings > Cellular > Cellular Data Options > Cellular Data Network
Android: Settings > Network & Internet > SIMs > (travel eSIM) > Access Point Names

A correctly configured APN shows the carrier name and data type. If the APN field is blank, your phone will attempt to auto-fill on first connection.

Manual APN entry

If auto-configuration fails (rare, typically older Android devices), enter APN settings manually. Check your provider's confirmation email for the exact values. Common fields:

APN configuration fields
Field	Value
APN Name	From provider email
APN	Provider-specific value
Authentication	None (most providers)
APN Protocol	IPv4/IPv6

Provider-specific APN values override Eir's carrier defaults. Always use the values from your provider, not generic carrier APNs.

5G and LTE band selection

5G is available in Ireland (widespread coverage). To force a network type:

iPhone: Settings > Cellular > Cellular Data Options > Voice & Data > 5G Auto / LTE
Android: Settings > Network > Preferred network type > 5G/LTE/3G Auto

Switch to LTE-only to conserve battery in rural areas without 5G towers. 5G in Dublin, Cork, Galway, and expanding to smaller towns

Verification

Speed test and signal check for Ireland

Signal and network verification

Check your status bar: the carrier name should show Eiror a roaming indicator. Signal bars confirm connection strength. Go to Settings > Cellular to verify data usage is counting on the travel eSIM line.

"Eir" or roaming icon: Connected and working
"Searching...": Still connecting, wait 2-3 minutes
"No Service": Data roaming is off or wrong SIM line selected

Speed test

Run fast.com or Speedtest.net to verify your connection speed. Expected speeds on Eir: approximately 120 Mbps download. Speeds vary by location: airports and city centers are fastest, rural areas slower.

Verifying data roaming is active

Go to Settings > Cellular > (travel eSIM) > Data Roaming: ON. Test by opening any website in your browser. If it loads, roaming is active. If not, toggle data roaming off and back on, then restart your phone.

Dual-SIM verification

Confirm your home SIM still receives calls and texts. Confirm the travel eSIM handles all data traffic. Test: send yourself a text message to your home number. Then load a webpage. Both should work simultaneously. If data routes through the home SIM instead, switch your cellular data line to the travel eSIM.

Airport Guide

Arriving at Dublin (DUB) with your eSIM

Before boarding

The night before your flight, open Settings, add a new eSIM, and scan the QR code from your order email. Your home WiFi provides the clean connection the download needs. After it installs, switch the Ireland profile to off. Leave it dormant until wheels touch the runway. Eir picks up the signal within 60-90 seconds of your phone leaving airplane mode.

During the flight

Keep airplane mode on during the flight. Confirm your Ireland eSIM is set as the designated data line under Settings before you descend. Your home SIM stays active for calls and SMS verification codes.

After landing

Once the seatbelt sign is off, disable airplane mode and enable the Ireland eSIM. Eir registers the profile in 30-45 seconds. You have maps, messaging, and ride-share access before the cabin door opens. The SIM counter from Eir and Vodafone is in the arrivals hall — expect a 5-10 min wait and $10-20 for 10-30GB / 28 days for a tourist plan. Walk past it.

Leaving the airport

Your eSIM is working. Open your ride-share app and request a pickup while you wait at baggage claim. By the time your bag arrives, the car is already en route. No WiFi hunting, no SIM counter, no wasted minutes. Ireland's emergency number is 112/999 — it works without data, but having your eSIM active means you can also share GPS coordinates with emergency services.

Device Setup

Device-specific instructions for Ireland

iPhone (iOS 17+)

Open Settings > Cellular > Add eSIM > Use QR Code.
Point the camera at the QR code from your provider's email. The profile downloads in 5-15 seconds on stable WiFi.
Tap "Add Cellular Plan" when prompted. Label the plan "Ireland Data" to distinguish it from your home line.
Go to Settings > Cellular > Cellular Data and select the Ireland eSIM as your active data line.
Turn on Data Roaming for the Ireland line only: Settings > Cellular > [Ireland Data] > Data Roaming > On.
After landing at Dublin (DUB), toggle the eSIM on. Eir registers your profile in 60-90 seconds. APN settings auto-configure for most Ireland eSIM plans on Eir's network.
Verify: open Safari and load any webpage. If the page renders, your Ireland data is active at 120 Mbps average.

Carrier confirmation: Your status bar should display "Eir" or "Vodafone IE" with 5G/LTE signal within 60-90 seconds. On iPhone, check Settings > Cellular — the Ireland line shows "Eir" under Network. If you see "5G" in the status bar, your phone has connected to Eir's 5G band.

Note: If the carrier field shows "No Service" after 2 minutes, go to Settings > Cellular > Network Selection, turn off Automatic, wait 10 seconds, then turn it back on. If Eir does not appear in the list, restart your iPhone (hold Side + Volume Down for 3 seconds, slide to power off, wait 30 seconds, power on).

Samsung Galaxy (One UI 6+)

Open Settings > Connections > SIM Manager > Add eSIM.
Select "Scan QR Code" and frame the QR code from your provider's email. The download completes in 5-15 seconds.

Enable Data Roaming: Settings > Connections > Mobile Networks > Data Roaming > On (for the travel SIM only).
After landing at Dublin (DUB), enable the eSIM. Eir's 5G/LTE network registers within 60-90 seconds. APN settings load automatically for most Ireland eSIM plans on Eir's network.
Verify: open Chrome and load any page. Data flowing confirms your Ireland eSIM is active.

Carrier confirmation: Your status bar should display "Eir" or "Vodafone IE" with 5G/LTE signal within 60-90 seconds. On Samsung, check Settings > Connections > SIM Manager — the travel SIM shows "Eir" as the connected network. A "5G" icon in the status bar confirms Eir's 5G connection.

Note: If "No Service" persists after 2 minutes, go to Settings > Connections > Mobile Networks > Network Operators, switch from Automatic to Manual, wait for the scan to complete, then select Eir. If the carrier does not appear, restart the device: hold Power + Volume Down until the restart menu appears.

Google Pixel (Android 14+)

Open Settings > Network & Internet > SIMs > Add SIM > Download SIM.
Scan the QR code from your eSIM provider's email. The profile downloads in under 15 seconds.
Confirm the download and label the SIM "Ireland Data" for identification.
Set as mobile data SIM: Settings > Network & Internet > SIMs > Ireland Data > Use for mobile data.
Enable roaming: Settings > Network & Internet > SIMs > Ireland Data > Roaming > On.
After landing at Dublin (DUB), enable the profile. Eir connects within 60-90 seconds. APN settings self-configure on Pixel devices for most Ireland plans.
Open Chrome and load any page to verify data connectivity on Eir's 5G/LTE network.

Carrier confirmation: Your status bar should display "Eir" or "Vodafone IE" with 5G/LTE signal within 60-90 seconds. On Pixel, check Settings > Network & Internet > SIMs — the travel SIM displays "Eir" as the active network.

Note: If the signal does not register within 2 minutes, go to Settings > Network & Internet > SIMs > Ireland Data > Advanced > Choose network, switch to Manual, let the scan run, and select Eir. If it fails, reset network settings under Settings > System > Reset options > Reset Mobile, WiFi & Bluetooth.

Carrier Config

Carrier troubleshooting for Ireland

Eir

Network selection: Open Settings > Cellular > Network Selection (iPhone) or Settings > Connections > Mobile Networks > Network Operators (Samsung). Turn off Automatic. Wait 10-30 seconds for the carrier list to populate. Select "Eir" from the list. The phone locks onto Eir's 5G/LTE band and data resumes within 30 seconds.

Expected speed: 108-120 Mbps in urban areas, 36-60 Mbps in rural coverage

Common issue: If Eir connects but web pages time out, the phone may have defaulted to your home SIM for data. Go to Settings > Cellular > Cellular Data and confirm the Ireland eSIM is selected. The home SIM handles calls only.

Resolution: Contact your eSIM provider's support with the SM-DP+ activation address from your confirmation email. Some Eir profile issues require a new QR code. Airalo responds via in-app chat in under 5 minutes; Holafly offers WhatsApp support at +34 644 44 37 97.

Vodafone IE

APN: "live.vodafone.com" — enter under Settings > Cellular > Cellular Data Network (iPhone) or Settings > Connections > Mobile Networks > Access Point Names (Samsung). Leave username, password, and proxy fields blank. Save and restart data.

Network selection: Open Settings > Cellular > Network Selection (iPhone) or Settings > Connections > Mobile Networks > Network Operators (Samsung). Turn off Automatic. Wait 10-30 seconds for the carrier list to populate. Select "Vodafone IE" from the list. The phone locks onto Vodafone IE's 5G/LTE band and data resumes within 30 seconds.

Expected speed: 72-102 Mbps in cities, 24-48 Mbps outside metro areas

Common issue: Vodafone IE's network occasionally delays eSIM profile registration during peak hours at major airports. If your phone shows "Searching..." for more than 2 minutes, turn off Automatic network selection, wait 10 seconds, then select Vodafone IE manually from the operator list.

Resolution: Restart your phone after adjusting network settings. Vodafone IE typically completes registration within 60-90 seconds of a fresh boot. If the issue persists, remove and re-add the eSIM profile using the manual activation code from your provider's confirmation email.

Three Ireland

APN: "three.co.uk" — enter under Settings > Cellular > Cellular Data Network (iPhone) or Settings > Connections > Mobile Networks > Access Point Names (Samsung). Leave username, password, and proxy fields blank. Save and restart data.

Network selection: Open Settings > Cellular > Network Selection (iPhone) or Settings > Connections > Mobile Networks > Network Operators (Samsung). Turn off Automatic. Wait 10-30 seconds for the carrier list to populate. Select "Three Ireland" from the list. The phone locks onto Three Ireland's 5G/LTE band and data resumes within 30 seconds.

Expected speed: 72-102 Mbps in cities, 24-48 Mbps outside metro areas

Common issue: Some eSIM plans routed through Three Ireland require data roaming to be enabled on the travel SIM line specifically. Leaving it off is the most common reason travelers report zero signal after landing in Ireland. Check under Settings > Cellular > [Travel eSIM] > Data Roaming.

Resolution: Toggle airplane mode on for 15 seconds, then off. This forces a fresh network scan without a full restart. Three Ireland should appear in your carrier field within 60 seconds. If it does not, use manual network selection to find and choose Three Ireland directly.

Dual SIM

Ireland dual SIM guide: eSIM for data, home SIM for texts

Data line setup

Under Settings > Cellular > Cellular Data, choose the Ireland travel eSIM. Disable "Allow Cellular Data Switching" to prevent your phone from routing data through the home SIM when Eir's signal dips temporarily. A brief signal dip is normal when moving between cell towers — your home carrier's roaming rates are not a reasonable fallback.

Calls and SMS

Maintain your home SIM for voice and SMS. Your number does not change. Authentication codes still arrive by text. The Ireland eSIM is data-only: all apps, browsing, maps, and data-based messaging use Eir's 5G/LTE connection. This split keeps costs controlled — home carrier voice rates are typically lower than international data roaming.

Emergency dialing

Emergency calls work on any active SIM, even without a data plan. In Ireland, dial 112/999 from either SIM line. If your eSIM has data active, you can also share your GPS location with emergency services via messaging apps or the phone's built-in emergency SOS feature.

Battery impact

Dual SIM operation increases battery consumption by roughly 10-15%. Both the home SIM and Ireland eSIM maintain active connections to separate towers. To conserve battery, switch the home SIM to airplane mode when you do not need incoming calls. Data on Eir continues normally through the eSIM. Pack an adapter for Ireland's Type G sockets.

Hotspot

Hotspot configuration for Ireland travelers

Your Ireland eSIM data can be shared via personal hotspot. iPhone: Settings > Personal Hotspot. Samsung: Settings > Connections > Mobile Hotspot and Tethering. The connected device sees Eir's 5G/LTE signal at 72-96 Mbps typical through hotspot. Data consumption through hotspot runs 1.5-2x higher than direct phone use because laptop browsers load full desktop sites. Budget accordingly — a 1GB plan at $2.76 supports 2-3 days of moderate laptop use.

Provider restrictions

Provider-level restrictions: Airalo includes hotspot on nearly all fixed-data plans. Saily allows tethering by default. Holafly restricts it on unlimited Ireland plans. Nomad permits tethering on most tiers. If the hotspot toggle does not appear in Settings after installing your Ireland eSIM, the plan does not support it — upgrade or switch providers.

Data impact

Tethered devices consume data faster than direct phone use. A laptop loading desktop websites uses 2-3x the data of mobile sites. Video streaming at 720p burns 1.5 GB per hour; at 1080p, closer to 3 GB. Cloud sync (Google Drive, Dropbox, iCloud) runs in the background and can drain 500 MB-1 GB in a few hours without visible activity. Pause cloud sync before connecting a laptop to your Ireland hotspot.

Peak Season

Ireland peak season: Jun-Aug network advisory

During Jun-Aug, Ireland's tourist areas push Eir's network capacity. Speeds drop to 48-72 Mbps during peak congestion in popular locations during afternoon and evening hours. Early morning (6-9 AM local) typically delivers full-speed connectivity. Buy your eSIM early — price increases during peak season are rare for eSIMs but common at airport SIM counters.

Connect to Ireland's 5G network via eSIM

Ireland's Eir network provides widespread 5G coverage across major cities and airports. 5G in Dublin, Cork, Galway, and expanding to smaller towns. Your eSIM connects to 5G automatically if your device supports it. To force 5G: iPhone — Settings > Cellular > Voice & Data > 5G On. Samsung — Settings > Connections > Mobile Networks > Network Mode > 5G/LTE. Choose "5G Auto" to balance speed and battery life. Eir delivers 120 Mbps average on 5G bands. Outside 5G coverage areas, the phone falls back to LTE without interruption.

WiFi Backup

Activate your Ireland eSIM without reliable WiFi

Public WiFi in Ireland is good. Free WiFi in most pubs, cafes, and hotels. For eSIM installation, use your home WiFi before departure. The QR code scan downloads a small profile (under 1 MB) from the carrier's server. This transfer needs a clean connection — captive portals and login walls at Dublin (DUB) or hotels can interrupt it.

Activating without WiFi

Fallback if WiFi is unavailable: manual SM-DP+ entry. Your confirmation email from the eSIM provider includes a server address and activation code. iPhone: Settings > Cellular > Add eSIM > Enter Details Manually. Samsung: Settings > Connections > SIM Manager > Add eSIM > Enter Activation Code. This method works over any internet connection. Save the email offline before departure so you have the codes even without connectivity.

Multi-Country

Adding Ireland to your multi-country eSIM setup

Multi-country travelers benefit from per-country eSIM profiles. A dedicated Ireland plan on Eir runs faster than a regional eSIM because it connects to the local network directly instead of roaming. Install all profiles at home, label them by country, and switch at each border. iPhone stores 8 profiles; newer Samsung devices store 10 or more. Ireland plans start at $2.76 for 1GB.

Switching eSIM profiles between countries

To switch from a previous country's eSIM to Ireland: iPhone — Settings > Cellular, tap the old country's eSIM, toggle "Turn On This Line" off. Tap the Ireland eSIM, toggle it on, and confirm it is set as Cellular Data. Samsung — Settings > Connections > SIM Manager, disable the old SIM, enable the Ireland SIM, set it as Mobile Data. Eir registers within 60-90 seconds.

Fixes

Solving Ireland eSIM issues

"eSIM Not Supported" error

Cause: Your phone is carrier-locked or the model does not support eSIM.

Fix: Contact your home carrier to unlock (24-72 hours). Verify your model supports eSIM at our compatibility list.

"Unable to Activate eSIM" error

Cause: eSIM profile slot is full, or the QR code was already redeemed.

Fix:Delete unused eSIM profiles in Settings > Cellular. iPhones hold 8 profiles (2 active). If the QR shows as used, contact your provider for a replacement code.

Connected but no data

Cause: Data roaming is off on the travel eSIM, or data is routing through the home SIM.

Fix:Settings > Cellular > select travel eSIM > Data Roaming ON. Also verify: Settings > Cellular > Cellular Data > select the travel eSIM as your data line. Restart your phone after making changes.

Slow speeds on Eir

Expected: 120 Mbps. If speeds are noticeably lower: toggle airplane mode on and off. Move to a different area. Try forcing LTE if 5G is congested. During Jun-Aug speeds may drop in tourist areas.

Provider-specific installation issues

Airalo: QR code in email and in-app. Re-download available in the app under "My eSIMs"
Nomad: QR delivered by email only. Check spam folder. No app required for installation
Holafly: QR code in app and email. Unlimited plans activate on first connection
