Install an Ireland eSIM: QR Code Steps for iPhone and Samsung

NoveSIM | Last updated on: October 7, 2026 | 6 minute read

Installing an Ireland eSIM means downloading the purchased profile onto your compatible phone. Use the installation details supplied with your order and a reliable internet connection; do not wait until you need data at the airport to discover that the profile has not been added.

Before installing early, check the package’s validity rules. Adding the profile, enabling a line and starting the package’s validity are different concepts, but the event that starts validity depends on the purchased plan.

Our travel eSIMs provide data. We do not provide an Irish number, conventional calls or SMS with these plans. Keep your existing SIM if you still need its services; adding the travel profile is not a request to transfer your home number.

Quick answer: Confirm that your phone supports eSIM and is unlocked, then open the order’s QR code on another screen. On iPhone, use Add eSIM → Use QR Code; on supported Samsung phones, use Connections → SIM manager → Add eSIM → Scan QR code. Complete the prompts and check that the new line appears. Follow the package’s activation instructions rather than assuming installation leaves validity untouched.

Prepare the order and the phone before scanning

If compatibility is uncertain, complete the Ireland eSIM phone checks first. A missing eSIM menu or a carrier lock should be resolved before attempting installation.

  • Connect the phone to reliable Wi-Fi or another working internet connection.
  • Read the installation method and activation timing in the order instructions.
  • Display the QR code on a second device or print it so the phone’s camera can scan it.
  • Keep any supplied manual installation details available, but do not invent missing fields.
  • Use the phone intended for the trip; do not scan the code on another device merely to test it.

Treat the QR code as private installation information. Do not post it publicly or send it in an unredacted screenshot.

Install the profile on iPhone

Apple documents QR-code installation in its cellular setup guide. Wording varies by region and iOS version, so your phone may say Mobile Data, Mobile Service or Cellular.

  1. Open Settings and the mobile service menu.
  2. Choose Add eSIM or Set Up Cellular, then Use QR Code. Some versions show this under Other Options.
  3. Scan the QR code provided for your order and follow the onscreen prompts.
  4. If a confirmation code is requested, enter only the code supplied by the provider.
  5. When setup completes, identify the new line and give it a clear label such as Ireland Travel.

Choose the order’s installation method, not an option to transfer your existing phone number from another iPhone. Keep the primary line’s role clear when the phone asks about default services.

Install the profile on a supported Samsung phone

Samsung’s Galaxy S23 series manual documents the QR-code route below. Other Android devices and software versions can use different labels; consult the instructions for your exact model rather than treating this as a universal Android path.

  1. Open Settings → Connections → SIM manager.
  2. Select Add eSIM, then Scan QR code.
  3. Scan your order’s code and complete the download prompts.
  4. Return to SIM manager and identify the newly added profile.
  5. Give the line a recognisable label and review which SIM is selected for mobile data.

If the menu is absent, stop and check compatibility or device restrictions. Repeatedly scanning the code does not add eSIM capability to an unsupported phone.

What confirms installation—and what does not?

The new profile appearing in the phone’s SIM settings is the useful installation check. Record its label so you can select the correct line later.

No Irish signal while you are still outside the package’s covered destination does not, by itself, establish a failed installation. Equally, a profile appearing in settings does not prove that data is active, that validity has not begun or that all settings are correct.

Review the timing rules for your Ireland eSIM package. When you are ready to connect under those rules, follow the Ireland activation guide for selecting the data line and the required roaming settings.

If the QR code fails or setup stops halfway

First check whether the profile already appears in SIM settings. Do not remove an installed or partially configured profile just because the final screen is unclear.

If the phone cannot read the image, display the complete code clearly on another screen. Use manual entry only when your order supplies the required installation fields. An APN is a data setting, not a substitute for a QR code or installation address.

For an “already used”, “invalid” or other error, keep the exact message and contact support with the order reference, phone model and whether a profile is visible. Avoid repeated attempts on different phones; do not assume the code is reusable after deletion.

If installation is complete but mobile data later fails in Ireland, use the connection troubleshooting guide. Our APN is data.esim when manual APN configuration is needed, but changing it does not repair an unsuccessful profile download.

FAQ

Can I install an Ireland eSIM before travelling?

Check the exact package’s instructions first. Early installation may be convenient, but do not assume validity starts only on arrival; the activation trigger is plan-specific.

How can I scan a QR code received on the same phone?

Display it on a second device or print it. Alternatively, use a supported same-device installation method or manual details only if the provider supplies them and your phone supports that method.

Do I need to remove my existing SIM?

No. Adding our travel eSIM is not a home-number transfer. Keep your primary SIM if needed and review the default data line and roaming settings separately.

Should I delete the profile and scan again after an error?

No. Check whether the profile is already present, retain it and send the exact error to support. Delete it only if support explicitly instructs you to do so.

Final Recommendation

Install your Ireland eSIM with reliable internet and the order instructions in front of you, after checking compatibility and the package’s validity trigger.

Confirm that the profile appears, label it clearly and keep your existing SIM’s settings separate from the travel line.

Move on to activation when the package instructions require it; if installation is uncertain, resolve the error without deleting the profile or testing the code on another phone.
