Dublin Airport Wi-Fi and Ireland eSIM Arrival Checklist

How do I get online in the terminal?

Dublin Airport’s official services page provides current Wi-Fi instructions. Use the airport’s named network and follow its connection steps. Airport Wi-Fi and a mobile eSIM are separate services; do not assume either connection will work everywhere.

Does a UK plan cover Dublin?

Do not assume so. Dublin is in Ireland; verify Ireland is explicitly listed on the selected product. For a journey continuing to Northern Ireland or Great Britain, check coverage for both countries rather than treating an itinerary as one mobile-data destination.

What should I prepare before leaving?

Save your pickup or transport booking, accommodation address and installation details. check your exact device, compare allowance/validity and read when the plan starts. These travel products provide data rather than ordinary carrier minutes or SMS. Check your primary SIM settings separately.

Use the walkthrough to see how buying in the Graba SIM app, installing on Wi-Fi and choosing your data line look on your own type of phone. Screens are illustrations: menu names vary by phone, software version and region.

Protect your home SIM from roaming charges

Switch roaming off on your usual line before you leave home, not after landing, so your phone cannot use your home provider’s roaming data when it first connects abroad. Then switch the travel eSIM on when you arrive.

• Before you fly, iPhone: Settings → Mobile Service (or Cellular) → your usual line → turn Data Roaming off. Keep mobile data on that line until you land.
• Before you fly, Android: Settings → Network & internet → SIMs → your usual SIM → turn Roaming off. On Samsung, start in Settings → Connections → SIM manager.
• When you land: open the travel eSIM line, make sure it is on and turn its Data Roaming (or Roaming) on. Then choose the travel eSIM for mobile data and turn off automatic data switching.

These settings control mobile data only. Your home provider may still charge for calls, texts or other services, so check its terms. Read the roaming settings guide.
