- A week away, standard use: Social media, music and some video fit 5 GB for 7 days. Start in London, visit Edinburgh, then fly across to Dublin and Cork, all on the same eSIM.
- Two weeks, heavy use: Streaming and hotspot use fit 50 GB for 180 days. Fly into Manchester (MAN), then Shannon (SNN), and explore Killarney and Dingle at your own pace.
- Ireland only: If Ireland is your only stop, the Ireland eSIM is the one for that trip.
