For a typical 3-5 day exploration of Dublin, we generally recommend budgeting 3-5 GB of mobile data. This allocation comfortably supports essential activities like navigating to landmarks such as Dublin Castle or the Guinness Storehouse, engaging with social media, messaging, and light web browsing. If your itinerary includes extensive streaming, frequent video calls, or using your device as a hotspot, consider a larger data package—perhaps 10 GB—to ensure uninterrupted connectivity for all your route-planning needs.
