A typical 3-5 day trip to Dublin usually requires 3-5 GB of mobile data. This amount supports navigation, social media, messaging, and light browsing while exploring landmarks like Dublin Castle or the Guinness Storehouse. If you plan extensive streaming or video calls, consider a larger 10 GB package for peace of mind.
