How much mobile data do we need for a group trip to Prague?

For a typical 3-7 day group trip to Prague, a Triply shared data plan with 3GB to 5GB per person is usually a good amount. This covers daily navigation around the Charles Bridge, checking public transport schedules (like the efficient metro or trams), light social media use to share group photos, and messaging while exploring neighborhoods like charming Malá Strana or vibrant Vinohrady. If your group includes heavy streamers or plans extensive video calls, opting for a larger Triply shared data plan will keep everyone smoothly connected throughout your Czech adventure.
