For a standard 3-7 day trip to Prague, most savvy travelers find 3GB to 5GB of mobile data to be a sweet spot. This covers essential navigation around Malá Strana, checking public transport schedules for the metro or trams, light social media, and messaging. If you're a heavy streamer, constantly uploading photos, or plan to use your phone as a hotspot, consider a plan with more GB. eSIMBuy always highlights the price-per-GB, so you can easily compare and pick a plan that fits your usage without shelling out extra for data you don't need.
