How much data do I need for a week at Venice Carnival?

For a week-long trip to Venice Carnival, a 5-10 GB data plan is a solid choice for most travelers. This covers daily navigation with Google Maps, using the Vaporetto schedule app, sharing photos and videos on social media, and staying in touch via messaging apps. If you plan to upload a lot of high-resolution video or use your phone as a hotspot for other devices, consider a 15-20 GB plan to ensure you don't run out.
