What is the optimal mobile data allowance for a week in Paris with CoreESIM?

For a typical 5 to 7-day visit to Paris, CoreESIM recommends a data plan ranging from 7 GB to 12 GB. This allocation is sufficient for daily navigation to landmarks like the Eiffel Tower, use of ride-sharing platforms, social media engagement, and light browsing without constant reliance on public Wi-Fi. For users who anticipate extensive video streaming, large application downloads, or frequent tethering, a 15 GB or 20 GB plan would provide a more robust data ceiling.
