What data volume (GB) is recommended for a 5-day itinerary in Athens using CoreESIM?

For a 5-day excursion in Athens, encompassing navigation through Plaka, accessing information on sites like the Acropolis, utilizing ride-sharing applications, and moderate social media engagement, a CoreESIM plan offering 5-10 GB of data is generally sufficient. This allocation supports extensive LBS (Location-Based Services) and data-intensive applications without frequent Wi-Fi dependency. Users planning high-definition streaming or significant tethering should consider the upper end of this range for optimal performance.
