For a 5-day visit to Rome, a CoreESIM with 5-10 GB of data is generally adequate. This allocation supports daily navigation, moderate social media usage, email communication, light video streaming, and translation applications without constant reliance on Wi-Fi. Users engaging in extensive video consumption, frequent video calls, or mobile hotspot usage may necessitate a plan with a higher data ceiling.
