For a 5-day trip to Rome, a Cellesim eSIM with 5-10 GB of data is usually sufficient. This allows for daily navigation, social media use, checking emails, light streaming, and using translation apps without constantly searching for Wi-Fi. If you plan heavy video streaming or hotspot usage, consider a 15-20 GB plan.
