For a 5-day trip exploring Athens' historical sites like the Acropolis, navigating Plaka, and using social media, 5-10 GB of data is usually sufficient. This allows for extensive map usage, ride-sharing apps, browsing, and occasional video streaming without constantly searching for Wi-Fi. Cellesim offers various plans to match your data needs.
Yes, Cellesim eSIMs typically connect to major Greek mobile networks like Vodafone GR, Cosmote, or Nova (formerly Wind Hellas), offering excellent 5G and 4G LTE coverage throughout Athens. You can expect fast speeds for streaming and browsing in central areas like Syntagma Square, Monastiraki, and even on the metro lines.
Absolutely! It's highly recommended to purchase and set up your Cellesim eSIM before you even leave home. After buying your plan online, you'll receive a QR code via email.
