Why Get an eSIM for Greece?
- Track ferries on the go. Schedules change with the weather, and updates usually come by app or text.
- Online from Athens Airport, ready for the metro or a taxi to the port.
- Keep your number for booking confirmations and bank codes.
- Avoid roaming fees if your carrier is outside the EU.
How to Choose a Greece eSIM
Trip length
Pick a plan that covers your whole stay plus a spare day for flight times. egoViet plans can't be topped up, so it is better to size up than to run short. If your high-speed data does run out, you stay online at a basic speed of around 128 kbps, enough for messaging.
How much data you use
Maps, ferry apps, and messages use little data. Sunset videos from Oia and video calls use much more. Here is a guide to how much data you need when you travel.
Where you are going
For Greece alone, a Greece eSIM is the best value. If you are also visiting Italy, Turkey, or Cyprus, see the Europe eSIM below.

Tips for Staying Connected in Greece
- Book ferries online and check for weather changes, especially when the summer meltemi winds pick up.
- Signal can drop at sea between islands. Download tickets and maps before boarding.
- Smaller islands have fewer masts. Coverage is good in main villages but weaker on remote beaches and hiking trails.
- Buy Acropolis tickets in advance and arrive early to avoid the heat and the crowds.
- Need to call? egoViet eSIMs are data-only, so use WhatsApp or FaceTime. Here is how calling works with a data-only eSIM.
