Greece
A Greece travel eSIM roams onto Cosmote or Vodafone GR, with Cosmote generally the stronger choice once you leave the mainland. Install the profile before you fly and note that "unlimited" plans run full speed only to a daily cap before throttling.

- When you land
- Install the eSIM and scan the QR code at home on your own Wi-Fi, before you board, so you are not depending on airport connectivity — particularly if you are flying into one of the small island airports where the arrivals hall Wi-Fi may be the only Wi-Fi you get. On landing, turn off airplane mode, set the eSIM as your mobile data line, and confirm Data Roaming is ON for that line; expect to register on Cosmote or Vodafone GR within a minute or two.
Common questions
- Does an eSIM work in Greece?
- Yes. Greek networks fully support roaming eSIM profiles, and yours will register on Cosmote or Vodafone GR like any visitor's phone. You need an eSIM-capable, carrier-unlocked handset. Install and test the profile at home before you fly, then enable data roaming for that line after you land.
- Will my eSIM work on the ferries between islands?
- Partly. You will usually have a usable signal while the coastline is close, then lose it across open water and pick it back up approaching the next island. On longer Aegean crossings expect an hour or more with nothing. Download your tickets, maps and anything to read before boarding rather than counting on onboard Wi-Fi.
- How much data do I need for ten days in Greece?
- Maps, messaging, ferry and booking apps, browsing and translation come to roughly 300 to 500 MB a day, so 5 GB covers a typical ten-day trip. Add more if you stream on long ferry legs or upload high-resolution photos. Hotel and taverna Wi-Fi is common and takes real pressure off the plan.
