Best eSIM for Americans visiting Greece โ€” complete guide

25 July 2026ยทProost eSIM

Greece is a dream destination โ€” but hotel wifi is notoriously unreliable

Santorini, Mykonos, Athens โ€” Greece draws millions of Americans every year. And wifi in Greek hotels and cafes is notoriously slow. Mobile data is your friend.

The Europe eSIM covers Greece plus 30+ countries

If Greece is part of a broader European trip, one Proost Europe eSIM covers your entire itinerary โ€” France, Italy, Spain, Croatia and more.

Coverage

Greece has solid 4G on the mainland and major islands. Athens, Santorini, Mykonos, Corfu, Crete and Rhodes all have good signal. Smaller remote islands may have limited coverage.

How much data?

  • 5GB โ€” one week
  • 10GB โ€” two weeks or island hopping
  • 20GB โ€” extended trip or heavy users
  • The AUD advantage for Americans

    $10 AUD costs approximately $6.50 USD at current rates โ€” meaningful savings versus US-based providers.

    Tips for US visitors

  • Download offline Google Maps for each island โ€” no wifi on ferries
  • Use Ferryscanner or Ferryhopper apps for ferry bookings โ€” both need data
  • Wise or Revolut cards save on ATM fees throughout Greece
