First Time in Greece? Here’s How to Get Internet on Arrival

Greece is a trip of islands, and islands mean ferries, flights and a lot of moving around. Acropolis tickets, ferry bookings, rental scooters and sunset spots in Santorini all depend on your phone. Roaming rates add up across a long island-hopping itinerary. A travel eSIM keeps you connected without hunting for a SIM shop. Here is how to pick the best eSIM for Greece and where signal fades.

Which networks will my eSIM use in Greece?

Greece has three networks — Cosmote, Vodafone and Nova. Cosmote has the widest coverage, including many islands and mountain villages. All three run good 4G, with 5G in Athens, Thessaloniki and larger islands.

A travel eSIM roams across the networks and picks the strongest signal, which matters when you move between islands.

How much data do I need for a Greece trip?

Greek trips often mix a city with several islands.

• Athens plus one island (5-6 days): 1-2 GB a day.
• Island-hopping for ten days: 8-12 GB in total.
• Hire car or scooter with live navigation, or tethering: 15 GB or an unlimited plan.

Ferry tickets, ticket QR codes and map navigation make Greece more data-hungry than it first looks.

Coverage on the routes people actually take

Athens, Thessaloniki, Rhodes, Heraklion: excellent 4G and 5G.

Santorini and Mykonos: strong in Fira, Oia and Mykonos Town, with dips in cliffside spots and quiet beaches.

Crete: good in cities and resorts, with no signal inside Samaria Gorge and gaps on mountain roads.

Meteora and mainland villages: generally fine around the monasteries and towns.

Ferries: signal near ports and coasts, dropping out mid-sea on longer crossings.

What you will use data for in Greece

• Ferry tickets and live schedules, which change with weather and winds.
• Timed entry for the Acropolis, where slots sell out in summer.
• Maps for scooter and quad rentals, and for finding the beach you saw on Instagram.

How to set up your Greece eSIM

1. Check your phone is eSIM-compatible and carrier-unlocked.
2. Buy your Greece eSIM on eSIMify. The QR code arrives by email within seconds.
3. Scan the QR before you fly. Validity only starts when the eSIM first connects to a network in Greece.
4. Arrive at Athens (ATH), Santorini (JTR) or Heraklion (HER), switch on data roaming for the eSIM line, and you are online.

Why eSIMify works well for Indian travellers

Prices in rupees, payment by UPI, RuPay or card, and support on Indian time. There is no forex markup and no dollar-denominated charge appearing on your card weeks later.

Greece is in the EU and Schengen area, so most Europe plans include it. If you are also visiting Turkey or Albania, check the plan's country list.

Frequently asked questions

Does my Indian number still work in Greece?
Yes. Your Indian SIM stays active for calls and OTPs while the eSIM handles data. Keep data roaming off on the Indian line.

Does the eSIM work on Greek ferries?
Partly. Expect signal near ports and the coast, and gaps in open water.

Does it work in Santorini?
Yes. Coverage is good in Fira, Oia and Kamari, with dips in remote cliff spots.

Will it work in Samaria Gorge?
No. There is little to no signal inside the gorge, so download maps beforehand.

How much data for 10 days in Greece?
8-12 GB suits most island-hoppers.
