Greece eSIM for Canadians: Athens, Santorini and Islands (2026)

The best Greece eSIM for Canadians is a prepaid, data-only plan that runs on more than one Greek 5G network and installs on your phone before you fly. It costs far less than the $16 to $18 a day that Bell, Rogers and Telus charge for roaming in Greece, and one plan covers Athens, Santorini and every other island on your route.

Greece trips tend to move around: a couple of days in Athens, then ferries between the Cyclades or a flight to Crete or Rhodes. That is a lot of bookings, maps and ferry notices to manage from your phone. This guide covers what roaming in Greece costs, how the three Greek networks compare, what to expect when island hopping, how much data you need and how to set up your eSIM.

How much does roaming in Greece cost for Canadians?

Bell, Rogers and Telus all bill Greece at their international rate. The charge applies on every day your phone uses its Canadian line, even if the only activity was an app syncing in the background.

Carrier and plan	Daily rate in Greece	7 days	10 days	14 days
Bell Roam Better	$16	$112	$160	$224
Rogers (daily roaming)	$18	$126	$180	$252
Telus Easy Roam	$18	$126	$180	$252

Canadian dollars before tax, October 2026 rates, per phone. Bell stops charging after 20 days per line in a billing period, according to its travel page. Rogers also sells International Travel Passes ($45 for 3 days, $75 for 7, $100 for 14, $120 for 30) that work out cheaper than its daily rate on longer trips; see Rogers’ roaming page.

Greece is in the EU, but the EU’s roam like at home rules protect customers of EU and EEA operators, not visitors on Canadian plans. Two people on a ten-day island trip still pay $320 to $360 in daily roaming between them. The Government of Canada’s advice on using mobile devices abroad also warns that background data can set off charges you did not plan for. Our Bell, Rogers and Telus roaming vs eSIM guide has a calculator for your exact dates.

What is the best eSIM for Greece?

A good Greece eSIM uses strong local networks, gives you enough data for maps and bookings and starts counting days only when you land. When you compare options, look at:

• Network access: a plan that can use more than one Greek network gives your phone a fallback on islands where one operator is weaker.
• 5G: helpful in Athens and the busier island towns, where everyone around you is using data at once.
• Validity that starts on arrival: install at home, land at Athens with data ready and lose no days to the flight.
• Hotspot: useful if you carry a laptop or want to share data with a travel partner.
• Plan size: pick by trip length and how much of each day you spend away from Wi-Fi.

Our Greece plans connect to Vodafone and Wind, both with 5G. Your phone joins whichever has the stronger signal where you are. Plans are data-only, so your Canadian number stays on the phone for calls and texts, and the days start when the eSIM first connects in Greece.

The plan page lists every network and shows whether hotspot is included under “Coverage & networks”. If you are not sure your phone supports eSIM, check it with our compatibility checker first.

Telekom, Vodafone or Nova: which Greek network is best?

Greece has three national mobile operators, and two of them have changed names recently:

Operator	What to know
Telekom	The largest operator, part of OTE Group. It was called Cosmote until September 2026, and its network now shows as TELEKOM.GR on phones.
Vodafone	A long-established national network with 5G. Our Greece plans connect to it.
Nova	Formed when Wind Hellas merged into Nova. Our Greece plans connect to the Wind network, which is now part of Nova.

Deutsche Telekom announced the Cosmote to Telekom rebrand in September 2026, including the switch from COSMOTE 5G to Telekom 5G. The Wind and Nova integration followed United Group’s purchase of Wind Hellas in 2022 and was completed in January 2023. You may still see the old names on older blog posts and maps, but the networks themselves have not gone anywhere.

The practical point for travellers is the same as anywhere: having access to two networks beats being locked to one. If Vodafone is weak on a particular beach or hillside village, your phone can try Wind instead. You can see every operator our plans use on our mobile networks page, and our guide to choosing a network for a Europe eSIM explains how multi-network plans work.

Island hopping with an eSIM: what to expect

The biggest advantage of an eSIM in Greece is that one plan covers the whole country. There is no need to find a phone shop on each island, and nothing changes when you step off a ferry in Paros, Naxos or Crete.

Ferries are where data earns its keep. The Government of Canada’s travel advice for Greece says strong winds and bad weather can cause ferry cancellations or long delays, and recommends checking pre-departure notices and reconfirming your schedule before you go to the port. With data on your phone, you can check the operator’s notices from your hotel or a café rather than at a crowded ticket window.

A few island-specific points from the same advice page:

• Carry some cash. ATMs can be scarce or out of cash on small islands and in remote areas.
• Healthcare is more limited on smaller islands. Serious cases may need transfer to a larger hospital, so keep your insurance details on your phone.
• Scooter and quad accidents involving tourists are common, especially on the islands. If you rent one, a phone mount and offline maps help you keep your eyes on the road.

Tip: Before each ferry day, download offline maps for the island you are heading to while you still have Wi-Fi. You will have directions to your accommodation the moment you walk off the boat.

Santorini eSIM: what visitors should know

Santorini is the island most Canadians picture when they plan a Greece trip, and a Santorini eSIM is simply your Greece plan working on the island. You will use it to book transfers from the port or airport, find your hotel among the cliffside lanes, check bus times and reserve dinner with a sunset view.

Santorini is busy in high season, and the places with the best views are often packed at sunset. Having your own data means you do not depend on a crowded café’s Wi-Fi to message friends or upload photos. The Government of Canada also notes that Santorini and Nisyros have active volcanoes, so follow local guidance and keep your phone able to receive alerts.

Across Greece, these emergency numbers are worth saving:

• 112: general emergencies, also used for emergency alerts
• 1571: tourist police, 24 hours a day
• 100: regular police

How much data do you need in Greece?

Many hotels, guesthouses and cafés in Greece offer Wi-Fi, so your mobile data mainly covers time at the beach, on the road and in transit. As a rough guide for one phone:

Type of trip	Typical use	Suggested data
Athens city break, 3 to 5 days	Maps, metro routes, messages, photo sharing	3 GB
One week, Athens plus one island	Ferry checks, maps, social media	3 to 5 GB
Two weeks island hopping	Daily navigation, bookings, uploads, music	8 to 15 GB
Working remotely or sharing a hotspot	Video calls, cloud files, laptop use	20 GB or more

Video uploads and streaming use the most. Set photo backup to Wi-Fi only, and turn off auto-play for videos in social apps. Our guide to how much data you need when travelling shows typical usage by app, and our guide to 5G vs 4G when travelling explains when the faster network matters.

Wildfires, heat and staying informed

Greek summers are hot and dry. The Government of Canada says wildfires are common from July to September, especially in the Peloponnese, central Greece, eastern Macedonia and Thrace, and around Athens, and that smoke can affect air quality near active fires.

This is one of the best reasons to keep data on during a summer trip. Greece uses 112 for emergency alerts as well as calls, and with a working connection you can follow local news, check road closures and contact your accommodation if plans change. Keep your phone charged, and carry a battery pack on long beach or hiking days.

How to set up your Greece eSIM before you fly

Setup takes about five minutes on home Wi-Fi. The plan’s validity only starts when the eSIM first connects in Greece, so installing it days before your flight costs you nothing.

1. Check your phone. It needs eSIM support and must be unlocked. Use our compatibility checker or read how to check if your phone is eSIM compatible.
2. Buy your Greece plan. The QR code arrives by email, usually within about a minute. For a group, you can buy up to 10 eSIMs in one order and send each QR code to its own email address.
3. Install it on Wi-Fi. On iPhone, follow Apple’s eSIM setup guide. On Android, open Settings, go to SIM manager or Network and internet, and add an eSIM by scanning the code.
4. Label your lines. Name the new one “Greece” and your usual one “Canada”.
5. When you land, turn on the Greece line, enable data roaming for it and set it as your mobile data line.
6. Turn data roaming off on your Canadian line so your carrier can’t start a daily charge.

Apple’s guide to using Dual SIM with an eSIM explains how both lines stay active while only one carries data, so texts to your Canadian number still reach you.

For phone-by-phone steps, see our guide to installing an eSIM before you fly. If data does not connect when you land, try our eSIM not working abroad fixes or visit the help centre.

Combining Greece with Italy or other European countries?

Plenty of Canadians pair Greece with Italy, Croatia or a cruise that stops in several countries. Canadians can stay in the Schengen area without a visa for up to 90 days in any 180-day period, and that total is shared across all Schengen countries.

A Greece plan covers Greece only. For a multi-country route, a Europe plan that lists each country is usually simpler. If Italy is on your itinerary, our Italy eSIM guide covers it.

Your next step

Check your phone with our compatibility checker, then compare every Greece eSIM plan by data and validity. Install it at home on Wi-Fi, switch it on when you land in Athens or on the islands, and keep your Canadian line’s data roaming off until you are home.
