eSIM for Greece in 2026: plans, prices, and coverage on the islands and ferries

Getting data in Greece with an eSIM is straightforward: pick a plan size and validity that matches your trip, install it before you fly, then let it activate when it first connects in Greece. Coverage is generally good around towns and popular beaches, but you should expect dropouts mid-ferry crossing and occasional gaps in mountain villages on Crete and parts of the mainland.

Which eSIM plans and prices to expect for Greece in 2026

For Greece, BeeSim lists 7 fixed-data plans — 1 GB for 7 days, 3 GB, 5 GB, 10 GB, 20 GB, or 50 GB for 30 days, plus 50 GB for 180 days — and 17 daily plans with 500 MB to 10 GB of full-speed data per day for 1 to 30 days.

Concrete examples from the catalog:

• 1 GB / 7 days, see the current plan page
• 5 GB / 30 days, see the current plan page
• 10 GB / 30 days, see the current plan page
• 20 GB / 30 days, see the current plan page
• 1-day plan: 10 GB, see the current plan page

A few practical ways to choose between them:

• Short city break (Athens + one island): a smaller plan with 7 or 30 days is usually enough if you’re mostly on Wi‑Fi at hotels and cafés.
• Island-hopping with maps and bookings, plus occasional uploads: 10–20 GB over 30 days is a common “set and forget” range.
• Remote work or lots of tethering: look for higher data caps and longer validity so you’re not juggling multiple installs.
• Need a lot of data in a single day (arrival day, live-streaming, big uploads): the 1-day 10 GB option exists specifically for that kind of spike.

BeeSim sells data-only eSIM plans for Greece. Calls and SMS still work through apps (WhatsApp, Telegram, FaceTime) over that data, while your physical SIM can stay in your phone for its number.

What coverage is like in Greece (Cosmote, Vodafone, Nova)

In Greece, the relevant mobile networks include Cosmote and Vodafone. Nova is also a local network. Your eSIM will connect through a partner network depending on the plan’s roaming setup.

What that means on the ground:

• Athens and Thessaloniki: typically strong coverage where you’ll be using maps and ride-hailing apps.
• Islands: coverage is generally solid around towns and popular beaches. As you move away from built-up areas, signal can drop.
• Crete and the mainland interior: mountain villages can have gaps. Don’t assume you’ll have data on every road.

Actionable prep if you’re heading off the main roads:

1. In Google Maps (or Apple Maps), download offline maps for:

• Athens (even if you’re just transiting)
• each island you’ll visit
• any driving region on Crete or the mainland

1. Save copies (screenshots or PDFs) of:

• ferry tickets / boarding QR codes
• hotel check-in instructions
• key addresses in Greek and English

1. If you’ll be driving, pre-load your route while on Wi‑Fi so navigation can continue even if data drops.

eSIM coverage on Greek ferries: what works, what doesn’t

On ferries, the rule is simple: near ports and close to shore you often have signal; mid-crossing you may lose it. That’s normal, your phone is still trying to reach land-based towers.

How to avoid being stuck without the things you need mid-crossing:

• Before boarding (on port Wi‑Fi or mobile data):
• open your booking apps once so you’re already signed in
• load your destination in maps
• download entertainment (music/podcasts/videos)
• During the crossing:
• if data stops, don’t keep toggling settings every minute; wait until you’re closer to land again
• switch to airplane mode for a few minutes if your battery is draining from constant network searching, then turn it off when you near the destination

If you absolutely must be online during the entire crossing, you’ll need whatever connectivity the ferry provides (if any). Your mobile eSIM can’t fix the basic “no towers in range” problem.

Greece vs Europe regional eSIMs (and what to do about Cyprus)

Greece is in the EU, so a Europe regional plan covers it. If your trip includes multiple countries, a regional plan can be simpler than buying separate country eSIMs.

Regional bundles that also cover Greece include:

• Balkans (5+ areas)
• Europe (31 areas)
• Europe (33 areas)
• Europe (30+ areas)

One important planning detail: Cyprus is a separate country and needs its own coverage. If your itinerary includes Cyprus (even briefly), confirm your plan explicitly includes it, or buy a Cyprus option.

How to buy, install, and activate a Greece eSIM (without starting the validity early)

With BeeSim, you don’t need an account. You pay by card, Apple Pay, or Google Pay, then install by QR code or in one tap on iPhone; the eSIM opens from the order link.

The key timing detail: the plan’s days start counting when the eSIM first connects at the destination. So you can install days before your trip while you’re still on Wi‑Fi.

A reliable install/activation flow:

1. Check your phone supports eSIM and is unlocked.

• Use the compatibility list: Compatible devices

1. Buy the Greece plan you want: Greece eSIM
2. Install at home on Wi‑Fi (before you travel).

• If you’re on iPhone, use the one-tap install when available.
• Otherwise scan the QR code.

1. Name the eSIM line something obvious (for example, “Greece eSIM”) so you don’t select the wrong line later.
2. Leave the eSIM line turned off (optional but tidy) until you land, or leave it on but keep its data roaming off until arrival.
3. After landing in Greece:

• turn the eSIM line on
• set it as your mobile data line
• turn data roaming ON for the eSIM line

That last step (data roaming) is the one most people miss. Travel eSIMs usually roam onto local networks.

Exact phone settings that fix most “no service” and “no internet” issues

When an eSIM shows bars but no internet, or won’t connect at all, settings are usually the cause. Work through these in order.

How to set the eSIM as the data line (iPhone)

1. Settings → Cellular
2. Tap Cellular Data → select your Greece eSIM
3. Tap your Greece eSIM line → toggle Turn On This Line ON
4. Tap Data Roaming → ON
5. (Optional) Turn Allow Cellular Data Switching OFF to prevent the phone from silently moving data back to your home SIM.

How to set the eSIM as the data SIM (Android)

Menu names vary, but the path is usually:

1. Settings → Network & internet (or Connections)
2. SIMs (or SIM manager)
3. Under Mobile data, choose your Greece eSIM
4. Turn Roaming ON for that eSIM

If data still doesn’t work: quick fixes that actually help

• Toggle Airplane mode ON for 10 seconds, then OFF.
• Restart the phone.
• Manually select a network (useful in ports and island towns where multiple networks are available):
• iPhone: Settings → Cellular → your eSIM → Network Selection → turn off Automatic → try Cosmote, then Vodafone, then Nova.
• Android: Settings → Network & internet → SIMs → your eSIM → Network operators → turn off automatic → try available operators.

If you’re mid-ferry and nothing connects, it may simply be out of range. Wait until you’re closer to land.

Hotspot and multi-device use (and what happens when data runs out)

Hotspot works, so you can share your Greece eSIM data to a laptop or travel companion’s phone.

Two operational details to plan around:

• Plans currently cannot be topped up. When data runs out, you buy a new plan and it installs as a second eSIM.
• If you anticipate heavy tethering, pick a plan with enough headroom so you’re not forced to add another eSIM mid-trip.

If you do end up installing a second plan, keep the older eSIM line turned off to avoid confusion about which line is providing data.

Refund rules to know before you buy

Refund eligibility is simple:

• Any eSIM that has not been installed can be refunded.
• An installed eSIM is refundable only if it never worked.

Also note pricing: prices are charged in US dollars, and the site shows them in your local currency for reference.

FAQ

Will my Greece eSIM work in Santorini, Mykonos, Naxos, or Paros?

In general, yes, coverage on the islands is typically good around towns and popular beaches. Expect weaker signal in more remote stretches and when you’re away from built-up areas.

Does mobile data work on ferries between the islands?

Sometimes near ports and along the coast, but ferries often lose signal mid-crossing. Download what you need before departure and assume you may be offline for part of the trip.

Can I keep my home SIM active for calls and iMessage while using an eSIM for data?

Yes. BeeSim plans are data-only; you can keep your home SIM in the phone for its number and use calling/messaging apps over the eSIM data.

If I run out of data in Greece, can I top up?

No, plans can’t be topped up right now. When you need more data, you install a new plan as a second eSIM.

Should I buy a Greece-only plan or a Europe regional plan?

If you’re only visiting Greece, a country plan is the simplest. If you’re crossing borders, a Europe regional plan covers Greece and can reduce plan switching; Cyprus is separate and needs its own coverage.

When does the plan validity start counting?

The days start when the eSIM first connects at the destination. You can install it in advance on Wi‑Fi without starting the clock.
