Will I have signal on the caldera and on ferries between islands?

Coverage is good across the caldera villages and most beaches. On ferries you'll usually keep a signal near the coast and between close islands, but expect it to drop in open water, so download tickets and maps beforehand.

Is the same plan valid if I island-hop from Santorini?

Yes. It's a single national Greece plan, so the same eSIM keeps working if you ferry on to Ios, Naxos or Mykonos, or fly back to Athens - no need to buy a new SIM for each island.

Good to know in Santorini

Santorini's ferries run from Athinios port, not Fira - roads there are steep and winding, so keep your eSIM live to track your transfer, confirm the ferry gate and re-check departures, which shift with the wind.

Two simple ways to buy

Santorini eSIM plans: unlimited, or by the GB.

Every Santorini eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Santorini — you can always top up or switch on your next trip.

Traveller streaming and browsing freely on an unlimited-data travel eSIM

Unlimited plans

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

Best for streaming, video calls & hotspot
Great for longer or open-ended trips
One price per day — no GB anxiety

By-the-GB plans

3GB10GB20GB

A set bundle, brilliant value

A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.

Plan your data

How much data do you need in Santorini?

A rough, honest guide to sizing your Santorini eSIM so you're not guessing. Most travellers in Santorini are comfortable on 3–5 GB a week — heavy streamers just go Unlimited.

Santorini eSIM: your local data guide.

Santorini's cliffside villages don't make navigation easy, so live data matters: you'll lean on it to time the Oia sunset before the crowds swell, book a caldera catamaran cruise, and find your way down Fira's stepped lanes. A Santorini eSIM keeps maps, restaurant bookings and photo uploads flowing whether you're in Imerovigli or on Perissa's black-sand beach.

One eSIM for Santorini and all of Greece. It's the national Greece eSIM — from $2.15/day with unlimited data, working the same in Santorini as it does the moment you leave it.

Landing at Santorini (Thira) National Airport (JTR)?

Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.

On the ground

Where you'll lean on data in Santorini.

Oia

Reliable data helps you reserve a sunset dinner table and geotag those blue-domed church photos before the evening rush.

Fira

Use maps and ride apps to navigate the capital's cliff paths, cable car and the bus links to the beaches.

Imerovigli

Stream music on the quieter caldera walk to Skaros Rock and share the view straight to your feed.

Akrotiri & Perissa

Pull up opening times for the ancient Akrotiri site, then check bus schedules back from the black-sand beaches.

The practical bit

Getting around Santorini on your eSIM.

Apps you'll want online in Santorini

Ferryhopper— Books and stores your ferry tickets to Athens, Crete and nearby isles; syncs over data.
Welcome Pickups— Pre-books airport and port transfers with flight tracking; the app updates your driver over data.
Google Maps— Guides you along narrow caldera roads and to the Fira bus hub; data keeps it live.

How long to stay in Santorini

Santorini is usually a two to three day stop, long enough for sunset in Oia, a caldera boat trip to the volcano, and an evening wandering Fira.

How much data for Santorini

Santorini is all about sharing sunsets, so photo and video uploads dominate; 3-5 GB suits a couple of days, but choose Unlimited if you plan to stream, video-call home or post reels every evening.

Coverage in Santorini

Signal is strong across Fira, Oia and the caldera-edge villages, but it genuinely thins on the remote southern beaches, along the Fira-to-Oia clifftop hike, and out on the volcano boat trips.

Peace of mind

Your Santorini eSIM: data-only, zero bill shock.

Your Santorini eSIM handles the internet while you travel. Your home number stays exactly where it is — no surprise roaming charges in Santorini, no swapping your real SIM out.

Keep your number & WhatsApp

The eSIM is data-only and runs alongside your home SIM. Your number, iMessage and WhatsApp keep working exactly as they do at home.

No roaming bills, ever

Turn data roaming OFF on your home SIM and ON for the eSIM. You pay once, up front — no overage, no metered surprises, no bill waiting when you land home.

One thing worth knowing

Because it's data-only, the eSIM can't receive bank verification (OTP) text codes — those still go to your home number. Keep it reachable on Wi-Fi calling, or use app-based codes.
