Greece travel data eSIM
What is a Greece eSIM?
A Greece eSIM lets you stay online while you explore the ancient streets of Athens, hop between the Cycladic islands, or wander the historic sites of Delphi. With a data‑only plan you can download maps, check ferry schedules, and use translation apps without swapping physical SIMs, keeping your travel experience smooth from the mainland to the islands.
In Greece the eSIM connects to the Wind 5G and Vodafone 5G networks. Your chosen data allowance is drawn down as you browse, stream, or use navigation tools, and the plan remains active for the period specified, whether you are strolling through Thessaloniki or sailing between islands.

Which networks you connect to in Greece
When you activate the eSIM in Greece it links to the Wind 5G and Vodafone 5G operator networks. The actual reach of the connection depends on the specific network you are near, so you’ll be able to access mobile data wherever those operators have infrastructure.

Questions people actually ask
If yours is not here, write to us — we answer within 24 hours.
Which operator(s) does the Greece eSIM use and what does that mean for a traveller?
The eSIM connects to Wind 5G and Vodafone 5G. This gives you access to the same mobile data services those operators provide to local customers while you are in Greece.
Does the eSIM also work in a neighbouring country of Greece?
It is a single‑country plan valid only in Greece. Regional plans are available for travelers who need connectivity in neighboring countries such as Albania or Turkey.
Which plan size suits a trip to Athens and Santorini?
As a rough guide, a 5 GB 30‑day plan often covers moderate usage for two popular destinations, while a 10 GB option provides extra flexibility for streaming and frequent map checks.
Will I lose my own phone number?
No. Your physical SIM stays in the phone and keeps your number for calls and WhatsApp. The eSIM only carries data, so both work side by side.
When does my plan start counting down?
When the eSIM first connects to a network at your destination — not when you buy it. So you can install it days before you fly without losing any time.
Is my phone compatible?
Most phones from 2018 onwards are: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later. Your phone also has to be carrier-unlocked. Dial *#06# — if an EID appears, you have eSIM. Full list on our Device Compatibility page.
How fast will I get my QR code?
Usually within a couple of minutes of payment, by email. If it has not arrived, check spam first, then write to us and we will resend it immediately.
Can I use hotspot or tethering?
Yes, on every plan we sell. Share the connection with a laptop, a tablet or the rest of your group.
What if I change my mind?
If you have not installed the eSIM, you get a full refund within 180 days. Once a profile is activated and data has been used it cannot be refunded — the allowance is consumed from the network. Full detail in our Refund Policy.
Do you sell plans for groups?
Yes. For Umrah and Hajj groups, student trips and tour operators we deliver the QR codes as a single batch before departure, at group rates. Email us with your group size and destination.
