Greece is one of the most popular holiday spots: Crete, Rhodes, Corfu, Santorini, Zakynthos — the list is long. Because Greece is an EU member state, the 'Roam Like at Home' rules apply, so in theory you can browse with your home plan without any problem. But is that really always the best solution?
EU Roam Like at Home: the basics
Since 2017, roaming has been free within the EU: you can use your home plan's data allowance in Greece too, at domestic rates. For a short, 1–2 week holiday this is usually perfect.
But there are a few important limits:
- Fair Use Policy (FUP): The carrier can cap the amount of data you use abroad. With unlimited plans this can be as little as 10–15 GB/month.
- 90-day rule: If you spend more time abroad than at home over a four-month period, the carrier can add a surcharge.
- Speed: While roaming, the local network may give priority to its own subscribers.
When is an eSIM better even within the EU?
| Situation | EU roaming | eSIM |
|---|---|---|
| Short holiday (1–2 weeks) | Perfect | Not needed |
| Long stay (30+ days) | FUP limit can be a problem | Better choice |
| Digital nomad work | 90-day rule is problematic | Ideal |
| High data need (3–5 GB+/day) | FUP cap | Larger allowance |
| Remote islands, weak signal | Roaming network can be slower | Local network priority |
Greek mobile networks
There are three main operators in Greece:
- Cosmote — the widest coverage, available on most islands
- Vodafone Greece — reliable, good urban coverage
- Wind Hellas — more affordable, good on the mainland, weaker on smaller islands
eSIM Surfer plans connect to these local networks, so you get the best possible coverage.
Coverage on the Greek islands
- Big tourist islands (Crete, Rhodes, Corfu, Santorini, Mykonos, Zakynthos): reliable 4G/LTE
- Medium islands (Paros, Naxos, Kefalonia, Lefkada): generally good, but weaker in mountainous interiors
- Small islands (Lesser Cyclades, remote Dodecanese): 3G/4G, in places only 2G or no signal
- Ferries: on the major ferry routes (e.g. Piraeus–Crete) there's usually a signal, but it's patchy on open water
Island to island: ferries and coverage
If you're island hopping, internet is especially important for timetables, bookings and maps. Tips:
- Download offline Google Maps for every island you visit
- Book ferry tickets in advance through the Ferryhopper or DirectFerries app — there isn't always a good signal at the port
- On the ferries the signal varies — download everything you'll need before you board
Practical tips
- Check your FUP limit before you travel: call your carrier or check their app
- If you stay more than 3 weeks, it's worth switching to an eSIM for internet — that way you don't hit the FUP cap
- Cyprus is also an EU member state, so if you continue your trip from there, roaming applies just the same
Summary
For a short holiday in Greece, EU roaming is perfect. But if you're planning a longer stay, need a lot of data, or are heading to remote islands — an eSIM is the safer choice. Greece plans in the eSIM Surfer app start from €1.99 for 1 GB/7 days, with 10 GB/30 days at €8.99, and you can buy in minutes in your own currency.
