Greece is the ultimate dream destination – ancient ruins in Athens, the white villages of Santorini, beaches on Crete, parties on Mykonos and hidden coves on Corfu. But how do you stay online on the Greek islands? An eSIM is the simplest solution – especially if you're traveling from Switzerland or a non-EU country.
Why use an eSIM for Greece?
While Greece is an EU member, if you're traveling from Switzerland, EU roaming rules don't apply to you. Swiss carriers charge Greece roaming separately. An eSIM is cheaper and gives you full cost control.
Benefits of an eSIM for Greece:
- Cheaper than Swiss roaming – fixed price instead of expensive roaming surcharges
- Instant connection – install at home, activate on arrival
- Works on all islands – good 4G coverage even on smaller islands
- Dual-SIM – keep your home number active
- No SIM hunting – no searching for phone shops on the island
- Perfect for island hopping – one eSIM works across all Greek islands
Available eSIM packages for Greece
- 1 GB / 7 days – for a weekend in Athens or on an island
- 3 GB / 15 days – perfect for a week's island holiday
- 5–10 GB / 30 days – for 2 weeks with social media and video calls
- Unlimited / 7–30 days – worry-free surfing, ideal for island hopping

Good coverage: Most inhabited islands have 4G – Crete, Rhodes, Corfu, Kos, Zakynthos, Kefalonia, Paros, Naxos, Lefkada

Island hopping with eSIM
Greece is famous for island hopping – and an eSIM makes it even easier. A single package works on all Greek islands. When changing ferries, you don't need to adjust anything – the eSIM automatically connects to the nearest network.
Popular island hopping routes:
- Cyclades route: Athens → Mykonos → Paros → Naxos → Santorini
- Dodecanese route: Athens → Rhodes → Kos → Symi
- Ionian Islands: Corfu → Lefkada → Kefalonia → Zakynthos
Tip: For 2+ weeks of island hopping, we recommend an unlimited package or at least 10 GB.
Combining Greece & the Balkans
Many travelers combine Greece with Albania (just a few hours from Corfu) or other Balkan countries. For such trips, consider a Balkans regional package or a Europe package.
Tips for mobile internet in Greece
- Offline Google Maps – download maps for your islands, especially for scooter tours
- Ferry apps – Ferryhopper or Greek Ferries need internet for bookings and live tracking
- Beach spots – even at remote beaches you usually have 4G signal
- Share hotspot – most packages allow tethering for travel companions
- Check regional packages – if you're also visiting Albania, Turkey or neighboring countries
