What to check before buying a travel eSIM

- Carrier unlock status: phones bought on instalment plans may be locked to your home carrier. Most outright purchases are unlocked.
- iOS version: iOS 12.1 or newer for full eSIM support.
- Android version: Android 9 or newer typically supports eSIM, though it depends on the manufacturer.
- Region-specific variants: some Samsung models sold in Hong Kong or China are dual physical SIM with no eSIM , verify your specific model number.

Tip: if your current phone doesn't support eSIM but you travel often, an unlocked, mid-range eSIM-capable phone (e.g., Pixel 7a, iPhone SE 3, Samsung Galaxy A55) makes an excellent secondary travel device , pair it with a Cellesim plan and you have a full mobile internet kit for any destination.
No! This is the #1 roaming trap.
- For UK Travelers (Post-Brexit): Most UK carriers have reintroduced daily roaming fees (e.g., £2-£6 per day) for Greece.
- For US/Canadian Travelers: Your home carrier (like AT&T or Verizon) will charge an expensive "Day Pass" (e.g., $10-$14 per day).
A Cellesim eSIM is a one-time prepaid fee that is significantly cheaper than paying these high daily charges.
Yes, absolutely. Our eSIM plan covers all the Greek islands, not just the mainland. You will have a strong 4G/5G signal in Athens, Thessaloniki, and on all major islands like Crete, Rhodes, Corfu, Mykonos, and Santorini.
Yes, for most of the journey. The ferry routes between the main islands (Piraeus -> Mykonos -> Santorini) are very busy and have excellent 4G coverage. While you may briefly lose signal in the deepest open water, you will be connected for 95% of your trip, allowing you to stream or browse while sailing.
This specific plan is valid only within Greece (and the EU). This is a critical point. If you are on a cruise that stops in Kuşadası (Turkey) or take a ferry from Corfu to Albania, your connection will stop as they are not in the EU. For this, we highly recommend our Europe Regional eSIM, which covers both Greece and Turkey.
Yes, 100%. Buying a physical "Tourist SIM" at Athens Airport (from Vodafone, Cosmote, etc.) requires waiting in long queues (especially after a big flight lands) and going through a mandatory passport registration process as required by EU law. Our eSIM is 100% digital, requires no ID registration, and can be installed before you fly, so you are connected the moment you land.
To give you the best speed and coverage, our eSIM connects to Greece’s premium Tier-1 networks, typically Cosmote or Vodafone Greece. Cosmote is widely regarded as the #1 provider with the fastest speeds and the most extensive 5G/LTE coverage, especially on the islands.
Yes. Wi-Fi in many "cave" hotels and Airbnbs in Oia (Santorini) or Mykonos Town is notoriously slow, congested, and shared with all guests. A personal eSIM gives you a private, fast 4G/5G connection that works in your room, by the pool, and, most importantly, on the beach, where hotel Wi-Fi never reaches.
Most modern phones do, but you must check our specific list here: eSIM Compatible Devices to be 100% sure before purchasing.
Yes. Free Now is the most popular taxi app in Greece (Uber is limited to taxis), and reliable data is essential to book rides in Athens or Thessaloniki.
Yes. Coverage is generally strong near the cliff-top monasteries of Meteora, allowing you to upload photos of the "floating rocks" instantly.
