Unlimited data eSIM for Greece: what "unlimited" really means and what it costs

Search "unlimited eSIM Greece" and almost every brand says unlimited. Read the small print and many of them mean a high-speed allowance per day, then a slow connection until midnight. That matters in Athens when you are uploading photos, and on Santorini when you are navigating ferries and bookings.

This page explains the difference in plain terms, shows exactly what VoaSim charges for Greece, and gives you a short checklist to test any brand's terms before you pay.

What "truly unlimited" means on a VoaSim eSIM for Greece

With VoaSim there is no data cap, no speed throttling and no hidden fair-use policy. Day 1 and day 14 behave the same way. You stream, map, upload and video call for as long as the plan lasts.

Two details to know before you buy. It is a data-only eSIM: you get no new phone number and no traditional voice calls, but WhatsApp, FaceTime, Google Maps and everything else over data work normally. And hotspot/tethering is not allowed — if you share the connection, the local carrier may block the line. Travelling as a couple or family? Buy one eSIM per traveler; a second eSIM in the same order gets 10% extra off.

Your physical SIM stays in the phone, so your usual number keeps receiving WhatsApp messages. Just turn off data roaming on your home carrier so nothing is billed by accident. More detail on how it works on the eSIM page.

Prices for Greece by trip length

VoaSim sets the price by destination and trip length, so Greece has its own prices. Prices below already include today's 15% promo.

Trips of 1 to 4 days pay the 5-day package. Maximum is 90 days per eSIM. Payment is by international credit or debit card in USD through Stripe, with an invoice by email and no hidden fees. Get your exact price in the price simulator.

How other "unlimited" eSIMs for Greece are written

Fair comparison, no prices here — check each brand's own site for current rates.

• Airalo: unlimited plans come with a daily high-speed allowance by default (it can vary by package), then roughly 1 Mbps for the rest of the 24 hours; tethering counts toward the same allowance.
• Holafly: no published daily cap, but its terms say operators may reduce speed under fair use for up to one day, and hotspot is limited per day.
• Nomad: unlimited plans include a daily high-speed allowance on most packages, then about 1-2 Mbps. Nomad states openly that these plans do not offer unrestricted high-speed data.

Other brands — Saily, Ubigi, Maya, Yesim, GigSky, Alosim, Jetpac, Instabridge, Roamless — sell by GB or by day, usually in-app. None of this is bad; if you only check email in Athens, a small by-the-GB plan can be cheaper. We publish a daily comparison that separates plans with and without a daily high-speed cap in the eSIM Price Index.

Checklist: how to read any eSIM's terms before you pay

Five questions answer almost everything. Ask them on any brand's site, including ours.

1. Is there a daily high-speed allowance? If the page mentions GB per day with reduced speed afterwards, it is capped unlimited, not unlimited.
2. Is there a fair-use clause? Look for "may reduce speed" or "under fair use". That is where throttling lives.
3. Is hotspot allowed, and is it limited? Some brands cap it; VoaSim does not allow it at all.
4. When do the days start? On VoaSim, counting starts at the eSIM's first connection to a network in Greece — not at purchase.
5. What happens if it does not connect? VoaSim refunds 100% if support cannot get you online.

Coverage in Greece: Athens, the islands and the ferries

The eSIM connects automatically to local Greek networks — Cosmote, Vodafone and Nova — on 4G and, where available, 5G. There is nothing to configure: no APN, no network list, no shop visit.

In practice, Athens, Thessaloniki and the bigger islands (Crete, Rhodes, Santorini, Mykonos, Corfu) have solid urban coverage. Away from villages, in mountain roads and on small beaches, signal depends on the local network, exactly as it would for a Greek SIM.

On ferry crossings the signal comes and goes once you are in open water; the same applies to cruises, where the eSIM works on land at ports but not at sea. Download your ferry tickets, boarding passes and offline maps before you sail.

Install before you fly: the five-minute routine

After payment, the QR code arrives by email within minutes (plus a WhatsApp heads-up if you left a number). Install it at home, on Wi-Fi, while you still have time and patience.

1. Check compatibility: iPhone XR or newer, Galaxy S20 or newer, Pixel 3 or newer, and most phones from 2020 on. Universal test: dial *#06# — if an EID appears, your phone supports eSIM. Carrier-locked phones must be unlocked first.
2. Scan the QR code and add the eSIM line, but keep that line switched off. On Android, do not switch on the eSIM's data before the trip.
3. Land in Greece, turn the eSIM line on, set it as your data line and turn off data roaming on your home carrier.

If anything looks wrong on arrival, the free eSIM Rescue tool diagnoses an eSIM of any brand with no signal, and human support answers at hola@voasim.com or on chat.
