Our Method
Greece eSIM scoring, category by category
We score five eSIM providers for Greece, all of which sell plans on Cosmote (OTE)'s 5G network. Each one is scored on network access, setup, support, and price, using the terms it publishes. Greece presents a 4G-dominant connectivity environment, so the carrier a provider routes through matters more here than the brand on the checkout page.
Methodology
How this Greece guide is built
Where the data comes from
This guide covers 5 eSIM providers that sell plans for Greece. Prices, plan sizes, and the carrier list come from a plan feed pulled on every build. Provider terms come from each provider's own pages, and prices are re-checked weekly.
What we do not publish
We run no speed tests, so this page has no Mbps figure for any provider in Greece. We do not time support desks either, so no reply window appears here. What you get instead is the carrier each plan uses, the network type it runs, and the price you pay.
Network Data
What Cosmote (OTE) gives you in Greece
Greece runs 2 carrier networks in our plan feed, and 5G is the top network type across them. Cosmote (OTE) is the carrier most travel eSIM plans use here.

Operator Data
Operators carrying your eSIM: Greece
One network or several changes what happens when the signal drops. Here is the list, straight from the source.
HelloRoam publishes two local operators for Greece: Vodafone or Wind. Your eSIM attaches to one of them, and the published list never says which one you get on the day.
HelloRoam labels every one of them 5G in Greece. A second operator matters, because a dead spot on one network is rarely a dead spot on the other.
| Local operator | Network listed |
|---|---|
| Vodafone | 5G |

QR Code Scan to First Connection
HelloRoam sends the QR code by email right after payment. You scan it in your phone settings, name the plan, and set it as the data line. The profile then attaches to Cosmote (OTE)'s network when you land. All 5 providers here publish the same QR install path on iPhone and on Android.

HelloRoam is the best eSIM for Greece, routing plans through Cosmote (OTE), the widest Tier-1 host in the country, at $0.89/GB on 5G. Greece eSIM at $0.89/GB is mid-range for Europe — local SIMs cheaper but require mainland purchase. HelloRoam remains the first pick for Greece. Airalo is the multi-country alternative: it sells Greece plans through both Cosmote (OTE) and Vodafone GR, which helps when Cosmote (OTE) coverage thins in rural areas. HelloRoam includes hotspot and tethering on every Greece plan. Holafly is the unlimited-data alternative, from $3.10/day, for travelers who stream or take video calls and do not want a fixed cap. HelloRoam is the overall pick on score, support, and refund window. Cosmote tourist SIM at €10 for 10GB covers most island trips; cheaper than roaming from other EU countries.
Data Tips
Greece data usage tips, trip by trip
Travelers to Greece consume an average of 1.5GB per day based on regional usage data. A standard two-week trip therefore requires roughly 21GB — plan your tier accordingly. WiFi is widely available in Greece's urban centres and tourist areas, letting you offset mobile data consumption at restaurants and accommodation. Free WiFi in most cafes and tavernas; hotel WiFi generally reliable Peak travel season in Greece runs Jun-Sep. Summer peak for islands; Athens best in spring/fall; shoulder seasons offer better value Network congestion during peak periods can reduce effective speeds in high-traffic tourist zones — consider buying one tier higher than your estimated daily usage. HelloRoam's Greece plans start at $0.89/GB with full-speed data on all tiers. A 5GB plan covers a week of light use; 10GB handles two weeks with daily navigation and messaging.
Verdict
Greece: our verdict
HelloRoam is the best eSIM for Greece in 2026 for most travelers. The combination of competitive pricing at $0.89/GB, Cosmote (OTE) carrier access, and 5G network types makes it the clear winner on our rubric.
Choose Airalo if you are visiting Greece as part of a multi-country trip. Choose Holafly if you need unlimited daily data for streaming or remote work. Choose Saily if privacy and VPN protection are priorities.
Arrival
Greece arrival with the eSIM already installed
Install the profile before you fly, then turn airplane mode off after landing at Athens (ATH) / Heraklion (HER) / Thessaloniki (SKG) and the eSIM attaches to Cosmote (OTE). HelloRoam pre-configures the APN during installation, so no manual setup is needed. Some providers ask you to pick the network by hand on Android. Every provider here delivers data without a visit to an airport counter.
Networks
Greece carrier network analysis
Greece's mobile infrastructure runs on Cosmote (OTE), Vodafone GR, and Wind Hellas, with 5G as the top network type in our plan feed. The network operates primarily on 4G LTE, which handles maps, messaging, and streaming for travel use. Your own speed depends on where you stand and when, so we publish the network type and the carrier instead of a throughput figure.
Network Type
What 5G Means for Your Trip to Greece
A 5G connection on Cosmote (OTE) in Greece covers what travelers actually do: video calls, maps, messaging, social media, and streaming. A travel eSIM on Cosmote (OTE) rides the same towers as a local SIM on Cosmote (OTE), so neither format has a network advantage over the other.
Southern Europe
Southern Europe Connectivity: Greece in Context
Southern European destinations attract massive tourist volumes that strain mobile networks during peak season. Beach resorts, historic city centers, and popular islands in Greece experience network congestion from June through September. Cosmote (OTE)'s network handles the load but speeds drop 15-25% in the most visited areas during peak hours.
Coastal and island coverage in Greece is generally good at established resort areas. Smaller islands and remote beaches may have weaker signal. Cosmote (OTE)'s tower density along popular coastlines is sufficient for navigation, messaging, and social media. Streaming quality depends on proximity to the nearest tower.
Rural Coverage
Greece coverage beyond the big cities
Cosmote (OTE) provides the widest rural coverage in Greece. Rural areas have adequate but slower coverage. Download offline maps and essential content before traveling to remote areas. A travel eSIM rides whichever carrier its provider has an agreement with, and no carrier in Greece eliminates every rural dead zone.
eSIM vs Local SIM
Greece local SIM card against an eSIM
Local prepaid SIMs in Greece cost $8-15 for 5-15GB / 28 days and are available at the airport. A travel eSIM at $0.89/GB removes the queue, passport requirement, and SIM swap. Greece requires SIM registration, adding friction to the local purchase process. For trips under two weeks, a travel eSIM is the more practical choice.
Timing
Tourist Season Impact on Greece Connectivity
Network performance in Greece varies by season. During Jun-Sep, tourist-heavy areas carry more traffic on the same towers, so data slows in the busiest zones. Buy one data tier above your estimate for a peak-season trip. Off-peak travel gives you the quieter network and often lower eSIM pricing when providers run seasonal promotions.
Common Questions
What Travelers Ask About Greece eSIMs
What is the best Greece eSIM?
The best eSIM for Greece is HelloRoam (8.9/10), offering plans from $0.89/GB on Cosmote's 5G network. Airalo (8.7/10) covers Greece with regional bundles for multi-country itineraries. Holafly (8.3/10) offers unlimited daily data from $2.50/day.
What separates a Greece eSIM from a SIM card?

Travel eSIMs from HelloRoam ($0.89/GB) and Airalo ($1.70/GB) connect to Cosmote's 5G network with no registration needed. Note: Greek island ferry routes may have limited offshore signal.

Your eSIM in Greece runs at whatever Cosmote delivers where you are standing, on its 5G network. Vodafone Greece is the other carrier in our plan feed. HelloRoam connects to Cosmote, a Tier-1 host. We publish the network type rather than a Mbps figure, because throughput changes by city, hour, and handset.
What are the steps to set up a Greece eSIM?
To set up an eSIM for Greece: buy a plan from HelloRoam or Airalo, scan the QR code in your phone's settings (Settings > Cellular > Add eSIM on iPhone), and activate the plan before departure. The eSIM connects to Cosmote's 5G network automatically when you arrive. Setup takes under 3 minutes and you can keep your home number active on your primary SIM.
What Fell Short
Greece issues we found
Rural and remote areas have coverage gaps on all carriers. No eSIM provider offers local phone numbers for Greece plans.

Your phone connects through Cosmote (OTE) and Vodafone GR, delivering 5G coverage. Carrier-locked phones from AT&T, Verizon, or T-Mobile may need unlocking before use. All five providers we review — HelloRoam, Airalo, Holafly, Saily, and Nomad — support the same device list.
04What does an airport SIM counter add over a Greece eSIM?
A travel eSIM at $0.89/GB competes directly with airport SIMs in Greece. Local airport plans from Cosmote and Vodafone and Wind typically cost $10-20 for 10-20GB / 28 days. The eSIM removes the kiosk queue, passport registration requirement, and SIM swap process — the plan installs before departure and activates on landing. Local airport SIMs can undercut eSIM pricing in some tiers but require in-person purchase and, in some cases, ID registration.
05What happens when a Greece eSIM runs beside your regular SIM?
Yes. Most modern phones support dual SIM operation with one physical SIM and one eSIM active simultaneously in Greece. Your home SIM keeps your regular phone number for calls and texts. The travel eSIM handles data locally. Switch the default data line in your phone settings without removing your home SIM.
06What activation time does a Greece eSIM take?
Activating a travel eSIM for Greece takes under 90 seconds from purchase with most providers. You receive a QR code by email within 60 seconds of payment. Scan it in your phone’s cellular settings, label the plan, and set it as your data line when you land in Greece. Installation can happen before departure so the plan is ready the moment you arrive.
07What happens when Greece eSIM data runs out?
HelloRoam and Airalo both support in-app top-ups that activate within minutes if you exhaust your plan in Greece. Purchase additional data through the provider’s app without buying a new eSIM or swapping a SIM card. Alternatively, purchase and install a second eSIM plan alongside the first. Holafly unlimited plans renew each day automatically.
08Is it eSIM, e-SIM, or e SIM?
eSIM, e-SIM, and e SIM all refer to the same technology — an embedded SIM built into your phone. The official industry term is eSIM (embedded SIM), standardized by the GSMA. Whether you search for e-SIM or e SIM, you will find the same digital SIM card technology. No physical card needed.
