Greece travel eSIMs,
compared properly.
Ten local and international options compared by network, local-number access, registration, high-speed data, hotspot use, activation and support.

The short answer
Greece has domestic prepaid and traveller products, but eSIM availability can differ between the named tariff and the issue channel. Vodafone CU clearly publishes eSIM activation, while COSMOTE's traveller offer should be checked for the exact SIM format.
Choose a confirmed domestic eSIM when a Greek number matters. Use a global data profile if you want installation before flying and do not want to depend on a local shop.
Do not assume that a product called a traveller SIM is automatically available as eSIM. Confirm the format, island coverage, EU roaming and hotspot rule before paying.
Prices are deliberately excluded because promotions move quickly. Product characteristics and official local guidance were checked on 24 August 2026; the linked checkout terms take precedence if they change.
Compare the same allowance, validity and named network across global providers.
Read fair-use and hotspot definitions before buying an unlimited-labelled plan.

Provider directory
Ten Greece eSIM options.
These services are grouped by model, not ranked. Compare the final checkout for the same high-speed data, trip length, local-number need and hotspot behaviour.
| Provider | Model | Published plan shape | Number / calls | Hotspot | Useful for | Verify before paying |
|---|---|---|---|---|---|---|
| Vodafone CU eSIM↗ | Local operator or domestic prepaid route | Vodafone CU publishes QR-based eSIM activation for its prepaid service. | A Greek Vodafone number with calls, SMS and data according to the selected CU package. | Check tethering, speed management and any fair-use limit on the exact plan before relying on it for laptop work. | Visitors who can complete the local activation process and want a Greek number. | Confirm passport registration, the actual prepaid package, EU roaming and whether activation must occur in a shop. |
| COSMOTE Traveller's SIM↗ | Local operator or domestic prepaid route | COSMOTE advertises a traveller-specific local SIM with data. Treat it as a physical fallback unless the exact checkout expressly offers eSIM. | A Greek mobile number on the registered local traveller product. | Check tethering, speed management and any fair-use limit on the exact plan before relying on it for laptop work. | Direct COSMOTE network testing and local support. | Confirm the current SIM format, allowance, validity and registration channel before purchase. |
| Airalo↗ | Global eSIM marketplace and app | Greece-only packages may sit beside regional and global products. Fixed-data, validity and unlimited-labelled choices can have different technical terms. | Usually data-only. Treat any voice or SMS inclusion as a feature of the exact package, not the brand generally. | Confirm the sharing rule on the selected package. | Comparing country, regional and global choices in one account. | Open the network, activation policy, voice, SMS, speed and identity fields for the exact package before checkout. |
| Nomad↗ | Global app-based travel eSIM provider | The Greece page may publish fixed allowances and unlimited-labelled daily products. Partner networks and daily high-speed definitions can vary by plan. | Primarily mobile data rather than a domestic mobile number. | Check the chosen fixed or daily product and its current fair-use wording. | Comparing several allowances and, where disclosed, more than one partner network. | Confirm the high-speed amount, reduced speed, reset period, activation deadline and refund rule. |
| Saily↗ | Global reusable travel eSIM app | Country-specific and regional data packages are sold through one reusable profile. Check the current Greece page for allowance and validity. | Data-only unless the checkout expressly adds a separate number product. That would not normally be a local number. | Check the sharing rule, especially on an unlimited-labelled option. | App-based top-ups, usage controls and keeping one profile for later trips. | Confirm when validity starts and whether security add-ons or virtual location features affect the intended use. |
| Holafly↗ | Global duration-based travel eSIM provider | Unlimited-labelled Greece data may be sold by trip length, subject to fair-use and network-management wording. | Usually data-only. Internet calling does not create a domestic mobile number. | Sharing limits can be materially lower than phone-data limits. Check the country page before paying. | Heavy phone-data use when buying by number of days is easier than estimating a fixed allowance. | Read the fair-use, reduced-speed and hotspot clauses. Unlimited does not mean unlimited full-speed laptop use. |
| Jetpac↗ | Global reusable travel eSIM provider | Fixed-data and unlimited-labelled choices may be available for Greece; the selected product defines the daily high-speed amount. | Data-only; optional in-app calling does not provide a domestic SIM number. | The provider generally publishes tethering, but the selected package still controls. | Travellers who value explicit plan definitions and a reusable profile. | Check the activation window, current partner network, daily reset and the value of ancillary travel benefits separately. |
| Ubigi↗ | Global reusable data eSIM provider | One-off and recurring data choices may be available. The current Greece product page controls the network and allowance. | Data-only service. | Verify data sharing on the selected plan and device. | Repeat trips, app-based top-ups and comparing one-off service with a recurring bridge. | Recurring options may have a minimum period. Check cancellation, reinstallation and fair-use terms before subscribing. |
| GigSky↗ | Global travel eSIM provider | Fixed-data and unlimited-labelled products may be offered through a reusable app profile for Greece. | Data-only; standard mobile voice calls and SMS are not included. | Check hotspot support and any daily high-speed threshold on the chosen plan. | People who also need regional, global, cruise or inflight products within one service. | The local network can vary. Confirm the present partner network, daily allowance and renewal rule. |
| Orange Travel↗ | Operator-owned global travel eSIM service | Search for Greece in Orange Travel and compare the country product with any regional option. Packages can include data-only or voice-enabled service. | Varies by package. Confirm whether a number is included and which country issued it. | Check the exact destination plan and fair-use wording. | Travellers who prefer an established mobile-operator group and in-app management. | Orange Travel is separate from a domestic Orange subscription. Confirm the named network, number, validity and refund rule. |
Comparison note: a domestic operator eSIM and an international roaming eSIM can use the same radio network while providing different numbers, routing, priority, support, registration, reinstallation and fair-use terms.
The network underneath
A provider name is not coverage.
COSMOTE, Vodafone and Nova are the main networks. Island, ferry, mountain and rural coverage can vary far more than central Athens service.
Test the possible home, urban commute, ferry route and the specific island or rural area relevant to the planned life.
Start with the provider's exact network field, then compare it with the current official sources below. A coverage map is a prediction and cannot guarantee signal inside a future home.
Routing matters too.An international eSIM may send traffic through an overseas gateway. That can affect latency, IP-based services and where an app thinks you are even when the local radio signal is strong.
Scouting-trip use
Use data to investigate a life, not merely navigate a holiday.
Save possible homes, test peak-hour routes, message agents, translate administrative conversations, locate clinics and run a real work call away from hotel Wi-Fi. Test the possible home, urban commute, ferry route and the specific island or rural area relevant to the planned life.
Arrival sequence
Configure the two lines deliberately.
Menu names vary. Use the phone manufacturer's current instructions plus the purchased provider's destination setup guide.
- 01
Confirm compatibility and unlock status
Match the exact phone model and market variant. eSIM support does not prove that the device is unlocked or compatible with local voice requirements.
- 02
Install over reliable Wi-Fi
Save the QR code, manual activation details, receipt, terms and support contact offline. Check whether installation starts validity.
- 03
Label the lines
Name them “Home” and “Greece data”. Select the travel eSIM for mobile data and disable automatic data switching.
- 04
Follow roaming and APN instructions
Enable data roaming only on the travel line when required. Keep home-line data roaming off unless deliberately needed.
- 05
Complete local registration
A domestic prepaid line is identity-registered. Bring a passport and confirm whether the selected provider supports visitor self-registration or requires a shop.
- 06
Test before leaving the gateway
Turn off Wi-Fi at Athens International Airport, load a map and webpage, then check the selected data line. Keep a fallback and do not delete the eSIM unless support confirms it can be reinstalled.
If Greece becomes home
Travel data is a bridge. A domestic mobile arrangement is a separate decision.
A Greek number can become important for utilities and local accounts. Compare operator and MVNO plans only after checking tax-number, address and payment requirements.
Keep the travel eSIM working until the new line has been activated, tested and attached to the accounts that matter. Do not cancel the home number before changing every recovery and verification method tied to it.

Greece eSIM questions.
Where an answer depends on a plan, the provider's current product terms take precedence over this overview.
Which is the best eSIM for Greece?
There is no supportable winner for every trip. Start with the need for a Greece number, then compare the exact local network, high-speed allowance, hotspot rule, validity and support. Choose a confirmed domestic eSIM when a Greek number matters. Use a global data profile if you want installation before flying and do not want to depend on a local shop.
Do I need a passport for a Greece eSIM?
A domestic prepaid line is identity-registered. Bring a passport and confirm whether the selected provider supports visitor self-registration or requires a shop. A global data-only travel eSIM follows the seller's identity process instead and may not provide a domestic number.
Should I install my Greece eSIM before flying?
Install a global travel eSIM while reliable Wi-Fi and support are available, unless the provider says installation starts validity. A local product may require arrival, identity verification or an in-country network connection. Save the QR code and manual settings offline.
Will a data-only eSIM work for a relocation-scouting trip in Greece?
It will support maps, web access, translation and app messaging. A Greek number can help with agents, accommodation callbacks, deliveries and domestic account verification. Data-only service covers maps, ferry information and messaging. Keep the home number available for account recovery and check whether receiving an SMS while roaming costs anything.
Does an unlimited Greece eSIM provide unlimited hotspot use?
Not necessarily. Find the full-speed amount, reduced speed, reset time, traffic-management terms and separate tethering limit. Compare usable high-speed data rather than the word unlimited.
Can one eSIM cover all of Greece?
Only where the selected partner network and local conditions provide service. COSMOTE, Vodafone and Nova are the main networks. Island, ferry, mountain and rural coverage can vary far more than central Athens service. Coverage maps are useful predictions, not guarantees inside a specific building or along every route.
