Among the verified fixed-data EUR offers in this comparison, PikoeSIM costs less than Nomad on each exact match available: 1 GB for seven days and 5, 10, 20 or 50 GB for 30 days. That is a comparison of these observed offers, not proof of the cheapest eSIM in the entire market. Trip duration, activation terms and existing roaming can still change the right choice. [1] [2]

Disclosure: this comparison was commissioned by PikoeSIM's operator. Prices are published offers checked on 28 October 2026; no purchase or independent network-speed test was performed.

Compare the same allowance for the same period

A five-gigabyte plan lasting ten days is not equivalent to one lasting thirty. The shorter plan can be excellent for a week away, but its lower price does not establish that it is a better month-long product. The table below therefore places only identical total-data and validity combinations beside one another. Both providers' observed EUR prices are used directly, without currency conversion. [1] [2]

Total data Validity PikoeSIM Nomad Difference on the listed match
1 GB 7 days €0.58 €3.57 €2.99
5 GB 30 days €1.54 €9.82 €8.28
10 GB 30 days €3.16 €16.07 €12.91
20 GB 30 days €6.40 €18.75 €12.35
50 GB 30 days €16.86 €27.68 €10.82

The final column is calculated by subtracting PikoeSIM's listed price from Nomad's. It does not value differences in customer service, network routing or refund conditions. Those features were not independently tested and should not be smuggled into a price-only verdict.

Nomad also lists 3 GB for 30 days at €8.04. No identical PikoeSIM 3 GB/30-day offer was observed in the retrieved catalogue, so it is not presented as an exact match. A smaller thirty-day allowance or a three-gigabyte package with shorter validity may suit the same person, but that is a practical alternative rather than an equivalent product. [2] [1]

Providers are omitted when a comparable fixed-data EUR offer was not reliably retrieved. Omission does not mean a provider has no suitable product. This is a bounded comparison of verifiable listings, not a complete market census.

Longer validity can matter more than the headline price

PikoeSIM's additional observed Greece options cover several different trip lengths. Combined with the five matching rows above, the following fourteen entries make up the nineteen fixed-data plans retrieved from its listing. [1]

Total data Validity Published price
1 GB 30 days €0.62
2 GB 30 days €0.70
3 GB 1 day €0.68
3 GB 5 days €0.78
3 GB 20 days €0.88
5 GB 10 days €1.20
5 GB 20 days €1.35
5 GB 45 days €4.12
5 GB 60 days €4.56
20 GB 20 days €5.10
30 GB 60 days €13.61
50 GB 20 days €13.00
50 GB 180 days €19.20
100 GB 60 days €30.64

Choose validity by counting the days on which you need service, including arrival and departure. A plan that expires just before an early airport transfer can be a poor saving. Conversely, there is no need to pay for a long period solely because it sounds more comprehensive when the trip is short and the data allowance is sufficient.

Consider a traveller taking a six-week trip who expects light use. A thirty-day product will not cover the entire period on its original validity, regardless of how much data remains. A longer-validity plan or a deliberately planned second purchase is the relevant comparison. Price per gigabyte alone misses that decision.

For repeat visits, a longer-validity allowance may be convenient only if the activation and expiry rules actually span those visits. Do not assume that switching the eSIM off pauses the clock. Establish the rule in the chosen product's terms before treating unused data as a reserve for another holiday.

Match the allowance to your own use

Begin with the activities that depend on mobile data: navigation, messaging, ticket retrieval, uploads, work calls or a laptop hotspot. These are more informative than a generic label such as "light traveller." Two people on the same island itinerary can have very different requirements if one spends evenings uploading video and the other waits for accommodation Wi-Fi.

Use a transparent estimate rather than a universal promise. For example, an assumed 0.5 GB daily over twelve days totals 6 GB. Under that assumption, a five-gigabyte allowance leaves a shortfall and a ten-gigabyte allowance leaves room for variation. The calculation is illustrative; it is not measured consumption for Greece.

Downloaded maps, saved booking details and offline entertainment can reduce dependence on a live connection. They also make a modest allowance less stressful. However, do not reduce the package so aggressively that one necessary video call or large document transfer becomes a problem.

A shared hotspot changes the calculation because the total allowance must support everyone using it. Confirm that tethering is permitted for the exact plan and remember that a laptop can consume data through updates or cloud synchronisation without an obvious streaming session.

Network labels do not establish nationwide performance

Nomad's Greece page lists NOVA and Vodafone networks and describes coverage and radio technology as dependent on the plan and local conditions. PikoeSIM publishes its own network information, which should be read at the individual-plan level. These details are useful for selection but do not establish a tested speed ranking between the sellers. [2] [1]

A destination-wide package is not a promise of an equally strong signal in every building, valley, beach or ferry journey. For an itinerary where connectivity is critical, make the important files available offline and arrange a second means of access rather than relying on one marketing coverage label.

For work, assess more than the data total. Ask about hotspot support, activation assistance and the procedure when the profile connects but data does not work. A small saving on the package is less significant than losing an essential working session. No claim of superior support response or latency is made here.

Activation, existing roaming and the final choice

Nomad states that its plan activates when connecting to the destination network, subject to the purchased plan's instructions, and that activation must occur within its stated purchase window. Its Greece page describes a sixty-day window after which automatic activation can occur. A plan bought far in advance therefore needs a date check, not just a price check. [2]

Confirm handset compatibility and network-unlocked status before paying, and read the installation instructions before scanning a code. Apple explicitly notes the unlocked-device requirement when using another provider. Keep the order reference accessible without relying on the connection you are trying to establish. [3]

Finally, eligible EU roaming may already supply the data you need in Greece under your home subscription's conditions. Verify the included allowance before buying a duplicate service. [4]

The practical recommendation is therefore conditional: use included roaming when it adequately covers the trip; among these observed standalone offers, choose the lower-priced exact match when its terms fit; and choose longer validity or a larger allowance when the itinerary requires it. That is more useful than declaring one brand universally best without specifying the product, price, duration or evidence behind the claim.
