How much data do you need in Greece? A sizing guide
Real-world data usage numbers for a Greek trip: what navigation, maps, streaming and hotspot actually consume, and how to pick between 3, 10 and 20 GB without overpaying.

Buying too little data means an annoying mid-trip top-up; buying too much means bankrolling gigabytes you will never use. Here is the measured middle path, with the actual consumption numbers per activity and a decision rule per trip length.
What things actually cost in data
Approximate per-activity consumption on mobile (not Wi-Fi):
| Activity | Consumption |
|---|---|
| Messaging (WhatsApp, iMessage) | ~10 MB/hour active |
| Google Maps navigating + searching | ~5 MB/hour |
| Email and browsing | ~60 MB/hour |
| Social media scrolling | ~120 MB/hour |
| Music streaming | ~60 MB/hour |
| Video calls (FaceTime/Meet) | ~250–500 MB/hour |
| Netflix/YouTube HD | ~1.5–3 GB/hour |
| Laptop hotspot browsing | ~150 MB/hour |
| Laptop video calls (work) | ~700 MB+/hour |
Streaming is the whole game: an hour of HD video a day quadruples your plan size. Everything else combined is a rounding error next to it.
By trip length
Weekend (2–4 days): 3 GB is genuinely enough for light use; 5 GB if you want zero anxiety. In the table, 3 GB tiers start under €8.
One week (5–8 days): 5–10 GB. Without daily video streaming, 10 GB rarely runs dry even with generous social use. Current 10 GB packs run €17–22.
Two weeks: 10–20 GB depending on streaming habits. At this length, per-GB pricing is what separates good from mediocre deals — sort the table by €/GB.
A month / workation: if you work, hotspots and video calls push you to 50+ GB — that is unlimited-with-hotspot territory (easySim is the benchmark). If you are on holiday rather than working, 20–25 GB capped packs are usually the better price.
The three-question decision rule
- Will you stream video daily on mobile data? Yes → double every recommendation above or go unlimited. No → follow the base recommendation.
- Will you run a hotspot for a laptop? Yes → hotspot-allowed plans only; budget 10 GB/week minimum.
- Is your trip fixed-length and registered? If dates could slip, pay for the 30-day validity tier; a day-7 expiry mid-trip costs more in hassle than the €3 saved.
Wi-Fi changes the math
Greek hotels, ferries (Blue Star and most fast ferries have Wi-Fi, quality varies), and tavernas keep you on Wi-Fi for heavy lifting. Travelers who lean on Wi-Fi can halve the numbers above — the plan then just fills the gaps: navigation, tickets, messages, the taxi-booking moment at the port.
Size your plan, then check the live comparison for current prices — and if math is your thing, the roaming vs eSIM breakdown decomposes where each euro goes.
