Average data usage per day in Greece

Quick answer: most travelers use about 1.1 GB a day in Greece. Light users need around 0.3 GB, and heavy users with daily video calls and HD streaming around 2.7 GB.

Greece is island-hopping, so your usage depends on ferries and how remote your island is.

What shapes data use in Greece

  • Ferry days mean hours of scrolling or streaming, and coverage can fade at sea.
  • Larger islands have solid coverage; small ones can be patchy.
  • Beach days use very little.

Fixed GB or unlimited?

An average day comes to about 1.1 GB, which is close to what an unlimited plan gives you at full speed (1 GB a day, then 512 kbps). Unlimited suits heavy and unpredictable use. If you are mostly on maps and messaging, a fixed plan costs less. See Greece plans →

Frequently asked questions

How much data do I use per day in Greece?
About 1.1 GB a day for an everyday traveler using maps, messaging, social media and some streaming on cellular. Light users (maps and messaging) use about 0.3 GB a day, and remote workers with daily video calls and HD streaming use about 2.7 GB. Time spent on Wi-Fi does not count, so your real figure is often lower.
How long will a 5 GB plan last in Greece?
On cellular alone, about 4.7 days for an average user, about 17 days for a light user, and about 1.8 days for a heavy user. Using hotel Wi-Fi for streaming stretches it further.
Will my eSIM work on the ferries in Greece?
Near land, usually. Mid-crossing the signal can drop, and some ferries offer Wi-Fi. Do not rely on cellular for anything time-sensitive on the water.
What happens if I run out of data in Greece?
The eSIM stops passing data. There are no overage charges. You can buy a top-up or a new eSIM at any time. If your estimate lands close to a plan size, pick the bigger one.
