The Best eSIM for Greece in 2026

Greece has strong coverage across the mainland and its islands, and a travel eSIM is the easy way to arrive connected. Install a plan before you fly and land in Athens, Santorini or Mykonos already online.

Our recommended eSIMs for Greece

An eSIM avoids roaming charges and the local-SIM hunt, and a single regional Europe plan can cover Greece plus the rest of a European trip. Your home number stays active for calls and codes throughout.

Coverage in Greece

Coverage is strong across Athens, Thessaloniki and the main islands such as Santorini, Mykonos, Crete and Rhodes, as travel eSIMs use Greece's major networks. Very small or remote islands can be patchier.

How much data do you need?

  • ◆Light use (maps, messaging): 1–3GB per week.
  • ◆Normal use (social, photos, some video): a 5GB+ plan with top-up.
  • ◆Island-hopping or multi-country Europe: a regional plan or a larger allowance.

Getting connected on arrival

  1. 1Buy your plan before you fly, while you still have your home connection.
  2. 2Install the eSIM when prompted (scan the QR code or tap install in the provider's app), and label the line so it is easy to find.
  3. 3On arrival, turn the travel eSIM's data on and enable data roaming for that line.
  4. 4Set your home line to 'data off' so you are never billed for roaming, and keep it active for calls, texts and two-factor codes.

Yes. Travel eSIMs connect to Greece's major networks, with strong coverage on the mainland and main islands. Your phone must support eSIM and be unlocked.

Should I buy a Greece plan or a Europe plan?
