Does it work on the Athens metro and out to Piraeus?

It does. Coverage is strong across central Athens, the metro lines and down to Piraeus port, though signal can briefly drop in deeper tunnel sections. Load your ferry tickets and directions before heading underground to be safe.

How much data do I need for a few days in Athens?

For a typical city break of maps, ride-hailing, social posts and restaurant bookings, most travellers are comfortable with 1-3GB. Stream video or hotspot a laptop and you'll want more - the same Greece plan also covers day trips beyond the city.

The short version.

A travel eSIM is data only. It sits next to your home SIM, so your number, texts and WhatsApp carry on as normal. Pick unlimited, priced per day, or a fixed bundle of GB if it's mostly maps and messages. Install it on Wi-Fi before you fly — the days only start once it first connects in Athens, and it finds a partner network on its own.

Before you fly

Athens eSIM questions, answered.

Yes. Activate it before you fly and it connects automatically to a Greek network such as Cosmote or Vodafone the moment you switch off aeroplane mode at Eleftherios Venizelos, so you can order a taxi or check the metro straight away.
