You step off the plane at Athens International Airport (ATH), the warm Greek air hitting you as you make your way through the terminal. Maybe you're heading straight to the ferry port for Santorini or Mykonos, or catching a short flight to Crete. Either way, you need to let your family know you've arrived, check the ferry schedule, and find your way to the hotel. With a Greece eSIM from Slashtel, you can do all that the moment you land, without hunting for a local SIM card or paying extortionate roaming fees.
Slashtel's Greece eSIM gives you data connectivity on a major local network. You buy online before you travel, receive a QR code by email within a minute, and install it on your phone. The plan starts from just $2.59, with no contract and no need for a local address. It's data only, so no local phone number, calls or SMS, but you can use WhatsApp calls over data. Hotspot is allowed, and top-ups are done online on the same eSIM. Days start counting only when it first connects at your destination, so you can install it at home and activate it when you arrive.
