Athens Eleftherios Venizelos International Airport

Official Languages: Greek

English Is Widely Spoken in Athens, Thessaloniki, the Airports, the Ferry Ports and Anywhere That Sees Visitors, and Younger Greeks Handle It Comfortably. Road Signs on the Main Routes Carry Both Greek and Latin Script. You Will Meet Much Less of It in Mountain Villages and on the Smaller Islands

Mobile Network: Coverage Is Strong across the Mainland, the Cities and the Larger Islands, and 5G Now Reaches More than Nine in Ten People. The 3G Networks Closed in 2023, so a Handset Older than Roughly 2018 May Fail to Connect at All. Signal Thins on Mountain Roads and during the Longer Ferry Crossings

Roaming/SIM/eSIM: Anyone on an EU or EEA Plan Can Simply Use Their Home Allowance, Because the Rules That Removed Roaming Surcharges Run to 2032 — Check Only Your Fair Use Data Cap. Everyone Else Pays Heavily to Roam. An eSIM Is the Quickest Fix for a Compatible Phone, Because It Activates before You Land and Needs No Shop and No Paperwork. A Local Physical SIM Still Wins for a Long Stay or a Greek Number, Though It Needs an Unlocked Handset and an Identity Check in Person

Cards and Contactless Work Almost Everywhere, and Taxis, Kiosks and Market Stalls Have Been Legally Required to Take Them since 2024, and to Advertise the Fact on a Sticker. Any Single Purchase above 500 Euro Must Be Paid Electronically Rather than in Cash. Carry Twenty to Forty Euro Anyway, for Village Tavernas, Small Ferries and Church Candle Boxes

Tipping Is Modest and Genuinely Optional, Nothing Like the American Baseline. In a Taverna, Rounding Up or Leaving Five to Ten Percent for Good Service Is Normal, and a Service Charge Is Rarely Added. Cafes and Bars Keep the Loose Change, Taxi Fares Are Rounded Up, and Porters or Housekeeping Get One or Two Euro. Tip in Cash Where You Can, Because an Amount Added to a Card Slip May Never Reach the Staff

Plug Type: Type C and Type F

Voltage: 230 V, 50 Hz

Adapter: Greece Uses the Same 230 V Supply and the Same Type C and F Sockets as Most of Continental Europe, so Those Visitors Need Nothing. Travellers from the UK, Ireland, the US, Canada, Australia and Japan Need an Adapter. Chargers Handle Both Voltages, but a 110 V Heating Appliance Will Burn Out Here
