Greece has three main carriers: Cosmote (Deutsche Telekom subsidiary, largest nationwide coverage with 5G in Athens, Thessaloniki, Patras, and the large islands), Vodafone Greece (broad urban 5G), and Nova (formerly Wind+Forthnet, best value). The eSIM Ahora connects to the strongest network. Plugs are Type C and F (standard European, same as Italy and Spain), 230V — no adapter needed from the EU. 4G coverage reaches Athens, Thessaloniki, Crete, Rhodes, Mykonos, Santorini, Corfu, and most inhabited tourist islands.
Athens Eleftherios Venizelos Airport (ATH) offers limited free WiFi. The currency is the euro; Eurobank, National Bank of Greece, and Alpha Bank ATMs accept foreign cards with no commission up to €600. Tips are 5-10%. Greece uses the Greek alphabet — tourist menus are in English but road signs are bilingual GR/Latin. The siesta hour (mesimeri, 2-5 PM) closes many shops outside Athens. For island ferries use ferryhopper.com — it aggregates all operators (Blue Star, SeaJets, Hellenic Seaways). "Tourist taxis" from the airport often charge €80-90 to downtown vs €38-45 official rate.
May, June, and September are the golden months — pleasant temperatures, warm sea, ferries running, manageable crowds. July-August is peak: islands fill up, Athens-to-Santorini ferries sell out days ahead, and prices double. October still allows beach time in Crete and Rhodes. Winter: only Athens and Thessaloniki run at full capacity; many islands close 70% of their hotels.
Cosmote, Vodafone Greece, and Wind/Nova cover Athens and Thessaloniki well. On the islands coverage follows main villages — Mykonos center and Fira (Santorini) have 4G/5G, but heading to remote beaches or coastal trails drops signal to 3G. Smaller Cycladic islands (Folegandros, Sikinos) have good signal at the port, mediocre inland. Large ferries have limited paid Wi-Fi.
Greece uses Type C/F plugs (230V, 50Hz). The euro is the currency. Schedules run late: dinners starting at 9 PM are normal, locals head out around 11 PM. Tips are 5-10%. The siesta hour (mesimeri, 2-5 PM) closes many shops outside Athens. For island ferries, download ferryhopper.com — it aggregates all operators.
A Greek SIM is affordable, but tourist plans usually require passport registration and a Cosmote/Vodafone store visit. The eSIM activated pre-flight removes the friction. For an Athens + 2-3 islands loop over 10 days, 10 GB suffices — you'll lean on Google Maps to find hidden tavernas and ferry routes.
