Opening hours and public holidays
It’s difficult to generalize about Greek opening hours, which are notoriously erratic. Most shops open 8.30/9am and close for a long break at 2/2.30pm. Most places, except banks, reopen around 5.30/6pm for three hours or so, at least on Tuesday, Thursday and Friday. Tourist areas tend to adopt a more northern European timetable, with supermarkets and travel agencies, as well as the most important archeological sites and museums, more likely to stay open through-out the day. If you need to tackle Greek bureaucracy, don’t count on getting anything essential done except from Monday to Friday, between 9.30am and 1pm.
To avoid disappointment, either phone ahead, check on the Greek Ministry of Culture website (http://odysseus.culture.gr), or time your visit during the core hours of 9am–2pm. Monasteries are generally open from approximately 9am to 1pm and 5 to 8pm (3.30–6.30pm in winter) for limited visits. Again, the opening times given for restaurants, cafés and bars can also be very flexible.
Phones
Three mobile phone networks operate in Greece: Vodafone, Cosmote and Q-Telecom/WIND. Coverage countrywide is good, though there are a few “dead” zones in the mountains, or on really remote islets. There are no roaming charges within the EU, so EU nationals pay the same price for calls, texts and data to numbers in their home country as they would at home; UK nationals should check the situation post-Brexit in 2019. For calling Greek numbers, however, you can save money by buying a pay-as-you-go SIM card from any of the mobile phone outlets. Top-up cards are available at all períptera (kiosks). North American users can only use tri-band phones in Greece.
Land lines and public phones are run by OTE who provide phonecards (tilekártes), available from kiosks and newsagents. If you plan on making lots of international calls, use a calling card, which involves calling a free access number from certain phone boxes or a fixed line (not a mobile) and then entering a twelve-digit code. OTE has its own scheme, but competitors generally prove cheaper. Avoid making calls direct from hotel rooms, as a large surcharge will be applied, though you will not be charged to access a free calling card number.
