Card-phones are quite widely available, the most common are supplied by OTE (the Greek equivalent of BT) but phones from other suppliers also exist. Generally, the OTE phones are good value and OTE phone-cards are readily available from the periptero (kiosks), grocery shops, etc. To get instructions displayed in English when using a card-phone, press the key marked ‘ i ’. To call a UK number, dial 0044 and then omit the leading '0' from the number. UK mobile phones should work in Greece, depending on your service supplier, and top-up cards may be available locally. Bear in mind that Kefalonia is very mountainous and some places are like the Twilight Zone for cell phones, e.g. around Skala.
