All GSM mobile phones (these are used in Europe and a few other countries) work in Greece. If you bring your own mobile phone with you, when you first switch it on in Greece you will be given a choice of which phone provider to use. Choose the one recommended by your home mobile phone service provider if, as is sometimes the case, this will give you better rates.

Certain companies provide a fixed charge per minute when "roaming" outside the country your phone service is from. Where this does not apply, you will pay fairly high rates for outgoing calls.

Incoming calls to your phone are expensive, because you pay for the international part of the call (from the country where your phone service is provided, to you, in Greece).
