According to google the main/best network is Cosmote...though you could also use Vodafone or WIND if your phone will connect. If this is the first time abroad you 'may' need to let O2 know you are travelling/or are in Greece. I know this isn't strictly necessary but something I used to do. Also try and use WiFi wherever it's available @Anonymous
