For tourists visiting Athens, an eSIM is generally the most convenient and cost-effective solution for mobile data. You can purchase and activate a Cellesim eSIM plan online before you even depart, avoiding the need to find a local SIM card vendor upon arrival at Athens International Airport (ATH). This ensures you have immediate connectivity for maps, transport apps, and communication as soon as you land.
