A few quick questions answered
Does an eSIM work on older phone models?
eSIM support generally requires a phone from the past several years, so it’s worth double-checking your device’s settings before purchasing a plan.
Will it cover me if I take a day trip outside the city?
Yes, most eSIM plans for Greece cover the whole country, so heading to nearby coastal towns or historic sites shouldn’t interrupt your connection.
How do I know how much data to buy?
A short city break with regular maps and messaging use typically needs a modest data allowance, while heavier streaming or navigation-heavy trips call for a larger bundle.
