Athens eSIM FAQ
Will an eSIM work on my current phone?
Most phones from the past several years support eSIM technology, though it is worth confirming your specific model and unlock status beforehand.
Can I still receive calls and texts?
Since most travel eSIMs are data-only, you can keep your home SIM active for calls and texts while using the eSIM purely for internet access.
How much data should I get for a city trip?
It depends on how much you use maps and social media, but a moderate plan usually covers typical sightseeing, navigation and messaging comfortably.
