Can I expect a mobile signal on inter-island ferries like Blue Star or Seajets while navigating the Greek Isles with eSIMFlyer?

For the majority of your journey, yes, you will! The popular ferry routes connecting the major Greek islands – think Piraeus to Mykonos to Santorini – are well-covered by land-based mobile towers. While you might encounter brief signal drops when the ferry ventures into deeper open water, your eSIMFlyer connection will typically be active for 95% of your trip. This means you can continue planning your next stop, browsing travel guides, or sharing stunning Aegean Sea photos almost continuously.
