Can I expect to maintain a mobile signal with HotelESIM while traveling on Blue Star or Seajets ferries between Greek islands?

For the majority of your ferry journey between the Greek islands, you can indeed expect to have a reliable signal with HotelESIM. The main routes, such as those connecting Piraeus to Mykonos and Santorini, are well-covered by 4G networks. While there might be brief moments of signal loss in deep open waters far from land, you should be connected for over 95% of your trip. This allows you to plan your next island excursion, share stunning sea views, or simply stay in touch while enjoying the Aegean cruise.
