Unfortunately, ORA eSIMs rely on standard terrestrial cellular networks, so they do not work once you’re out at sea.
Here’s why:
Cruise Ship Networks Are Satellite-Based: While docked or near shore, you might briefly pick up a local cellular signal—but once you’re fully at sea, cruise ships switch to proprietary satellite networks that ORA (and most eSIM providers) can’t access.
No Shore-Based Towers: ORA connects to partner providers’ land-based towers. At sea, there aren’t any shore towers available, so your ORA eSIM will lose signal.
