What is the DataESIM internet signal like on the ferry to the Isle of Man?

DataESIM provides strong signal connectivity at the Douglas Sea Terminal and other port areas. However, during the open sea crossing on vessels such as the Manxman or Ben-my-Chree, you should anticipate a loss of internet signal for the majority of the journey. Our service relies on terrestrial cellular infrastructure, and beyond coastal waters, consistent connectivity cannot be guaranteed. Plan for offline activities during the transit.
