Will I maintain a signal on the 'Cat Cocos' inter-island ferry?

Updated April 22, 2026

Connectivity via CoreESIM is generally maintained for the majority of the Cat Cocos ferry journey between Mahé and Praslin. The route remains relatively close to the coastline of both islands, allowing for consistent signal reception from local towers. You can expect strong 4G/LTE service during departure from Mahé and upon approach to Praslin, with intermittent but generally stable coverage for much of the transit, enabling continued communication and light browsing.
