How reliable is EastESIM's signal coverage on the Cook Strait Ferry between New Zealand's North and South Islands?

While EastESIM prioritizes robust connectivity, the Cook Strait Ferry journey can present challenges. You'll enjoy strong signal as you depart Wellington and approach Picton. However, expect intermittent or dropped coverage across the open waters of the Cook Strait and within the more secluded bays of the Marlborough Sounds. We recommend downloading any essential maps or entertainment beforehand, though you might catch a signal burst near coastal areas for a quick update.
