What is the expected DataESIM connectivity performance on the Cook Strait Ferry in New Zealand?

DataESIM leverages robust carrier partnerships, but maritime cellular coverage on the Cook Strait Ferry can be inherently variable. You'll experience solid 4G/5G speeds when departing Wellington and approaching Picton. However, during the open water transit across the main strait and within the intricate fjords of the Marlborough Sounds, signal strength may fluctuate significantly or drop out entirely. For critical tasks, consider utilizing offline maps or downloading content beforehand.
