What is the typical mobile network coverage in the more isolated islands and archipelagos of French Polynesia, such as the Marquesas or Tuamotus, with CoreESIM?

While primary islands like Tahiti and Bora Bora benefit from robust 4G LTE coverage via carriers like Vini and Vodafone Tahiti, mobile network penetration in the more remote archipelagos of French Polynesia, such as the Marquesas or Tuamotus, can be significantly limited. Connectivity often relies on sparse cellular towers or satellite backhaul, leading to intermittent service or even complete dead zones. CoreESIM leverages the best available local infrastructure, but even with this optimization, users should anticipate reduced data speeds and potential outages when venturing far from populated centers in these outlying regions. It is advisable to download offline maps and content before traveling to these areas.
