What is CoreESIM's coverage like on Philippine islands such as Palawan (El Nido) or Siargao?

CoreESIM leverages primary Philippine carriers, providing robust 4G/LTE coverage in populated tourist centers across remote islands. For instance, in Palawan, you can expect reliable data services in towns like El Nido and Coron. Similarly, Siargao's main hubs will have strong connectivity. While deep-sea excursions or extremely secluded areas might experience signal attenuation, major resort zones and urbanized island sectors are well-served, ensuring consistent data for navigation and communication.
