CoreESIM's network coverage along the Sepik River is generally sparse. You may encounter intermittent 2G/3G service near larger settlements like Pagwi or Ambunti, primarily supported by carriers such as Digicel PNG. However, significant portions of the river journey, especially in remote sections, will experience a complete absence of cellular signal. Device-grade accuracy indicates that satellite communication remains the most reliable option for consistent connectivity in these isolated areas.
