How reliable is EastESIM's coverage for a Sepik River adventure in Papua New Guinea?

Updated April 22, 2026

While Papua New Guinea offers incredible adventures, connectivity can be quite challenging in remote regions like the Sepik River. EastESIM aims for the best possible coverage, but along the Sepik, particularly between villages, you should anticipate intermittent or no signal. Major hubs like Wewak or Madang will have better service, but deep into the river system, the priority is often experiencing the journey unplugged. We recommend downloading maps and essential information offline before venturing into the more isolated stretches to ensure a smooth trip.
