eSIM ProZone primarily offers robust connectivity in populated areas. For a Sepik River expedition, expect very limited signal, mostly 2G/3G, around larger villages such as Pagwi. Prolonged periods without data access are typical once you venture deeper into the remote stretches of the Sepik River, necessitating pre-downloaded content for offline use.
