Manet Travel does not provide an unlimited data eSIM plan for Papua New Guinea. Their catalogue contains only fixed data plans that specify a maximum amount of data and a validity period of 30 days.
The largest fixed option is 50 GB for 30 days, priced at $440.91 USD, with additional plans of 20 GB, 10 GB, 5 GB, and 3 GB. These plans can be more cost‑effective for most travelers, though they do have a hard data cap and are not suitable for extremely heavy data consumption.
