gosimless does not provide an unlimited data eSIM for Papua New Guinea.
Instead, it offers fixed data plans that must be used within 30 days. For example, a 20 GB plan valid for 30 days costs $60.49 USD, and a 10 GB plan valid for 30 days costs $29.49 USD.
Choosing a fixed data plan can be more cost‑effective for most travelers, unless the user requires a very high volume of data beyond the provided allowance.
