No, eSimfly does not provide a truly unlimited high‑speed data eSIM for Papua New Guinea. The plans that have “Unlimited” in their names, such as the Oceania Unlimited 3‑Day, 5‑Day, 7‑Day, and 10‑Day options, actually offer 3GB of high‑speed data per day; once that daily quota is reached the speed is throttled to 1000kbps. If you need more data without an upper hard cap, you can choose one of eSimfly’s fixed data plans instead. Examples include the Oceania 20 GB 30 Days plan at $21.24 USD and the Papua New Guinea 10 GB 30 Days plan at $37.06 USD. These fixed‑data options give a larger total amount of high‑speed data and can be more cost‑effective for longer‑term use.
