Supera link does not provide an unlimited‑data eSIM for Oman.
Instead, the provider offers fixed data plans such as the “Global 109 Countries – 5GB/day” option, which delivers 5GB of high‑speed data per day for up to 30 days. This plan costs $175.68 USD for the full 30‑day period and can also be purchased in shorter durations (7 days for $42.01 USD, 10 days for $61.11 USD, 15 days for $83.07 USD, 20 days for $123.17 USD).
Choosing a fixed data plan can be more cost‑effective unless a traveller is an extremely heavy data consumer, in which case a higher‑cap or unlimited offer would be required.
