Stellar eSim does not provide a truly unlimited data eSIM for Oman. The plans that carry the word “Unlimited” – for example, the “Oman eSIM Unlimited 1 day” and the “Oman eSIM Unlimited 30 days” – actually allow only 3 GB of high‑speed data (the 2 GB amount in the GCC‑wide variants).
Travelers who need more data can choose the fixed‑data options instead: a 100 GB plan valid for 60 days, a 50 GB plan valid for 15, 20, 30 or 90 days, or the consistently available 3 GB plans that run from 1 day up to 200 days. These larger plans are designed to cover moderate‑ to heavy‑usage periods and can be purchased in the desired validity window.
