MeSIM does not provide a truly unlimited data eSIM for Oman. The plans that carry the word “unlimited” in their name actually give a daily high‑speed allowance—such as 500MB/day, 1GB/day, 2GB/day, or 3GB/day—and once that daily limit is reached the speed is throttled to 384 kbps. Therefore these plans are not unlimited in the sense of having no data cap.
Travelers who need a large amount of data can choose from MeSIM’s fixed data plans, which offer a set amount of high‑speed data for a specified validity period. Examples include the 50GB 30‑day plan, the 50GB 3‑day plan, and the 50GB 5‑day plan. These fixed plans can be more cost‑effective for heavy data users and provide a clear data allowance without the speed reduction that follows the daily limits of the “unlimited” plans.
