MoodSIM does not provide a truly unlimited data eSIM plan for Mongolia. The plans that carry “Unlimited” in their name are fixed‑data packages that allow a certain amount of high‑speed data per day and then throttle the speed after the limit is reached; for example, a 1 GB/day plan drops to 512 kbps once the daily cap is used.
If a traveler wants a straightforward data allowance, MoodSIM offers fixed data plans such as 20 GB for 30 days, 10 GB for 30 days, and 5 GB for 30 days. These plans offer predictable validity periods and can be more cost‑effective unless the user expects to consume data beyond the capped amounts.
