Roamify does not provide a truly unlimited data eSIM for Mongolia. All of its listed plans for Mongolia have a fixed data cap, ranging from 5GB to 50GB, and each plan is valid for a set number of days.
Travelers who need a large amount of high‑speed data can choose from Roamify’s fixed data plans, such as the 50GB plan valid for 30 days or the 25GB plan valid for 20 days. These plans offer a substantial data allowance and can be more cost‑effective for most users unless they require an extremely high volume of data.
