eSimfly eSIM Data Plans for Mongolia

eSimfly does not provide a truly unlimited data eSIM for Mongolia; the plans that include “Unlimited” in their names actually offer a fixed high‑speed allowance of 3 GB per day. After that limit, the speed would be throttled, but no plan offers unlimited high‑speed data without any cap.

Instead, eSimfly sells fixed‑data plans that can be suitable for most travelers. For example, the “Mongolia 50 GB 30 Days” plan provides a generous 50 GB of high‑speed data for one month, and the “Mongolia 25 GB 20 Days” plan offers 25 GB for 20 days. These fixed‑data options may give better value for users who need substantial data but do not require an unlimited plan.

eSimfly does not provide an eSIM for Mongolia that includes a phone number or SMS capability. The provider currently offers only data‑only plans for that destination. Travelers who need voice or text communications can use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, which work without a local phone number or SMS support.

eSimfly lists a total of 22 data plans that cover Mongolia, divided into single‑country and multi‑country offerings. Ten single‑country plans are available for Mongolian coverage, while 12 multi‑country plans include Mongolia as one of the destinations. The plans vary in both pricing and data allocation, with prices ranging from about $7.69 to $147.23. Data caps span from 1 GB to 50 GB, and validity periods can be as short as 3 days or extend up to 365 days. In addition to standard plans, some options provide a fixed data amount, whereas others offer a daily data cap, allowing users to choose the model that best fits their usage patterns.
