eSimfly eSIM Data Plans for Mongolia

eSimfly does not provide a truly unlimited high‑speed data eSIM for Mongolia. The only plans listed under the “Unlimited” name give a fixed amount of high‑speed data, specifically 3GB per day for the duration of the plan. After the 3GB daily limit is reached, the speed is reduced, though the exact throttled speed is not specified in the available information. Because of this daily cap, these plans are not unlimited in the sense of offering unrestricted data usage.

Instead, eSimfly offers fixed‑data alternatives that may be more cost‑effective for travelers. For example, the Mongolia 50 GB 30 days plan provides 50 GB of high‑speed data for a month, while the Mongolia 25 GB 20 days plan offers 25 GB for 20 days. These plans give a clear data allowance and can be a better choice if you expect heavy data consumption during your stay in Mongolia.

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 provides 10 single‑country data plans and 23 multi‑country data plans that cover Mongolia. These plans span a price range of about $4.38 to $115.60, with data caps between 1 GB and 50 GB and validity periods ranging from 3 to 365 days. Some plans use a fixed data amount while others offer a daily data cap; many also allow tethering.
