JamboSim eSIM Data Plans for Mongolia

JamboSim does not provide a truly unlimited eSIM plan for Mongolia. All plans that carry “Unlimited” in their name actually limit high‑speed data to 3 GB per day; once that quota is reached, the speed is reduced to 1000 kbps. Therefore, the data allowance is capped and not truly unlimited in the sense of offering unrestricted high‑speed data.

If you need higher data without the daily cap, JamboSim offers fixed‑data options. For example, the Plan “eSIM Mongolia 20GB / 30 Days” offers 20 GB of high‑speed data for 30 days, and the Plan “eSIM Mongolia 10GB / 30 Days” provides 10 GB for 30 days. These plans are available alongside the daily capped “Unlimited” options and may be more cost‑effective for travelers who consume more data than the 3 GB/day limit.

JamboSim does not offer eSIM plans for Mongolia that include a local phone number or SMS capability. Only data‑only eSIMs are available from the provider.

Travelers can still make calls and send messages using popular VoIP apps such as WhatsApp, Telegram, and iMessage, which work over the data connection.

JamboSim offers a total of 30 data plans for Mongolia, split between 12 single‑country plans that cover only Mongolia and 18 multi‑country plans that include Mongolia among other destinations. The plans span a price range of $1.99 to $99.99 and a data cap range of 200 MB to 20 GB. Among the 30 plans, some are fixed‑data‑cap offerings—where a set amount of data is available for the validity period—while others use a daily data‑cap model, limiting the amount of data you can use each day.
