JamboSim eSIM Data Plans for Mongolia

JamboSim does not provide a truly unlimited data eSIM for Mongolia. All of its Mongolia‑specific plans list a fixed data allowance; the “Unlimited” names in the catalog refer to a daily high‑speed quota that is later throttled to 1 Mbps after the limit is reached.

Travelers who need a large amount of high‑speed data can choose fixed plans such as the eSIM Mongolia 20GB for 30 days, which offers 20 GB of high‑speed data valid for 30 days, or the eSIM Mongolia 10GB for 30 days, which provides 10 GB for the same period. These plans include tethering and are cost‑effective for most users.

JamboSim does not provide a Mongolia eSIM that includes a local phone number or SMS capability. The provider offers only data‑only plans for Mongolia, so travelers will need to rely on internet‑based services such as WhatsApp, Telegram or iMessage for voice and messaging. Because some destinations may restrict or block certain VoIP applications, it is advisable to confirm that the apps you need are accessible in Mongolia before purchasing a plan.

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.
