JamboSim eSIM Data Plans for Mongolia

JamboSim does not provide a true unlimited data eSIM for Mongolia. The plans that carry the word “Unlimited” give a capped high‑speed allowance of 3 GB per day, which totals 9 GB for the 3‑day plan, 15 GB for the 5‑day plan, and up to 90 GB for the 30‑day plan. Once the 3 GB/day limit is reached on those plans, the data speed is throttled to 1000 kbps. For travelers who need higher raw data volumes without such caps, JamboSim offers fixed‑data options. Examples include a 20 GB‑30‑day plan priced at $11.99, a 10 GB‑30‑day plan at $8.99, and a 20 GB‑365‑day plan at $77.99, all of which include tethering and no speed reduction once the data cap is hit. Choosing a fixed‑data plan can be more cost‑effective for users who require substantial data but do not need an unlimited allowance.

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.
