mysim24 eSIM Data Plans for Mongolia

mysim24 does not provide a truly unlimited data eSIM for Mongolia. The plans that carry “Unlimited” in their name give a fixed daily allowance of 1 GB or 2 GB at high speed, after which the speed is throttled to 512 kbps or 2 Mbps, respectively, and the allowance resets every 24 hours.

If a traveler needs a large amount of high‑speed data, mysim24 offers fixed data plans, such as 20 GB for 30 days at $78.77 USD or 10 GB for 30 days at $45.58 USD. These plans provide a single, non‑resetting data allowance and may be more cost‑effective for heaviest data users.

mysim24 does not provide eSIM plans for Mongolia that include a phone number or SMS capability. Only data‑only eSIMs are offered in that destination. Travelers who need to place calls or send messages can use VoIP apps such as WhatsApp, Telegram, and iMessage over the data connection, but they should verify that these services are accessible in Mongolia before purchasing, as some destinations may block or restrict certain VoIP applications.

Mysim24 supplies 29 single‑country data plans for Mongolia and does not offer any multi‑country plans in that destination. The plans range from $9.22 to $332.44 and provide data credits between 1 GB and 20 GB over validity periods of 1 to 30 days. Within those 29 plans, 14 are daily‑data‑cap options—data is refreshed each day—while the remaining 15 are fixed‑data‑cap plans that roll over until the validity expires.
