SimSmash eSIM Data Plans for Mongolia

SimSmash does not provide a truly unlimited high‑speed data eSIM for Mongolia. The plans that carry “Unlimited” in their names, such as the Mongolia Daily Unlimited 1GB/day and 3GB/day options, actually include a fixed data quota; once the allotted amount is used the plan ends or its speed may be reduced, though the exact throttled speed is not listed.

Travelers who need more data can choose from SimSmash’s fixed‑data plans for Mongolia. Examples include the 20GB for 30 days plan, the 10GB for 30 days plan, the 5GB for 30 days plan, and the 3GB for 30 days plan. These options may be more cost‑effective for users who do not consume extremely large amounts of data.

SimSmash does not offer an eSIM for Mongolia that includes a phone number or SMS functionality. The provider only sells data‑only plans for this destination. Travelers who need voice or text communications can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should check that these services are accessible in Mongolia before purchasing.

SimSmash provides seven single‑country plans for Mongolia, with data caps ranging from 1 GB to 20 GB, prices between $4.39 and $62.99 USD, and validity periods from 1 to 30 days. No multi‑country coverage plans are available, and some of the plans include tethering.
