SimSmash eSIM Data Plans for Mongolia

SimSmash does not provide a true unlimited data eSIM for Mongolia. All of the available offerings have a defined data cap, and after the limit is reached the speed is reduced. Travelers can choose fixed‑data plans instead, such as the 20GB plan for 30 days or the 10GB plan for 30 days, which give a large amount of high‑speed data before the throttled speed is applied.

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.
