Stixrs does not provide an unlimited data eSIM for Mongolia. Travelers can choose from fixed data plans that offer specific data allowances and validity periods. For example, the Mongolia Standard Data eSIM 50 GB 30 days plan gives 50 GB of high‑speed data for 30 days and costs $45.50 USD, while the Mongolia Standard Data eSIM 50 GB 90 days plan offers the same 50 GB for 90 days at $327.50 USD. Other available options include the Global Standard Data eSIM 20 GB 15 days plan, which delivers 20 GB for 15 days at $45.00 USD. Selecting a fixed data plan can be more cost‑effective unless you anticipate very heavy data usage.
