TooSim eSIM Data Plans for Mongolia

TooSim does not provide an unlimited data eSIM for Mongolia. Travelers can instead choose from fixed data plans such as Mongolia 10GB for 30 days or Mongolia 5GB for 30 days, which offer a set amount of high‑speed data. These higher‑allowance bundles tend to give a better value per gigabyte and are typically more cost‑effective for most users, unless they need an actual unlimited plan.

TooSim does not offer eSIM plans for Mongolia that include a phone number or SMS capability. All available plans from this provider are data‑only. Travelers who need calls or text messaging can still use VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection, but they should confirm that those apps are accessible in Mongolia before purchasing, as some destinations may block or restrict access to certain services.

TooSim currently offers 5 single-country data plans for Mongolia. These plans provide a fixed data allowance ranging from 1GB to 10GB with validity periods of 7 to 30 days. Prices for these plans range from $38.99 to $214.99. TooSim does not currently offer multi-country plans that include Mongolia. Tethering is permitted with some of the available plans.
