TooSim eSIM Data Plans for Mongolia

TooSim does not offer an unlimited data eSIM plan for Mongolia.
Instead, travelers can choose from a range of fixed‑data options. For example, a 10GB plan valid for 30 days is available for $214.99, and a 5GB plan valid for 30 days is offered at $130.99; both plans allow tethering. If a user expects to consume very large amounts of data, a fixed‑data plan can still be more economical than an unlimited plan from another provider, as TooSim’s Mongolia offerings do not include unlimited data.

TooSim does not provide eSIM plans for Mongolia that include a phone number or SMS capability. Only data‑only eSIMs are available from the provider for that country. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages, but no native telephony or SMS service is offered.

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.
