Billion Connect eSIM Data Plans for Mongolia

Billion Connect does not provide an unlimited data eSIM for Mongolia. The provider’s available plans for the country have fixed data allowances, with the largest offering 100GB for 1 day. Other examples include a 50GB plan and a 1GB/day plan. For travelers who need large amounts of data and want a predictable cost, choosing a fixed data plan such as the 100GB option is more cost‑effective; unlimited data is not offered.

Billion Connect does not provide a Mongolia eSIM plan that includes a local phone number or SMS capability. All eSIMs sold by this provider for Mongolia are data‑only, offering internet access without voice or text services. Travelers who need voice and messaging can typically use VoIP applications, such as WhatsApp, Telegram, and iMessage, over the data connection. However, some destinations may block or restrict certain apps or VoIP services, so users should verify that the applications they rely on will work in Mongolia before purchasing a plan.

Billion Connect offers 16 single‑country data plans and 9 multi‑country plans that include coverage in Mongolia. The plans span a price range from roughly $3.61 to $126.03, with data caps between 500 MB and 100 GB and validity periods from 1 to 30 days. Among these, 14 plans feature a daily data cap while 11 provide a fixed data amount. The days‑based plans limit the amount of data you can use each day before the cap is reached, whereas the fixed‑data plans offer a total data allotment that is consumed over the validity period.
