Billion Connect eSIM Data Plans for Mongolia

Billion Connect does not provide an unlimited data eSIM plan for Mongolia. The available plans are fixed‑data packages, such as a 20GB eSIM lasting 1 day priced at $25.99 USD, a 1GB eSIM that can be used for 1 day for $5.34 USD, or a 1GB/day plan that extends over 3, 5 or 7 days. These options give travelers a clear data allowance with set validity periods and can be more cost effective for most users, unless they require an extremely high data volume that would make an unlimited plan preferable.

Billion Connect does not provide a Mongolia eSIM that includes a local phone number or SMS capability. The only offerings from this provider are data‑only plans that allow high‑speed internet access. Travelers who need to make voice calls or send text messages can rely on common VoIP applications such as WhatsApp, Telegram, and iMessage, which operate over the data connection without requiring a traditional phone number or SMS service.

Billion Connect lists 16 single‑country data plans for Mongolia and one multi‑country data plan that includes Mongolia. The provider offers both daily data cap plans and fixed data cap plans, with 14 daily‑cap options and 3 fixed‑cap options available. Across these plans, prices range from about $3.61 to $126.03 USD and data caps vary from 500 MB up to 20 GB, giving users a broad spectrum of choices for short‑term travel or long‑term stays.
