Billion Connect eSIM Data Plans for Mongolia

Billion Connect does not provide an unlimited data eSIM for Mongolia. For travelers who need a fixed data allowance, the provider offers day‑by‑day plans that can be combined to create longer stays. For example, a 5‑day plan provides 1 GB each day for a total of 5 GB, while a 4‑day plan gives 1 GB per day for a total of 4 GB. Choosing one of these fixed data plans can be more cost‑effective for most users, while those who require significantly higher data volumes would need to look beyond these options.

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 provides 60 single‑country data plans for Mongolia, and there are no multi‑country plans available.
The plans are priced from $3.61 to $126.03 and come with data caps ranging from 500 MB to 1 GB, with validity periods that can be as short as one day or as long as 30 days.
Within those 60 plans, 58 are daily data cap plans that allot a specific amount of data each day, while the remaining 2 are fixed data‑amount plans that deliver a set amount of data over the validity period.
All plans allow tethering, and download speed may fall to 128 kbps once the daily or fixed data allowance is exceeded.
