BNESIM eSIM Data Plans for Mongolia

BNESIM does not provide an unlimited‑data eSIM for Mongolia; all plans have a fixed data allowance, such as 20GB, 50GB, or 100GB.
Travelers who need a large amount of data can choose from these fixed‑data packages. For example, a 100GB plan is available for 30 days at around $318 USD, or for unlimited validity at about $395 USD, while a 50GB plan costs roughly $165 USD for a 30‑day period or $206 USD for unlimited validity. These options may offer a more economical choice for most travelers unless their data usage is extremely heavy.

BNESIM does not provide an eSIM for Mongolia that includes a local phone number or the ability to send or receive SMS. The only eSIM plans sold by BNESIM for Mongolia are data‑only plans and do not contain telephony features.

Travelers who need voice or messaging functionality can use internet‑based services such as WhatsApp, Telegram, or iMessage over the data connection, which do not require a national phone number or SMS capability.

BNESIM offers 14 single‑country data plans for Mongolia and no multi‑country plans.
The available packages feature data caps ranging from 1 GB up to 100 GB and validity periods between “no expiry” and 30 days. Prices span roughly $6.34 to $387.12, with some plans allowing tethering. The lineup includes both fixed‑amount data options and duration‑based offers, giving consumers flexibility in choose the plan that best matches their usage.
