ByteSIM eSIM Data Plans for Mongolia

ByteSIM does not provide an unlimited data eSIM plan for Mongolia.
They offer a fixed‑data option, such as the 15GB for 10 days plan priced at $19.90 USD, which includes tethering and covers the entire country. Choosing a fixed data plan can be more cost‑effective for most travelers, unless a user requires a very high volume of data.

ByteSIM does not provide an eSIM for Mongolia that includes a local phone number or SMS capability. The only plans available for Mongolia are data‑only eSIMs.

If you need voice or text messaging, you can use VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection and do not require a local phone number or SMS services.

ByteSIM currently offers one single-coverage data plan for Mongolia. This plan provides a fixed data allowance, specifically 15GB of data, valid for 10 days, and costs between $19.90 and $19.90. They do not currently offer any multi-country plans that include Mongolia. Tethering is permitted with this plan.
