Ohayu eSIM Data Plans for Mongolia

Ohayu does not provide an unlimited data eSIM plan for Mongolia. Travelers who need larger data volumes can choose from a selection of fixed‑data options. For example, the Mongolia 50GB 90 days plan offers 50 GB for 90 days at $158.79 USD, while the 25GB Monthly plan supplies 25 GB for 30 days at $49.49 USD. These fixed‑data plans are valid for the specified duration and include tethering in most cases. Selecting a fixed data plan can be more cost‑effective for most users, unless they are extremely heavy data consumers who might prefer a network with higher maximum speeds.

No, Ohayu does not provide eSIM plans that include a local phone number or SMS capability for Mongolia. The available plans from Ohayu are data‑only, so travelers will have no cellular voice or text service tied to a Mongolian phone number.

Travelers who need voice or messaging can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, access to these apps can sometimes be limited or restricted in certain destinations, so it is advisable to verify the availability of your preferred services in Mongolia before purchasing an eSIM.

Ohayu offers six single-country plans and four multi‑country plans in Mongolia. The plans vary primarily by data allowance, ranging from 2 GB to 50 GB, and by validity from 14 to 90 days. Prices cover a spectrum from about $9.99 to $150.99, giving customers options that span low‑to‑high data caps and short‑term to medium‑term durations. The single‑country plans give the user data exclusively for Mongolia, while the multi‑country options include Mongolia plus additional destinations. The plans also include features such as tethering on some offerings, and they differ mainly in the total data amount rather than in a daily cap structure.
