MobileSIM eSIM Data Plans for Mongolia

MobileSIM does not offer a true unlimited data eSIM for Mongolia. All of its Mongolia‑specific plans are fixed data plans, each with a set data allowance that must be used within a specified validity period. For example, the plan “Mongolia 20 GB for 30 days” provides 20 GB of high‑speed data that must be consumed within 30 days, and the “Global 60 GB for 125 days” plan gives 60 GB of data usable for 125 days. Choosing a fixed data plan can be more cost‑effective unless a traveler expects to use very large amounts of data.

MobileSIM does not offer an eSIM for Mongolia that includes a local phone number or SMS capability, so any purchase is a data‑only plan. Travelers can still use internet‑based voice and messaging services such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict certain VoIP apps, so it is wise to confirm that the apps you rely on will work in Mongolia before buying a plan.

MobileSIM provides 12 single‑country plans and 10 multi‑country plans that are valid for travel to Mongolia.
Among these, plans are offered with both fixed data amounts (16 plans) and daily data caps (6 plans).
The available plans range in price from about $2.30 to $165.00 and in data cap from 200 MB up to 60 GB, with validity spans of 3 to 125 days.
