eSIMzio eSIM Data Plans for Mongolia

eSIMzio does not provide a truly unlimited data eSIM for Mongolia. The plans that carry the “Unlimited” name actually give 3 GB of high‑speed data per day and reduce the speed to 1000 kbps after that daily limit is reached, so the data is capped.

If a traveler needs a larger data allowance, eSIMzio offers fixed data plans such as the Mongolia 20 GB for 30 days, the Mongolia 10 GB for 30 days, or the Global 60 GB for 125 days. These plans give a set amount of high‑speed data that must be used within the validity period and can be more cost‑effective for most users.

eSIMzio does not provide a Mongolia eSIM that includes a local phone number or SMS capability. The provider only offers data‑only plans for Mongolia. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Mongolia before purchasing, as some destinations may block or restrict certain apps.

eSIMzio offers 12 single‑country plans and 13 multi‑country plans that include Mongolia. The available plans span a price range from about $2.03 to $228.34 and a data cap range from 200 MB up to 60 GB, with validity periods between 3 and 365 days. Some plans feature a fixed data amount, while others provide a daily data cap, allowing travelers to choose the option that best fits their usage pattern.
