RoameSIM eSIM Data Plans for Mongolia

RoameSIM does not offer a truly unlimited data eSIM for Mongolia. All of the plans listed, even the ones titled “Unlimited, ” provide a fixed amount of high‑speed data and then apply a reduced speed of 1 Mbps after 3 GB per day has been used. Travelers who need more data can choose fixed data bundles, such as the 20 GB plan valid for 30 days at $26.25 USD or the 10 GB plan for 30 days at $16.88 USD. These fixed‑data options can be more cost‑effective unless the user requires very high consumption levels.

RoameSIM does not provide a Mongolia eSIM that includes a local phone number or the ability to send and receive SMS. The provider offers only data‑only plans for the country. Travelers can use the data connection for internet‑based services such as WhatsApp, Telegram, or iMessage, but should verify that these VoIP apps function in Mongolia before purchasing, as some destinations may block or restrict specific services.

RoameSIM lists 12 single‑country plans that include Mongolia, while 9 multi‑country plans also cover Mongolia. Some of the available options are fixed data plans—these give a set amount of data for the entire validity period—while others are daily data cap plans that reset each day. Across both categories, prices run from roughly $4 to $183, with data caps ranging from 1 GB to 20 GB, and validity from 3 up to 365 days.
