RoameSIM eSIM Data Plans for Mongolia

RoameSIM does not provide a truly unlimited data eSIM plan for Mongolia. All plans marketed as “Unlimited” actually supply 3GB of high‑speed data per day; after the daily limit is reached the speed is throttled to 1000kbps. Travelers looking for unlimited high‑speed access would need to combine several short‑term plans or purchase a different provider. As alternatives, RoameSIM offers fixed‑data eSIMs such as a 20GB plan valid for 30 days, priced at $40.60 USD, and a 10GB plan valid for 30 days, priced at $25.20 USD. These options deliver a larger total data allowance without the daily cap and may be more cost‑effective for most users.

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 offers 12 single‑country data plans and 13 multi‑country data plans that cover Mongolia. The plans’ prices range from $2.40 up to $208.60, and data caps span from 200 MB to 60 GB. Within the lineup there are 19 fixed data‑cap plans and 6 daily data‑cap plans, giving customers the choice between a set amount of data and a daily‑cap option.
