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 eSIM plans for Mongolia that include a phone number or SMS capability. Only data‑only eSIMs are available from this provider for the country.

Users can still communicate while traveling by using VoIP applications such as WhatsApp, Telegram, and iMessage, which work over data connections. These apps allow voice calls and messaging without needing a local phone number or SMS service.

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.
