Firsty does not provide an unlimited data eSIM plan for Mongolia. The provider’s plans in Mongolia are fixed‑data offerings, each supplying 8 GB for the specified validity period. For example, Firsty First Class (Mongolia) offers 8 GB for 1 day, 8 GB per day for 3, 5, 7, or 10 days. Choosing a fixed data plan can be more cost effective for most travelers, unless an extremely heavy data user requires unlimited usage.
Firsty offers eSIM plans for travelers to Mongolia, but none of the available plans include a phone number or SMS capability. The provider only sells data‑only eSIMs for that destination. Travelers can use voice and messaging applications such as WhatsApp, Telegram, and iMessage over the data connection to carry out calls and texts without a local phone number.
Firsty offers 16 single‑country eSIM data plans for Mongolia, with no multi‑country options available at present. The plans are divided into daily data‑cap variants, where the data allowance resets each day, and fixed data‑cap variants, which provide a set amount of data for the entire validity period. Across this selection the prices range from about $6.38 to $283.62, while the data caps span from roughly 1.5 GB up to 8 GB.
