nextSIM eSIM Data Plans for Mongolia

nextSIM does not provide a truly unlimited high‑speed data eSIM for Mongolia. The plans that include “Unlimited” in their names actually allow a limited amount of high‑speed data—such as 1 GB on the eSIM Unlimited Standard 1 Day Mongolia plan—before the speed is reduced, for example to 512 kbps after the cap is reached.
Instead, users can choose from fixed‑data offerings. One example is the eSIM Mongolia 10 GB 30 days Premium plan, which supplies 10 GB of high‑speed data for 30 days, and other larger plans such as eSIM GLOBAL 20–50 GB 30 days Premium are available for more data. Choosing a fixed‑data plan can be more cost‑effective for heavy users compared to the capped “Unlimited” options.

nextSIM does not provide a Mongolia eSIM that includes a local phone number or SMS capability. The provider’s eSIM offerings for Mongolia are data‑only plans, so travelers cannot receive or send SMS or make regular phone calls with a local number. However, the data connection supports VoIP applications such as WhatsApp, Telegram, and iMessage, which can be used for calls and messaging over the internet.

nextSIM offers 13 single‑country plans and 12 multi‑country plans for Mongolia. The single‑country options include both fixed data amount plans and daily data cap plans—the latter typically suited for short stays, while the fixed plans provide a set amount of data for longer validity periods. The multi‑country options cover Mongolia along with several other destinations. Prices across these plans range roughly from $8.19 to $1,287.28, with data caps spanning from 1 GB to 50 GB and validity periods between one and thirty days.
