nextSIM eSIM Data Plans for Mongolia

NextSIM does not provide a truly unlimited data eSIM plan for Mongolia. The plans that carry the “Unlimited” label, such as the eSIM Unlimited Standard and Unlimited Plus variations, actually come with a fixed data cap of 1GB or 2GB per validity period, after which the speed is throttled to 512 kbps or 2000 kbps respectively.

If a traveler needs a larger data allocation, NextSIM offers fixed data plans that can be more cost‑effective for heavy use. For example, the eSIM Mongolia 10GB 30 days Premium plan delivers 10GB of high‑speed data for 30 days at a price of $81.24 USD, and the eSIM GLOBAL 50GB 30 days Premium plan provides 50GB for 30 days at $1, 276.69 USD, giving access to Mongolia as well as many additional countries.

nextSIM does not provide Mongolia eSIM plans that include a phone number or SMS capability. The available plans from this provider are data‑only, so no voice or text messaging is included. Travelers can still use data‑dependent VoIP applications such as WhatsApp, Telegram, and iMessage for calls and messaging over the data connection.

nextSIM provides 15 single‑country data plans and 12 multi‑country data plans that cover Mongolia, giving customers a wide selection of options. The price of these plans ranges from about $8 to $1, 277, while data allocations span from 1 GB up to 50 GB. Some of the plans are fixed‑data packages, offering a set amount of data for a set period, whereas a smaller group—four plans—use a daily data‑cap structure that reserves a specific amount of data to be used each day within the validity period.
