nextSIM eSIM Data Plans for Mongolia

nextSIM does not provide a truly unlimited data eSIM plan for Mongolia. The plans that include “Unlimited” in their names actually offer a fixed amount of high‑speed data—1 GB or 2 GB per day for the validity period—and once that limit is reached the speed is throttled to 512 kbps or 2000 kbps respectively. For travelers who need larger data allowances, nextSIM offers several fixed‑data options. For example, the eSIM Mongolia 10GB 30Days Premium plan gives 10 GB of high‑speed data valid for 30 days, and the global 20–50 GB 30Days Premium plans provide 20 GB to 50 GB of high‑speed data for 30 days, with coverage that includes Mongolia and many other countries. Choosing a fixed‑data plan is generally more cost‑effective for users who expect to use a lot of data.

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 offers 15 single‑country plans that include Mongolia and 12 multi‑country plans that cover the country as well. The single‑country options provide a fixed data amount—usually between 1 GB and 50 GB—for a set validity, whereas the multi‑country plans combine several destinations into one bundle, often featuring a daily data cap for more flexible usage. Prices range from about $8.27 to $1, 299.69, matching the overall data cap range of 1 GB to 50 GB and validity periods from 1 to 30 days.
