nextSIM eSIM Data Plans for Mongolia

nextSIM does not provide a genuinely unlimited data eSIM for Mongolia.
The plans that carry the word “Unlimited” actually have fixed data caps of 1 GB or 2 GB and, once that amount is used, the speed is lowered to 512 kbps or 2000 kbps, respectively.

For travelers who need more data, nextSIM offers fixed‑data plans such as the 10 GB 30‑day Premium plan, the 20 GB 30‑day Premium plan, and larger options capped at 30 GB, 40 GB, or 50 GB for 30 days. These plans give a larger, clear data allowance before any throttling occurs.

The nextSIM provider does not offer any Mongolia eSIM plan that includes a local phone number or SMS capability. Only data‑only eSIM plans are available for travelers heading to Mongolia. Pass‑through services such as WhatsApp, Telegram or iMessage can usually be accessed over the data connection for voice and messaging, but this is not guaranteed as some destinations may block or restrict certain VoIP services; travelers should confirm that these apps work in Mongolia before purchasing a plan.

nextSIM offers 15 single‑country plans and 22 multi‑country plans for Mongolia, for a total of 37 distinct data plans. The plans listed on eSIMDB span a price range from about $8.14 to $1, 279.70 and provide data caps from 1 GB up to 50 GB. Among them, some plans provide a fixed data amount, while others offer daily data caps; the daily plans are tailored for short‑term use, whereas the fixed‑cap plans are designed for longer trips up to 90 days.
