nextSIM eSIM Data Plans for Mongolia

There are no truly unlimited data eSIM plans from nextSIM for Mongolia. Every plan listed has a fixed data allowance—1 GB, 2 GB, or larger amounts such as 10 GB, 20 GB, 30 GB, 40 GB, and 50 GB for 30‑day validity. Plans that carry the word “Unlimited” in the name still contain a capped data amount and specify a reduced speed that applies once the limit is reached, so they do not offer unlimited high‑speed data.

Travelers who need more data can choose from the fixed‑data plans. For example, the eSIM Mongolia 10GB 30Days Premium provides 10 GB of high‑speed 3G/4G data for 30 days and is specific to Mongolia, while the eSIM GLOBAL 50GB 30Days Premium offers 50 GB of high‑speed data for 30 days and covers Mongolia plus 157 other countries. These options give larger data allowances and, for heavy data users, can be more cost‑effective than the 1 GB or 2 GB “Unlimited” plans.

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 and 12 multi‑country plans that cover Mongolia. The catalog includes both fixed‑data plans, where a set amount of data is available for the entire validity period, and daily‑cap plans, where a maximum amount of data can be used each day. Across all plans the price ranges from roughly $8.12 to $1, 275.50 and data caps span from 1 GB to 50 GB, with validity periods between 1 and 30 days.
