nextSIM eSIM Data Plans for Mongolia

nextSIM does not provide a truly unlimited eSIM plan for Mongolia. Its plans that use the “Unlimited” name actually supply a fixed amount of high‑speed data—either 1 GB or 2 GB per day or per plan and then reduce the speed to 512 kbps or 2000 kbps once that amount is reached.

Alternatives are available in the form of fixed‑data plans. For example, nextSIM offers a 10 GB 30‑day plan that is specific to Mongolia, and global plans such as 20 GB, 30 GB, 40 GB and 50 GB for 30 days that also cover Mongolia. These plans give a set amount of high‑speed data and may be more cost‑effective for travelers who need a significant data allowance.

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 a range of data options for travelers to Mongolia, including 15 single‑country plans that keep the user’s data confined to Mongolia and 12 multi‑country plans that allow the data to be used across several destinations that include Mongolia. These plans span a price range of approximately $8.07 to $1, 268.83 and offer data caps from 1 GB up to 50 GB. Some plans feature a fixed data allowance, while others cap data usage on a daily basis, giving customers flexibility based on how they intend to use the data during their stay.
