nextSIM eSIM Data Plans for Mongolia

nextSIM does not provide a true unlimited data eSIM for Mongolia. All plans listed under the “Unlimited” name actually have fixed data caps—ranging from 1 GB to 2 GB per day—and the speed is reduced after the cap is reached (for example, to 512 kbps or 2000 kbps). If an unrestricted data volume is needed, travelers can choose from the fixed‑data options such as the 10 GB 30 days premium plan priced at $82.05 USD or the 20 GB 30 days premium plan at $515.77 USD. These plans offer higher data allowances without the speed throttling that applies to the so‑called “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 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.
