nextSIM eSIM Data Plans for Mongolia

nextSIM does not have a true unlimited high‑speed data plan for Mongolia. All plans that carry the name “Unlimited” contain a fixed data cap—either 1 GB or 2 GB per day or in total—and after the cap is reached the speed drops to 512 kbps or 2000 kbps. Because the data allowance is limited, the plans are not unlimited in the sense of providing unbounded high‑speed internet.

Travelers who need more data can choose one of the fixed‑data options that nextSIM offers for Mongolia. For instance, the eSIM Mongolia 10GB 30Days Premium plan supplies 10 GB of high‑speed data for 30 days, and the eSIM GLOBAL 50GB 30Days Premium plan provides 50 GB for the same period, covering Mongolia and many other countries. These fixed‑data plans avoid the speed reductions that come with the “Unlimited” labels and may be more cost‑effective unless a user requires extremely high data consumption.

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 15 single‑country plans and 12 multi‑country plans that cover Mongolia, giving travelers a variety of options. Plans are priced from about $8.24 to $1, 295.18 and offer data caps ranging between 1 GB and 50 GB. Some of those plans are fixed‑data packages that give a set amount of data for the entire validity period, while others are daily‑data‑cap plans that reset the data allowance each day, allowing for predictable usage across the trip.
