MobileSIM eSIM Data Plans for Mongolia

MobileSIM does not provide a truly unlimited eSIM plan for Mongolia. The plans that carry the name “Unlimited” actually allow 3 GB of high‑speed data each day; once that daily limit is reached, the data speed is throttled to 1000 kbps.

Travelers who need a larger, predictable data allowance can choose a fixed‑data plan instead. For example, MobileSIM offers a 20 GB plan for 30 days at $29, a 10 GB plan for 30 days at $18, and a 5 GB plan for 30 days at $11. These fixed‑data options can be more cost effective unless the user requires very heavy data usage.

MobileSIM does not provide eSIM plans for Mongolia that include a phone number or SMS capability. The provider offers only data‑only eSIM plans in that country. Travelers can still use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and text communication.

MobileSIM offers 12 single‑country plans and 8 multi‑country plans covering Mongolia. The available plans range from 200 MB to 20 GB of data and are priced between $2.34 and $89.00, with validity periods from three to sixty days. Some plans use a daily data cap, limiting the amount of data that can be used each day, while others offer a fixed data cap that applies for the entire validity period; a few of these plans include a reduced speed of 1, 000 kbps during part of their usage.
