aloSIM does not provide an unlimited data eSIM plan for Mongolia. The available plans are fixed data bundles, the largest of which offers 10GB for 30 days. Other options include 5GB for 30 days, 3GB for 30 days, 2GB for 15 days, and 1GB for 7 days, each priced separately.
Choosing a fixed data plan can be more cost‑effective for most travelers, unless you are an extremely heavy data user who requires continuous coverage beyond the bundle’s data limit.
