AeroSims eSIM Data Plans for Mongolia

AeroSims does not offer a true unlimited data eSIM for Mongolia.
The plans that carry the name “Mongolia Unlimited” provide a capped 2 GB per day allowance of high‑speed data, after which the speed is reduced to 1000 kbps. Travelers who need a larger or more predictable data supply can instead choose from fixed‑data options. For example, a 20 GB eSIM valid for 30 days or a 10 GB eSIM for 30 days gives full‑speed data until the allotted amount is used, and is generally a more cost‑effective choice for heavy data users.

AeroSims does not provide eSIM plans with a phone number or SMS capability for Mongolia; only data‑only plans are available.
Travelers can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging, though some destinations may block or restrict certain apps or services, so it is advisable to confirm that the apps you plan to use remain accessible in Mongolia before purchasing.

AeroSims lists eleven single‑country data plans specifically for Mongolia, and the provider does not offer any multi‑country plans for this country. The available plans cover a price range of approximately $8.65 to $234, with data allocations spanning from 2 GB up to 20 GB. Within those eleven options, some are structured as daily data caps while the remainder provide a fixed data amount for the entire validity period.
