AeroSims eSIM Data Plans for Mongolia

AeroSims does not provide a truly unlimited data eSIM for Mongolia. The plans that carry the name “Unlimited” actually give 2GB of high‑speed data per day and reduce speed to 1000 kbps once that daily limit is reached, so the data is capped.

Travelers who need more data can choose from AeroSims’ fixed data plans for Mongolia, such as the Ulaanbaatar 20 GB/30 days plan or the Ulaanbaatar 10 GB/30 days plan. These plans offer a set amount of high‑speed data that must be used within the 30‑day validity period, and they can be more cost‑effective for most users unless very heavy data consumption is expected.

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.
