Simology eSIM Data Plans for Mongolia

Simology does not provide a true unlimited data eSIM for Mongolia. All of its plans for Mongolia are fixed‑data bundles. For example, the 50 GB plan is valid for 30 days, and the 20 GB plan is also valid for 30 days. The plans that carry “Unlimited” in their name actually offer 1 GB per day for the specified number of days, after which the speed is reduced to 1000 kbps. Choosing a fixed‑data plan can be more cost‑effective unless a traveler expects to use a very large amount of data.

Simology does not offer any eSIM plans for Mongolia that include a phone number or SMS capability. Travelers can only purchase data‑only plans from this provider. If a phone number or text messaging is required, they can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Mongolia before purchasing.

Simology offers 13 single‑country plans that can be used in Mongolia, with no multi‑country options available. The plans cover a price range from about $9.30 to $152.39 and data limits between 1 GB and 50 GB. Some plans allow daily data caps while others provide a fixed data amount for the entire validity period; the latter is common for longer‑duration offerings, whereas daily‑cap plans are typically used for short stays. Tethering is permitted on all plans, although the speed is reduced to 1 Mbps in certain cases.
