Yesim eSIM Data Plans for Mongolia

Yesim offers unlimited data eSIM plans for Mongolia with validity periods of 1 day, 7 days, 15 days, and 30 days. Prices range from $16.88 USD for the 1‑day plan to $100.16 USD for the 30‑day plan, and all plans allow tethering. The data is unlimited, but the provider notes that speed may be throttled after heavy usage, which is a typical Fair Usage Policy. If you need confirmation of the exact speed limits or the amount of data that can be used at normal speed before throttling, it is advisable to contact Yesim directly.

Yesim does not provide any eSIM plans for Mongolia that include a phone number or SMS capability. Travelers who need to receive or send standard SMS or make voice calls will have to rely on data‑only connectivity. Over the data connection, VoIP and messaging apps such as WhatsApp, Telegram, and iMessage can typically be used to make calls and send messages, but some destinations may restrict or block access to these services, so it is advisable to check app availability in Mongolia before purchasing.

Yesim offers eight single‑country data plans specifically for Mongolia, and it provides no multi‑country plans for that destination. The available plans range from 1 GB of data to unlimited data, with prices spanning from about $6.93 to $101.12. Some of the plans allow tethering, but they may experience throttling depending on usage.
