yaySIM eSIM Data Plans for Mongolia

The eSIM provider yaySIM does not currently offer an unlimited data plan for Mongolia. All available plans for Mongolian coverage are fixed‑data packages: MN_20_30 provides 20 GB for 30 days, MN_10_30 gives 10 GB for 30 days, MN_5_30 offers 5 GB for 30 days, and the MN_3_15 and MN_3_Daily plans deliver 3 GB for 15 days or 1 day, respectively. These options remain the only options for travelers to Mongolia and may be more cost effective for most users unless a very heavy data consumer requires a higher data allowance.

yaySIM does not provide eSIM plans that include a local phone number or the ability to send SMS in Mongolia. Only data‑only eSIMs are available from this provider for the country.

Travelers can still use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection for voice and text communication. However, some destinations may restrict or block certain apps or VoIP services, so it is advisable to confirm that the apps you need are accessible in Mongolia before purchasing a plan.

yaySIM offers eight single‑country data plans for Mongolia, with no multi‑country plans available. The plans range in price from roughly $13.74 to $84.15 and provide data caps between 1 GB and 20 GB, with validity periods from 1 day to 30 days.
