4S eSIM eSIM Data Plans for Mongolia

4S eSIM does not provide a truly unlimited high‑speed data plan for Mongolia. All plans that include “Unlimited” in the name actually have a hard data cap (for example 3GB, 5GB, 10GB, 20GB or 50GB) and specify a reduced speed of 1000 kbps once the limit is reached.

Travelers who need more data can choose from the fixed‑data options. For instance, the 50 GB plan is available for 5 days, 7 days or 15 days, and the 30 GB plan is offered for 15 days or 30 days. These fixed plans provide larger data allowances without the post‑limit throttling that occurs on the “Unlimited” plans.

4S eSIM does not provide a Mongolia eSIM that includes a phone number or SMS capability. Only data‑only plans are available from this provider for Mongolia. Travelers who need voice or text services can rely on popular VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection, although some destinations may block or restrict these services, so it is wise to confirm that the apps they rely on are accessible in Mongolia before purchasing a plan.

4S eSIM provides a total of 45 single‑country data plans for Mongolia, with no multi‑country packages available. Within those 45 plans the provider offers 38 fixed‑data‑cap options and 7 daily‑data‑cap options. Prices for the available plans range from about $4.32 up to $220.42, while the data caps vary from 714 MB to 50 GB, covering validity periods from 1 to 365 days.
