ZenSim eSIM Data Plans for Mongolia

ZenSim does not provide a true unlimited data eSIM for Mongolia. The only plan with “Unlimited” in its name, Mongolia Unlimited STANDARD – 5 Days, actually offers 3GB per day; after that limit the speed is reduced, so it is not an unlimited offering.

Travelers who need more data can choose from fixed‑data plans. For example, ZenSim sells 10GB plans valid for 15 days or 30 days and 5GB plans with the same validity options. These plans give a set amount of high‑speed data and are often more cost‑effective than a plan that promises unlimited data but throttles speed after a threshold.

ZenSim does not provide a Mongolian eSIM that includes a phone number or SMS capability. Clients can only purchase data‑only plans for use in Mongolia. If voice or text communication is required, popular VoIP applications such as WhatsApp, Telegram and iMessage can be used over the data connection without the need for a local phone number or SMS service.

ZenSim offers 12 single‑country data plans for Mongolia. Among these, 11 are fixed‑data‑amount plans in which the allotted data remains usable for the entire validity period, while 1 plan is a daily‑data‑cap plan that replenishes the data allowance each day. Prices range from $18.00 to $216.00, data caps vary between 1 GB and 10 GB, and validity periods span 5 to 30 days. No multi‑country plans are available for Mongolia.
