eSimfly eSIM Data Plans for Mongolia

eSimfly does not provide a truly unlimited data eSIM for Mongolia. The plans labeled “Mongolia Unlimited” actually offer a fixed 3 GB per day allowance, after which the data speed would normally be reduced, but the speed reduction is not specified. Because the plans have a capped daily data limit, they do not provide unlimited high‑speed internet.

Customers who need larger data capacities can choose from eSimfly’s fixed‑data plans instead. For example, a 50 GB plan is available for 30 days, and a 25 GB plan is available for 20 days. These plans give a generous amount of high‑speed data and may be more cost‑effective for travelers who expect to use more data than the daily 3 GB limit of the “Unlimited” package.

eSimfly does not provide an eSIM for Mongolia that includes a phone number or SMS capability. The provider currently offers only data‑only plans for that destination. Travelers who need voice or text communications can use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, which work without a local phone number or SMS support.

For travelers heading to Mongolia, eSimfly lists 10 single‑country data plans and 15 multi‑country options. The plans span a price range of roughly $4.38 to $90.60 and offer data caps from 1 GB up to 50 GB, with validity periods from 3 to 365 days. These plans include both fixed data amounts and daily data caps, with some allowing tethering.
