Nimbus eSIM Data Plans for Mongolia

Nimbus does not provide a true unlimited data eSIM for Mongolia. The plans that bear the “Unlimited” name give 3 GB of high‑speed data per day and the speed drops to 1000 kbps once that daily amount is used. Beyond that the data continues to run, but at a throttled rate. If you need a higher uncapped allowance, Nimbus offers fixed data plans such as the 20 GB plan valid for 30 days or the 10 GB plan valid for 30 days, which give larger data bundles without the daily cap and with normal speed until the bundle is exhausted.

Nimbus does not provide eSIM plans for Mongolia that include a phone number or SMS capability. All of its available plans for Mongolia are data‑only, which means travelers can use Wi‑Fi or cellular data for internet access and rely on VoIP applications such as WhatsApp, Telegram, or iMessage for voice and text communication. However, some destinations may restrict or block certain VoIP services, so users should confirm that the apps they need are accessible in Mongolia before purchasing a plan.

Nimbus offers a total of 18 plans for users in Mongolia, comprising 12 single‑country plans and 6 multi‑country plans. These plans include both fixed data caps, ranging from 1 GB to 20 GB, and daily data cap options. Prices vary from $3.49 to $109.49, with validity periods spanning 3 to 365 days. The daily data cap plans provide a set amount of data each day, whereas the fixed data cap plans offer a total data allowance that lasts for the entire validity period.
