eSIM Hero eSIM Data Plans for Mongolia

eSIM Hero does not provide a truly unlimited data eSIM for Mongolia. All available plans have a fixed data allowance; the highest‐capacity options include a 20GB plan for 30 days, a 10GB plan for 30 days, a 5GB plan for 30 days, and a 3GB plan for 15 days. These plans give high‑speed data for the entire validity period without a throttling threshold.

The plans that carry “Unlimited” in their name—Mongolia Unlimited 1 day, 3 days, 5 days, and 7 days—actually provide only 3GB of high‑speed data (per day for the multi‑day plans) and then reduce speed to 384 kbps once that amount is reached. Because they are not truly unlimited, travelers who need consistent, full‑speed data may find a fixed‑data plan to be more economical and reliable.

eSIM Hero does not provide a Mongolia eSIM that includes a local phone number or SMS capability. The provider offers only data‑only eSIMs for travelers in Mongolia. You can still make voice calls and send messages through VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but it is advisable to check that these services are accessible in Mongolia before purchasing, as some destinations may block or restrict specific apps.

eSIM Hero offers 10 single‑country data plans for Mongolia, with no multi‑country plans available. The price range for these plans falls between $5.00 and $86.00, while the data caps vary from 1 GB to 20 GB over validity periods of 1 to 30 days. Within the single‑country selection, 3 plans feature a daily data cap—limiting usage each day—whereas the remaining 7 plans provide a fixed total data amount for the entire validity period.
