Astaroam eSIM Data Plans for Mongolia

Astaroam does not provide a truly unlimited data eSIM for Mongolia. The plans that carry the “Unlimited” name give 3GB per day and, once that amount is reached, the speed is reduced to 1000kbps.

Travelers who need more data can choose from Astaroam’s fixed data plans, such as the 20GB 30Days plan or the 10GB 30Days plan, which offer larger data allowances without a daily limit. These fixed plans may be more cost‑effective unless the user requires very high data consumption.

Astaroam does not provide an eSIM plan for Mongolia that includes a local phone number or SMS capability. Travelers looking to use Astaroam in Mongolia will only have access to data‑only service.

Although a phone number is not provided, users can still make and receive calls and send messages through popular VoIP and messaging apps such as WhatsApp, Telegram, and iMessage when connected to the data network. However, some destinations may block or limit access to certain apps, so travelers should verify that the services they rely on are available in Mongolia before purchasing.

Astaroam offers 12 single‑country data plans for Mongolia and does not have any multination coverage plans. The available plans vary in price from about US$3.17 to US$26.10, with data caps between 1 GB and 20 GB, and validity periods ranging from 3 to 30 days. Among these, five plans feature a daily data cap that replenishes each day, while seven provide a fixed data amount that remains constant throughout the validity period.
