Simsima eSIM Data Plans for Mongolia

Simsima does not provide a truly unlimited data eSIM for Mongolia. The plans that carry the name “Unlimited” actually give 3 GB of high‑speed data per day and reduce the speed to 1000 kbps after that daily limit is reached, so the data is capped.

Instead, Simsima offers fixed data plans for Mongolia. For example, a 20 GB plan for 30 days costs $26.75 USD, and a 10 GB plan for 30 days costs $16.46 USD. These plans provide a set amount of high‑speed data that must be used within the specified validity period.

Simsima does not provide an eSIM plan for Mongolia that includes a phone number or SMS capability. The provider offers only data‑only eSIMs in this destination.

Travelers who need voice or text communication can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. However, some destinations may block or restrict certain VoIP services, so it is advisable to verify that the apps required for your communication needs are accessible in Mongolia before purchasing a plan.

Simsima’s portfolio for Mongolia includes nine single‑country plans and eight multi‑country plans. Across all plans the price ranges from about $5.63 to $113.24, while data caps vary from 1 GB up to 20 GB, with validity periods spanning from 5 to 365 days. The offerings encompass both daily data cap options—four plans that reset each day—and fixed data cap plans—thirteen plans with a set data allotment for the entire validity period.
