Simsima for Mongolia FAQ
Does Simsima offer unlimited data eSIM for Mongolia?
Simsima does not provide a truly unlimited data eSIM for Mongolia. The plans that carry the name “Unlimited” give 3GB per day of high‑speed data; after that daily limit the speed drops to 1000kbps. Consequently high‑speed data is still restricted to the 3GB/day quota.
If you need more data, Simsima offers fixed data plans in that region. For example, a 20GB plan valid for 30 days costs about $27.27 USD, and a 10GB plan valid for 30 days costs roughly $40.13 USD. These fixed‑data plans might be more cost effective for travelers who use a large amount of data.
