RedSim eSIM Data Plans for Mongolia

RedSim does not provide a truly unlimited data eSIM for Mongolia. The plans that carry the word “Unlimited” give 3 GB of high‑speed data per day and then reduce the speed to 1000 kbps for the remainder of the day. For travelers who need a larger, fixed amount of data, RedSim offers fixed data plans such as 20 GB for 30 days, 10 GB for 30 days, and 5 GB for 30 days, which can be more cost‑effective unless a user requires very heavy data usage.

RedSim does not provide eSIM plans for Mongolia that include a phone number or SMS capability. Only data‑only eSIM plans are offered for this destination.

Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging. However, some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the apps you rely on are accessible in Mongolia before purchasing a plan.

RedSim offers 11 single‑country data plans that cover Mongolia, plus 5 multi‑country plans that include Mongolia in their coverage. Most of the plans are fixed‑data caps (10), with a smaller set of daily data‑cap options (6). The overall price range for these plans is roughly US $3.19 to $88, while the data caps vary from 1 GB to 20 GB.
