I purchased the 8GB plan. At first, the total roaming usage was displayed as 5.8GB, and I thought I'd been scammed! However, even after watching videos and using social media for three days, it remained displayed as 5.8GB the entire time, and I was able to use it without any problems until the end! The connection was also good in Terelj and around the airport!

I used the SIM card during my vacation – the Seychelles, the UAE, and an unplanned transit through Ethiopia, Egypt, and Istanbul on the way back. The connection was good throughout. It was also sufficient for work – running MS Office applications.

Installation on Android/Samsung took longer than expected: 1. Dialing in the eSIM took several hours for activation/network/internet usability.

Ulaanbaatar is the only place where you can get a good signal, but Terelj has no signal at all, so be careful (T_T)
