What "unlimited" means here
Most unlimited plans give a fixed amount of fast data every day, then slow down until midnight. Enough for maps, messages and social media all day; not for video calls once the fast data is gone. See how the daily limit works.
If you use less than about 1 GB a day, a plan with a fixed amount of data is usually cheaper: the Mongolia page shows both for your number of days.
