Coverage in Mongolia: what to know
Mobicom has strong coverage here and in major towns; hotels and cafes commonly offer free Wi-Fi.
Mobicom is strong in Ulaanbaatar and larger towns, but Unitel is described as having the widest reach in rural and remote areas. Mobile and Wi-Fi access thins out once you leave the capital.

Questions people ask about a Ulaanbaatar eSIM
Does a Mongolia eSIM work in Ulaanbaatar?
Yes. A Mongolia eSIM runs on Mongolia’s own networks (Mobicom 4G), so the same plan works in Ulaanbaatar and everywhere else those networks reach in the country. There is no separate Ulaanbaatar plan to buy.
How much does an eSIM for Ulaanbaatar cost?
On 4 Nov 2026, Mongolia plans started at $4.79 and went up to $53.49 for the biggest. NUM’s 7-day pick was 3 GB for $9.69. The shop always shows today’s price, and the price on the pay button is the price you pay.
How much data do I need for Ulaanbaatar?
For a week of maps, rides, messages and photos most people use about 3 GB; for two weeks about 5 GB; for a month of social and video, 10 GB or more.
Will I be online when I land in Ulaanbaatar?
Install the eSIM at home on wifi, then switch the line on as the plane lands at Ulaanbaatar Chinggis Khaan International Airport (UBN). You are online walking off the plane, with no SIM counter and no airport wifi.
Can I use it as a hotspot?
Hotspot works on most plans, so one eSIM can get a laptop or a travel partner online too.
Why does my eSIM show another carrier’s name?
Many travel eSIMs are issued by one carrier and roam on local networks, so your phone can show the issuing carrier’s name while your data runs on a local network. Keep data roaming on for the eSIM.
Will it work on my phone?
Dial *#06# on the phone you’re taking. If you see an EID number, it takes an eSIM. Every iPhone from the XR and XS on does, and the SE from 2020, as do Google Pixel 3 and later and Samsung Galaxy S20 and later. The phone must be carrier-unlocked. Not sure? Text PHONE and your model and we’ll check.
When do I install it?
At home, on wifi, before you fly. Then switch it on when you land. Tell us your landing day and we text you the switch-on steps that morning.
Does it come with a phone number?
No. It’s a data-only eSIM. WhatsApp, LINE, iMessage and FaceTime all work over it, and your home number can stay on for calls and codes.
What if it doesn’t work?
If we can’t issue your eSIM, we refund you in full. If it won’t install or connect, text us and we help you get connected.
