Network & Coverage

Stay connected across every corner of Ulaanbaatar

Your eSIM runs on Mobicom across Ulaanbaatar and on through Mongolia.

Mobicom
4G/5G coverage across Ulaanbaatar and on through Mongolia.
Where you will use it
the centre and Sükhbaatar squarethe ger districtsthe road to Tereljthe routes into the Gobi

Outside Ulaanbaatar and a handful of towns, Mongolia has essentially no coverage. The honest expectation is a connection in the city and nothing in the Gobi.

Does the Ulaanbaatar eSIM work outside the city?+
Yes, it is a Mongolia-wide plan. This page exists because people search for the city, not the country.
Can I share it as a hotspot in Ulaanbaatar?+
Yes. Tethering is allowed, which is what makes one unlimited line practical for a couple or a family moving around together. Keep in mind that hotspot traffic counts towards the daily full-speed allowance. Shared tablets and laptops get through it faster than one phone. The exact daily figure for every destination is on our fair use page.

How it works

Connected in
3 simple steps

1
Before you fly
Scan the QR code over Wi-Fi. About a minute.
2
On landing at UBN
Turn off flight mode. The line registers by itself.
3
Turn on data roaming
The step most travellers miss. It is not roaming in the billing sense; it is how the phone lets the eSIM use a foreign network.
✈️
Ready before you land
An hour's drive from a new airport well outside a city that holds half the country, and your eSIM is already working when you get there.

Frequently asked questions

Everything you need to know about your Ulaanbaatar eSIM

Is the data truly unlimited?+
There is a fair use policy, as with every unlimited plan on the market. We publish the details on our fair use page rather than bury them, so you can check before you buy.
When does my Ulaanbaatar eSIM activate?+
On its first connection to a local network, in practice when you switch off flight mode at UBN. Not when you pay.
Can I buy it weeks before the trip?+
Yes. It stays dormant until it first connects, so buying it together with the flight is fine.
Should I buy a SIM card at the airport instead?+
You can, but it means queueing after a flight and paying whatever the counter asks. An eSIM bought beforehand is already working before you reach passport control.
Which devices are compatible?+
Any eSIM-capable handset: iPhone XS and newer, recent Samsung Galaxy, Pixel 3 and newer. Dial *#06#. If an EID number appears, you are good to go.
Can I extend it if I stay longer?+
Often yes. While the eSIM is still active, open your personal eSIM page (the link is in your delivery email) and you will see there whether extra days can be added to your plan. If they can't, another eSIM for the same destination arrives by email and installs alongside the one you already have.
Only staying a few days?
A short trip is usually cheaper on a fixed data plan. Same networks, one price for the trip.
