How does Simbye eSIM work for Mongolia?
Set it up before you travel
After your order the email arrives with a link and a QR code. You scan the code at home on Wi-Fi and the eSIM is already on your phone. Nothing is used up yet.
Arrive in Mongolia
Whether you land at Chinggis Khaan International Airport (UBN) about 52 kilometres south of Ulaanbaatar, fly on to Ölgii, Khovd, Mörön or Dalanzadgad, or cross the border by train at Zamyn-Üüd or Sükhbaatar: switch on data roaming for the Simbye line after you arrive and you are online.
Only now does the clock start
The validity period begins with your first connection to a Mongolian network, not with your purchase. Your own number stays active on your first SIM, this eSIM does not switch it off. Calls and texts keep running through your own carrier at your carrier's roaming rates, because the Simbye line is data only.
Check Device Compatibility
Make sure your device supports eSIM before purchasing
Which networks will you be on in Mongolia?
In Mongolia the eSIM connects to Mobicom on its own, with nothing for you to choose.
| Mobicom |
|---|
Mongolia has several mobile networks and our eSIM runs on Mobicom. There is nothing to pick: after you arrive you switch on data roaming for the Simbye line in your settings, and the phone connects by itself. You never type in an APN. If nothing happens after landing, turn flight mode on for ten seconds and off again, or restart the phone, which fixes it almost every time. Only if there is still no connection do you go into your mobile network settings, switch network selection from automatic to manual and pick Mobicom by hand.
How well you are connected depends heavily on where you are standing. In Ulaanbaatar, Darkhan and Erdenet 4G is the norm, and in Gorkhi-Terelj National Park just outside the city you usually have signal too. In the aimag centres such as Dalanzadgad, Mörön, Khovd, Ölgii, Choibalsan or Sainshand it is enough for maps, messengers and photos, sometimes on 4G, sometimes only 3G. Between the towns it thins out: there are pockets of coverage along the paved roads and in the soum centres, and often nothing in between. In the Gobi around Khongoryn Els, Yolyn Am and Bayanzag, in Altai Tavan Bogd and along much of Lake Khövsgöl beyond Khatgal you can go a full day or longer without a signal. That is not the eSIM failing, there is simply no mast out there. So download your maps, translator and tickets while you are still in town.
eSIM or a local SIM card in Mongolia?
For Mongolia the eSIM is the practical pick: the airport sits 52 kilometres outside Ulaanbaatar, and a local card wants your passport and tögrög in cash — though a Mongolian number does help with apps like UBCab.
| Feature |  Simbye eSIM |
Local SIM card |
|---|---|---|
| ID requirement | No registration, you buy online and nobody sees your passport | Mobile lines in Mongolia have to be registered to an ID document, so you hand over your passport |
| When you get online | Right after landing, because you set it up at home | Only after queueing at a counter, and the airport is 52 kilometres outside the city |
| Where you get it | By email, with a link and a QR code | Mobicom and Unitel desks in the arrivals hall, otherwise shops in Ulaanbaatar |
| Paying | Your own card in your own currency, price fixed in advance | In tögrög, often cash only, so change money or use an ATM first |
| Phone number | No Mongolian number, data only | Mongolian number included, handy for apps like UBCab whose sign-up code often does not arrive on a foreign number |
| Your own number | Stays active on your first SIM, the eSIM does not switch it off | The card takes the slot, and without a second slot your number is gone for the trip |
| Network | Mobicom, 3G or 4G depending on where you are | Choice of Mobicom, Unitel, Skytel or G-Mobile |
| Adding more data | Top up in your account wherever in Mongolia you are | Top up by app or terminal, usually in Mongolian only |
For most travelers the eSIM is the simpler choice: set up before departure, no queuing on arrival.

Frequently Asked Questions about Mongolia eSIM
Data, calls, real phone numbers, top-ups and setup — everything you need to know before you buy a Simbye eSIM.
Yes, an eSIM works in Mongolia. An eSIM for Mongolia is a digital SIM card built into your phone. You install it at home before you travel, and once you arrive in Mongolia and switch on data roaming for the Simbye line you are connected. All you need is a phone that supports eSIM and is not locked to a single carrier.
The eSIM in Mongolia uses Mobicom. Depending on where you are you get 4G or 3G. There is nothing to select and no APN to enter.
No, you don't get a Mongolian number with it. This is a data-only plan without a number, so you cannot make calls or receive texts over it. Your own number stays active on your first SIM; calls and texts over it are billed at your own carrier's roaming rates.
Signal in the Gobi or at Lake Khövsgöl is only in places: yes in Dalanzadgad, Mörön or Khatgal, but often not for a whole day out at the Khongoryn Els dunes, in Yolyn Am, at Bayanzag or in Altai Tavan Bogd. There are simply no masts out there, and that applies to every SIM card equally.
Not for this eSIM - no need to register or show your passport. Mongolia's registration rule applies to Mongolian lines you buy in a shop or at the airport. You connect as a guest on the Mobicom network and sign up nowhere.
No, it doesn't work in Russia or China - it works in Mongolia only. If you continue on the Trans-Mongolian railway via Zamyn-Üüd or Sükhbaatar, you need a separate eSIM for the neighbouring country.
You get an eSIM for Mongolia by ordering it online on this page and installing it before you fly. Choose the data volume, pay, and the QR code arrives by email - scan it and the profile sits ready on your phone. After landing in Ulaanbaatar you switch the line on and you are online.
An eSIM for Mongolia starts at 4,95€; the final price depends on data volume and validity, and the table above lists every Mongolia plan. City days with maps and messaging use little, while uploading photos from the countryside or sharing a hotspot with a laptop needs a bigger bundle.
How much data you need for Mongolia stays lean, since the sizes here are 1 or 3 GB. Maps, messaging and email in Ulaanbaatar cost roughly 100 MB a day, so 1 GB suits a short city stay and 3 GB a longer trip. Photo uploads from Terelj or the Gobi burn through a gigabyte quickly, and video or hotspot use faster still.
The eSIM that's best for Mongolia depends on where you go. Coverage decides everything here: this eSIM runs on Mobicom, solid in Ulaanbaatar, Darkhan, Erdenet and Gorkhi-Terelj, patchy once you are deep in the steppe or the Gobi. It is 1 or 3 GB, data only, with no Mongolian number. Right for maps and messaging, not for streaming your whole trip.
