Your Selection
Your plan only starts counting when the eSIM first connects at your destination — so you can buy today and travel in three weeks.
How does Simbye eSIM work for Mongolia?
Get connected in under 2 minutes
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.
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.
Why your home plan turns into a lottery in Mongolia
Mongolia appears on almost no mobile contract's list of countries where your data allowance simply carries over. That holds whether your contract is from Germany, the United States, Türkiye, Brazil or Japan.
What happens instead varies from carrier to carrier. Some apply a day pass, some bill per megabyte, and with some, roaming for Mongolia is only unlocked once you call them first. The price is rarely where you look for it, and often you only learn it on the bill after the trip. For a country where you have little control over your connection anyway, that is the least pleasant combination.
A prepaid eSIM flips it around. You pay a fixed amount upfront for a fixed amount of data, and it does not grow from there. When it is used up it stops, or you top up. No contract, no notice period, no surcharge and no invoice landing in your postbox four weeks later.
Where the network reaches, and how to plan around the gaps
The rough rule in Mongolia is that where people live there is signal, and where there is pasture there usually is not. Almost half the country lives in Ulaanbaatar, where 4G is a given, as it is in Darkhan and Erdenet.
Out in the countryside you navigate by the centres. Aimag capitals such as Dalanzadgad in the southern Gobi, Mörön on the way to Lake Khövsgöl or Ölgii in the Altai have coverage, and so do many soum centres, sometimes only on 3G. In between lie hours without a single bar. At ger camps the one spot with signal is often the rise behind the camp, and that is exactly where everyone stands with a phone in the evening.
Plan for it from the start. Download the offline map for Mongolia, save tickets and bookings as screenshots, and tell people at home you will be out of touch for a day or two. And since this plan is a deliberately lean 1 or 3 GB: turn off automatic updates and cloud backups in the background, and save video for the hotel Wi-Fi.
How much data do you need in Mongolia?
So you can work it out instead of guessing: how much an hour costs in the apps you actually use on holiday.
Just staying reachable
1–3 GB
Messages, the map now and then, checking mail. Everything else runs on the hotel Wi-Fi.
An ordinary holiday
5–10 GB
Navigating, social media, uploading photos, a few videos in the evening.
Out a lot, or a laptop along
20 GB and up
Streaming in the evening, video calls home, keeping a laptop or tablet online through your phone.
Data used per hour
The Netflix and Spotify figures come from the providers themselves (Netflix Help Center, Spotify Support, retrieved 28 Aug 2026). The rest are network-operator estimates (o2, Vodafone, EE) and vary with picture quality and reception.
