Does the internet work on the Mongolian steppe or at ger camps?

4G/LTE connection is possible in the city of Ulaanbaatar and around the main tourist spots such as Terelj National Park. However, once you go deep into the steppe or into the remote parts of the Gobi Desert, coverage can be patchy or drop out. We recommend saving Google Maps and any information you need offline before departure.

When I enter Mongolia, will I be connected right away at Ulaanbaatar's Chinggis Khaan Airport?

Yes. If you install your Yeohaengyusim eSIM before departure, it links up automatically with the Mobicom network the moment you arrive at Chinggis Khaan International Airport. You can open KakaoTalk and your maps right away, with no need to hunt for a SIM counter in the airport.

Can I also make calls or send texts to Korea while traveling in Mongolia?

The Yeohaengyusim eSIM is data-only by default. You can freely keep in touch with family and friends through internet-based messengers such as KakaoTalk, LINE and WhatsApp. Calls and texts on your existing Korean number are no problem if you keep your existing SIM and use the data-only eSIM alongside it.

Will I need a power adapter in Mongolia?

Mongolia uses Type C and Type E sockets. Korea's standard plugs (Type C compatible) can mostly be used as they are, so in many cases no separate adapter is needed. However, the power supply at ger camps and in remote areas can be limited, so be sure to bring a power bank.

When is the best season to visit Mongolia?

The peak season for travel to Mongolia is between June and September. In July in particular, the Naadam Festival takes place, where you can vividly experience nomadic culture through traditional wrestling, archery and horse racing. In winter (November–March), the bitter cold continues with temperatures dropping below minus 30 degrees, so you need to prepare thoroughly for the cold.

Does eSIM work in Mongolia?

Mongolia supports eSIM, and plans start from ₩12,039. Install it with the QR code you receive after buying, then just turn on data roaming after you arrive and you are connected straight away. There is no need to swap your SIM.

Travel eSIM or carrier roaming: which is cheaper for a trip to Mongolia?

For a short trip or light data use, a travel eSIM is usually cheaper. Unlimited roaming from Korean carriers costs about ₩11,000–₩15,000 a day, but with an eSIM you can buy just the days of data you need in advance. For a short trip for one or two people, an eSIM has a big advantage; for a family or very heavy data use, compare carrier unlimited roaming too.

Which carrier network does a Mongolia eSIM use?

In Mongolia it connects automatically to local carrier networks such as Mobicom · Unitel · Skytel (4G/LTE, 5G where supported). Population coverage is about 55%. It picks the network with the strongest signal automatically, so there is nothing to set up.

Can I keep using my Korean number while travelling in Mongolia?

Yes. The eSIM works as a data-only second line, so your Korean SIM and number stay as they are. Use the Yeohaengyusim eSIM for data only, and keep receiving calls, texts and KakaoTalk on your Korean number.

Can I add to or extend my Mongolia eSIM plan?

Yes. When you use up your data or the plan period ends, you can buy a new plan at any time. Keep using the eSIM profile you already installed; there is no need to install it again, so you carry on without interruption.

Can I use tethering (hotspot) in Mongolia?

Yes. In Mongolia you can share your eSIM data with other devices such as a laptop or tablet by tethering (hotspot). Shared data also comes out of your plan allowance, so if you tether a lot we recommend choosing a little more data.

Do I set up the eSIM before I leave or after I arrive?

We recommend installing it (registering the QR code) before you leave, while you have Wi-Fi. Data starts when you turn on data roaming after you arrive in Mongolia. Just remember "set up before you leave, switch on when you arrive" and you can use the internet as soon as you land.

Why an eSIM really helps in Mongolia

Mongolia is one of the most sparsely populated countries in the world. Once you leave the city of Ulaanbaatar, sparsely inhabited steppe and desert stretch on for hundreds of kilometers. In this kind of environment, getting or swapping a local SIM is far more of a hassle than you might think. You may not be able to get a SIM right at the airport, or the sign-up process at a local carrier's store may be complicated because of the language barrier. If you install a Yeohaengyusim eSIM via the app or a QR code before departing from Korea, it links up automatically with the Mobicom network the moment you reach Mongolia. You can use 4G/LTE data right away without a physical SIM, so you don't need to queue at the airport. A stable connection is possible not only in the city of Ulaanbaatar but also around Terelj National Park and the main tourist spots, and while trekking in remote areas you will feel even more at ease if you download offline maps in advance. Mongolia's coverage is about 55%, built mainly around the major cities and main travel routes. Coverage can be patchy at ger camps or deep in the steppe, so it pays to prepare offline content in advance.
