Can I use the eSIM the moment I reach Istanbul Airport?

Yes. If you install your Yeohaengyusim eSIM before leaving Korea, it links up automatically with the Turkcell network right after landing at Istanbul Airport (IST). You don't need to look for a SIM kiosk in the airport or go through an ID registration process; you can use Google Maps and a translation app as soon as you clear immigration.

Does data work well even in the remote parts of Cappadocia?

In Cappadocia's main tourist areas such as Göreme and Ürgüp, 4G LTE connects reliably. The signal can weaken at hot-air balloon altitude, so it pays to download offline maps before your flight. On trekking routes through the rock formations or in remote valleys, the signal may weaken from time to time.

Will I need a lot of data while sightseeing in Istanbul's old town?

Istanbul has a great many sights, including Hagia Sophia, the Blue Mosque, the Grand Bazaar and Topkapi Palace. You get between them by tram (the T1 line) or on foot, so a real-time map app and a translation app are essential. The inside of the Grand Bazaar is such a maze that using an offline map alongside makes things even easier. Central Istanbul supports 5G too, so data speeds are on the fast side.

Do I need an e-Visa to enter Turkey?

Korean passport holders must obtain an e-Visa in advance when visiting Turkey. Just apply before departure on Turkey's official e-Visa site (evisa.gov.tr). Like your Yeohaengyusim eSIM, if you have it ready before departure you can start your trip right away after arriving, with no hassle.

Will the eSIM top up automatically or use up data during the flight from Korea to Turkey?

No data is used during the flight because airplane mode is on. The eSIM's data is only deducted when you are actually connected to a network and using it. Once you land at Istanbul Airport and turn off airplane mode, it links up automatically with the Turkcell network and data use starts from then.

Does eSIM work in Turkey?

Turkey supports eSIM, and plans start from ₩1,944. 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 Turkey?

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 Turkey eSIM use?

In Turkey it connects automatically to local carrier networks such as Turkcell · Vodafone Turkey · Turk Telekom (4G/LTE, 5G where supported). Population coverage is about 92%. 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 Turkey?

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 use tethering (hotspot) in Turkey?

Yes. In Turkey 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 Turkey. Just remember "set up before you leave, switch on when you arrive" and you can use the internet as soon as you land.

How many GB of data do I need for a trip to Turkey?

For mostly maps and messaging, we recommend about 1 GB a day; to use plenty of social media and photo uploads, about 2 GB a day. If you stream a lot of video or tether a lot, an unlimited plan is better. You can always buy more if you run short, so it is fine to choose a little extra at first.

Turkey is a country where thousands of years of history and dazzling nature coexist on the land where Europe and Asia meet. Wandering through Istanbul's Blue Mosque and Grand Bazaar, greeting the sunrise from a hot-air balloon above Cappadocia's strange rock formations, dipping your feet in the pure white limestone terrace pools of Pamukkale — Turkey is a country where every scene becomes a photo of a lifetime. As you travel across its vast territory, you constantly need Google Maps, real-time traffic information and a translation app. Getting a SIM at the local airport means long queues and unpredictable prices. If you install your Yeohaengyusim eSIM in Korea before departure, you are connected to fast internet right after landing at Istanbul Airport. So that you don't miss a single one of Turkey's wonders, Yeohaengyusim will be right there with you.

Why you really need a travel eSIM for Turkey

Turkey is a vast country, about 3.5 times the size of the Korean Peninsula. The distances from Istanbul to Cappadocia, Ephesus, Pamukkale and Antalya are considerable, so you will be using Google Maps, public transport apps and the local taxi app BiTaksi all the time. Without a stable data connection, planning your route is really hard. If you arrive at Istanbul Airport and try to buy a local SIM, you have the hassle of hunting for a kiosk and then going through an ID registration process. A Yeohaengyusim eSIM can be bought in Korea and fully installed before departure, so you can use the internet the moment you arrive. Running on the Turkcell network, it covers about 92% of Turkey, with fast 4G/LTE and 5G in major cities such as Istanbul, Ankara and Izmir. You can expect a stable connection in the rock landscapes of Cappadocia and the resort areas along the Mediterranean coast too. Keep your Korean SIM in as it is and activate only the eSIM for data, and you can still receive calls and verification texts to your Korean number while you are there, just as after you return home. To travel freely across vast Turkey, a single Yeohaengyusim eSIM is all you need.
