⭐️⭐️⭐️⭐️⭐️ The 7-day unlimited data eSIM I purchased from Klook worked perfectly during my Korea trip! The connection was fast, stable, and reliable everywhere I went. I was able to use apps like Naver Maps smoothly for navigation, upload photos instantly, watch videos, and stay connected all day without worrying about data limits. Setup and activation were very easy, and I had internet access as soon as I arrived in Korea. Highly recommended for travelers who need strong and unlimited data while exploring Korea! 🇰🇷📶

It covered my whole trip from Seoul to Busan. Albeit, there are times that it got slow. The convenience and the efficiency it brought me makes up for it. I already tried this with my Japan trip and it worked amazing and fast. That's why I availed again this time for my Sokor trip. I'll avail again in my next international trips since it's cheap and very worth it!

I had a great experience using the 5G eSIM for South Korea that I bought from Klook. Setup was super easy—I just scanned the QR code and was connected within minutes, even before leaving the airport. The connection was fast and reliable throughout my trip, especially in cities like Seoul and Busan. I was able to use Google Maps, social media, and messaging apps without any issues. The 5G speed was noticeable, and I didn’t experience any major lag or disconnections. I also liked that I didn’t have to remove my physical SIM, so I could still receive important messages from my home number. Plus, it saved me the hassle of finding a SIM card or pocket WiFi after landing. Overall, it’s very convenient, affordable, and perfect for travelers. I would definitely use this again on my next trip to South Korea. Highly recommended!

Super smooth, worked instantly in Seoul. Bought the eSIM for my 8-day trip. Activation was easy - before my flight and it connected as soon as we landed at Incheon. Speed was solid. Used Google Maps, IG, and Uber all day with no issues. Way cheaper. Will buy again for next month. Good value. Data was fast enough for navigation and socials. Used Naver Map the entire trip plus IG. Speed was crazy fast even in the subway. Compared to pocket WiFi, this saved me so much. No need to return anything at the airport too. 10/10 will buy again. Perfect in Seoul, Myeongdong, Itaewon, Goyang Stadium. Cheapest + most hassle-free data for travel so far 5/5. Turn on when you land. Takes 2 mins if your phone is unlocked. Fastest speeds, 5G common. “Unlimited” plans actually usable. Never got lost in Seoul thanks to this. No drops even in subway Line 2. Scanned QR at NAIA. Landed Incheon, toggled on eSIM + Data Roaming, worked instantly. Way less hassle than pocket wifi. 5/5 🌟🌟🌟🌟🌟 🌟🌟🌟🌟🌟🌟🌟🌟🌟🌟🌟🌟🌟🌟🌟🌟🌟🌟🌟🌟🌟🌟

How can I activate the eSIM directly from the Klook app?

  • Tap the “Activate” button and wait for the eSIM to get activated.
  • After activation, make sure the eSIM is installed on your device. You can check it from Settings > Cellular > SIMs.
  • You can name the eSIM in Settings > Cellular > eSIM > Cellular Plan Label.
  • Note: Be careful not to turn on the data roaming before arriving at your destination!
  • After arriving at the destination, please turn on eSIM data roaming and switch the cellular plan to this eSIM card to connect to the network.

How can I activate the eSIM with a QR code?

You can find the QR code from the booking details on the Klook app or on your Klook account.

The QR code should be visible next to the "Activate" button if your device is compatible with the eSIM and the eSIM plan. If not, you can scan the QR code with a device that is eSIM compatible by following these steps:

Name the eSIM at your convenience from the "Cellular Plan Label."

Do not turn on data roaming until you arrive at your destination

Android

Network & Internet > SIMs > Add Cellular Plan

The eSIM didn't get activated on my device. What should I do?

Check if your device is locked to a carrier, as eSIMs can't be activated on locked devices. Please contact your carrier for more information.

Can I scan one QR code with multiple devices?

No. You can use the eSIM only on one device. As such, one QR code can't be used multiple times or on multiple devices. Make sure to scan the QR code and activate the eSIM on the device you intend to use it on.

Should I turn on data roaming when I'm using the eSIM?

Yes. Make sure to turn on data roaming after you arrive at your destination. You can toggle it on from the eSIM settings.

An error occurred while I was installing the eSIM. What should I do?

The solutions depend on the error message you saw:

  • Cellular Plans from This Carrier Cannot Be Added:

Your device might be locked to a specific carrier. Please double-check from Settings > General > About > Carrier Lock. It should say "No SIM restrictions." If that's not the case, contact your original carrier to unlock the restrictions of your device.

  • Unable to Complete Cellular Plan Change:

It might be because too many eSIMs are installed on the device. Please double-check if your device has reached the maximum eSIM capacity, which eSIM service is on it, and try removing one of the unnecessary eSIMs.

Please make sure to turn on the mobile data on your device.

Please make sure that the eSIM plan hasn't been installed on another device.

Please make sure you have a stable connection while you're installing the eSIM.

  • This code is no longer valid:

Please make sure that the eSIM plan hasn't been activated on another device.

Please make sure you have a stable connection while you're installing the eSIM.

Try installing the eSIM through a different activation method. (There are two methods: In-app activation and QR code activation. You can try either on the same phone.)
