What our travelers are saying about the voilà eSIM in South Korea

More than 500,000 travelers trust voilà to stay connected all over the world. Here is the feedback from those who used our eSIM in South Korea: SK Telecom network, 5G from Seoul to Busan and 4G all the way to Jeju Island, unbeatable prices, and all apps unlocked.

I had compared the Holafly eSIM and the Ubigi eSIM, but voilà was cheaper and had no blocked apps.

Trustpilot4.8Excellent
  • Remote work in Seoul, stable connection in coworking spaces

    Three weeks of remote work from Seoul, mostly in the Hongdae district. 50 GB data plan, and I was never short on data for nearly a month. The 5G from SK Telecom, the local provider that voilà relies on, held up perfectly in both coworking spaces and the subway. Big plus: free hotspot sharing, which was ideal for connecting my laptop to my smartphone during video calls. I used Kakao Maps to find my way, since Google Maps is limited. A friend uses a Saily eSIM, but for this kind of heavy usage, voilà was more reliable and the customer service was more responsive. The eSIM compatibility of my recent iPhone model was perfect, with one-click activation.

  • From Seoul to Jeju, more affordable than Saily

    Traveling alone in South Korea, from Seoul to Jeju. I had picked up a Saily eSIM in Japan, but for Korea, the Saily eSIM was more expensive, so I opted for voilà: more affordable and just as reliable on the local SK Telecom network. Downloading the prepaid eSIM and setting it up from France before departure took only two minutes—just a QR code scan. I enjoyed 5G in Seoul, signal everywhere in Jeju, and 20 GB of data was enough for typical use. Data tracking in the app, zero roaming fees. Perfect for traveling connected, with true simplicity.

  • The best price per GB, comparison done

    I did an eSIM comparison before leaving for South Korea. Among the best eSIMs, the Airalo eSIM uses LG U+ and ends up being more expensive per GB, whereas voilà is just €0.99 per GB on SK Telecom, the best rate on the market. Plans start at €1.70, valid for 30 days, with online purchase and installation on the website in two minutes—just scan the QR code, and the line activates as soon as you arrive in Seoul. No roaming fees, my usual number stayed reachable, and I had 20 GB of data. The value for money is unbeatable, making it an ideal eSIM for staying connected while traveling in Korea.

    Quentin Mercier
  • Great value for money, one small downside

    Very good value for money for South Korea. I was hesitating between Holafly, Airalo and voilà; the Holafly eSIM offers unlimited data but is expensive, with speed throttling after a certain limit, and voilà was much cheaper per GB. The SK Telecom network is reliable both in Seoul and in the rural areas of Jeju Island. The only downside: Google Maps doesn't work well in Korea, you have to download Naver Maps or Kakao Maps, but that's not the eSIM's fault. 10 GB prepaid data plan, enough for a week, instant activation upon landing at Incheon. I'll definitely get this prepaid eSIM again; it's a reliable and affordable product that works the moment you arrive.

  • Perfect for families, all the way to Jeju Island

    Family trip to Seoul and then to Jeju Island, 20 GB data plan. The SK Telecom network coverage was reliable everywhere, even in the rural areas of Jeju, perfect for enjoying the internet as a family. I had looked at the Nomad eSIM, but voilà was more affordable and hotspotting is free and included, ideal for connecting the kids' phones safely. Our usual number stayed active for calls. Automatic activation upon arrival, zero physical SIM cards. An ideal and reliable solution, accessible to everyone, which also suits families for everyday use.

    Hélène Vidal
  • Best eSIM plan for Seoul, better than Saily

    One-week stay in Seoul, 10 GB data plan. I had used a Saily eSIM before, but the Saily eSIM was more expensive and less reliable; I opted for voilà, at €0.99 per GB on the local SK Telecom network, with speeds over 500 Mbps in the city and signal in the Seoul subway. Google Maps is limited in Korea, so I enjoyed using Naver Maps and Kakao Maps without any issues. Instant activation, QR code scan, and the free data sharing allowed me to help out a friend. My banking apps and social media worked securely. A simple prepaid eSIM, perfect for daily use and the best eSIM plan for South Korea.

    Mathis_S
  • Top-notch experience

    I went to South Korea for 2 weeks (Seoul, Busan, Gyeongju, and Jeju) and I never had any network issues, except briefly on the KTX, but the train flies at 300 km/h. voilà relies on SK Telecom, the most reliable local network in the country, and you get to enjoy 5G in all the major cities. The prices are 2 times cheaper than on a Holafly eSIM and you can check your data in real time in the app. It's a true international eSIM, ideal for multi-destination travel: voilà eSIM plans are also the cheapest in Asia, so I'm continuing to use them for the rest of my road trip in China and Japan.

    Clara.H
  • Lightweight deal for Seoul, just no unlimited data

    A short long weekend in Seoul, I took the 5 GB data plan, which was plenty for transport, Naver Maps, and WhatsApp. The choice between the plan options, from 1 to 50 GB, depends on your budget and the length of your stay; it's more flexible and cheaper than a classic mobile plan. My only complaint: no unlimited data like with a Holafly eSIM, so for heavy streaming, go for 20 GB instead. For light use, it was excellent and much cheaper than unlimited offers. This prepaid eSIM shows the final price right at purchase, nothing is hidden.

    Hugo Lambert
  • Good provider, installation in 2 minutes

    For my trip to South Korea, I compared several South Korea eSIM providers before choosing voilà. Buying an eSIM, installing it, and downloading it took just two minutes through the app—one QR code scan and it was ready, much simpler than a local SIM card. The SK Telecom network was stable from Seoul to Busan (the other local operators being KT Korea Telecom and LG U+). 20 GB of data for two weeks was more than enough, with top-ups available in the app. No blocked apps: TikTok, social media, and banking apps all worked perfectly and securely. I highly recommend it for international travelers.

    Awa Diallo
  • Seoul-Busan road trip, reliable network everywhere

    Road trip from Seoul to Busan, 20 GB data plan. voilà is the provider I chose after comparing what the competitors offer: SK Telecom network (the Korean operators being SK Telecom, KT Korea Telecom, and LG U+), reliable coverage from the first to the last day. Immediate internet connection at Incheon Airport, banking apps and WhatsApp without any blocking, all safely. Free hotspotting is included, and I was able to top up 5 GB directly in the app in two minutes. A simple and reliable travel eSIM, perfect for all international travelers, and much cheaper than the more well-known brands.

    Romain Vasseur
  • Top-notch network on KTX, better than a Saily eSIM

    Two weeks across South Korea, from Seoul to Busan via KTX and then to Gyeongju. The SK Telecom network is fast: we enjoyed full-speed 5G in the city, exceeding 500 Mbps, and even had a signal on the high-speed train. I had a Saily eSIM before, but the Saily eSIM used a less stable network; with voilà, the internet connection never cut out. 50 GB of data for heavy use (streaming, free data sharing in coworking spaces), with data usage tracking in the app. Clearly the best eSIM for South Korea.

    Tommy33
  • Cheaper than a Holafly eSIM, just a little heads-up

    Great deal for South Korea. I had compared the Holafly eSIM and the Ubigi eSIM, but voilà was cheaper and had no blocked apps. The SK Telecom network was stable in Seoul and in the subway. The only little downside: you have to enable data roaming yourself in your device settings, but the activation instructions in the app are also very clear, so you'll manage easily. 10 GB of data was more than enough for a week of typical use, with top-ups available if needed. For the price, this prepaid eSIM remains the best eSIM plan, much more practical than a standard mobile plan.
