10 Best South Korea eSIMs for Tourists: Unlimited Data & Phone Number

One of the eSIMs that our team tried in South Korea is this 5G eSIM from Klook. It was easy to install on our iPhones and Android phones (we didn’t have to scan a QR code), and it gave us a stable internet connection from SKT (a major Korean network) for 10 days. We liked that the data plans are budget-friendly and that we were able to use all apps and sites, including local ones like Naver, KakaoTalk, Papago, and more. You can get the same eSIM from Klook here from just $0.8 — get a 3-5% discount when you purchase with our promo code TRAVLISTS.

In a nutshell

• Award-winning. Aside from Klook, our team at Travlists also recommends BNESIM. This brand has consistently scored the highest on all our eSIM tests, and they have also received the World’s Best eSIM Provider Award six times at the World Travel Tech Awards. If you want an easy-to-use eSIM that is light on the wallet, get BNESIM’s 5G South Korea eSIM here from only $2.9 (get 30% off when you book with our coupon code TRAVLISTS).
• Unlimited data. If you are a heavy internet user who wants a nonstop internet connection when traveling, consider this South Korea eSIM from Ubigi. They have unlimited data plans for 7-30 days and offer connectivity from SK Telecom (like Klook). I also recommend this 5G eSIM from Yesim, which offers unlimited data with a free VPN for iPhone users. Get $6 off when you book Yesim’s eSIM here using our code TRAVLISTS2025.
• Phone number. Need to make calls and texts while traveling? You can get this eSIM with a phone number (+82) from LG U+ in Korea. As an alternative, you may also get this 5G eSIM from aloSIM. It comes with a free international phone number that can make calls and texts to both overseas and local lines. (We’ve tried both, and not one failed!)
• Best local eSIM providers. If you want to use a prepaid eSIM from a local carrier or provider in Korea, you can get this unlimited data eSIM from Superalink or this 5G eSIM with unlimited data from KT. These two are the most popular networks among locals. (I have been a KT postpaid subscriber for six years now and have never encountered any issues with the network.)

Fast & Reusable eSIM from Ubigi

Ubigi may be best known for their Japan eSIMs, but their digital SIM card for South Korea is also quite popular among tourists. Similar to their offering for Japan, their 5G Korea eSIM is easy to install (via app), capable of mobile hotspot, and can be topped up offline (great in case you lose data unexpectedly). However, the best thing about using Ubigi is that their embedded SIMs are reusable. Install it once, and you’ll never have to set up another eSIM on the same phone ever again. All you need to do is purchase a data pack for any of the 200+ destinations that Ubigi serves and turn on your eSIM upon arrival.

When we tested Ubigi in South Korea, we saw that it was, indeed, very easy to install on both iOS and Android smartphones. We also used it in one of our team members’ eSIM-capable Windows laptops. The speeds were consistent, and there was no throttling or downtime whatsoever.

South Korea eSIMs with Unlimited Data

Getting an eSIM with uncapped data is ideal for heavy users. If you’re someone who is always online while traveling, be it for navigation, streaming, social media, communications, translation, games, or work, you can choose to get any of the following eSIMs with unlimited data:

South Korea eSIM with Phone Number & Calls

If your trip requires you to have a local phone number in South Korea (+82), you can easily get one from LG U+ here, SKT, or World eSIM. Among the three, LG U+ offers data, calls, and texts for a small additional fee. (Note that to get a Korea eSIM with a phone number for calls and texts, you will need to visit LG’s counter at Incheon Airport and present your passport for activation.)

If you want to be able to make local and international calls or texts, you can get this 5G eSIM from aloSIM. It comes with a free international phone number, as well as minimal credits for calling and texting. Plans start at only $4.5, which is definitely cheaper than roaming.

We also make use of the free VPN that comes with any of their plans, which allows us to change virtual locations and enhance our privacy.
