“I do not recommend this site for purchase. Before purchasing, I came across a number of negative reviews, but I decided to try my luck anyway. Here's my experience: In Uzbekistan, everything worked perfectly for one day, but the speed was terrible on the second day. In South Korea, everything worked well, but in China, everything worked well for two days, and then the internet simply disappeared, even though I still had plenty of data and time left. There is no support, and the AI agent responds by saying that I am doing something wrong.”

BNESIM South Korea

“I buy and use eSIM all the time and this was the WORST vendor/eSIM service. eSIM did not even work from the start, and no response from the vendor. eSIMDB should delist this vendor from the website.”

GIGAGO South Korea

“Doesn't have a local internet breakout like it says in the page, it uses Hong Kong operator and the lag is as bad as with the other sims that are 1/6 the price, so save your money”

Billion Connect South Korea

“I’ve used Billion Connect for multiple eSims abroad now, and I’ve found them great every time. Their customer service responds pretty quickly to any issues, and the sims are cheap and work well. Be aware the sims are mostly based in Hong Kong so if you’re geographically far from there the latency might be a little high, and you may need a VPN for things like TikTok to work, but I’ve had very few issues.”

Giga.Tel South Korea

“Beware: 1) No call/text available in South Korea. 2) Routed via HK so not the best service due to latency, but the same as most competitors in SK for eSIM. 3) Weird discrepancy on their website about price in USD vs charged amount ($1.00 USD more is charged than shown online). How do I know? I bought 3 eSIMs from Giga.Tel in South Korea, and over 10 from eSIM competitors. So far they are still the cheapest for the same 30GB and quality of service. Plus you can checkout with American Express in case of a dispute (MobiMatter does not allow Amex)”

TravelGator eSIM South Korea

“As soon as I land in a new country, it’s just a few simple steps to activate the eSIM—and I’m instantly connected!

The connection is way more stable than my original telco’s roaming, and best of all—no more swapping SIM cards or re-adding eSIMs every time I travel.

Definitely a game-changer for frequent travellers like me! 😊🌍”

“I went with this esim because of the great value and because I saw a positive review (after having tried a couple esims in the past with various companies that barely worked, I'm always a bit apprehensive to try one without and positive reviews) and I just wanted to second that review - airlink worked perfectly throughout Korea (have been connected to SK network the whole 3 weeks) and when considering price per GB, I doubt there are many better options.”

LinkeSIM South Korea

“Sim does not work for data in Korea. They also claim 24/7 support but they haven’t been online for the last 6 hours. Avoid company, I was left without any internet access when I landed and had to scramble poor free wifi to buy a different eSIM.

They still have not refunded me going to have to file a charge back. Avoid at all costs”

Saily South Korea

“Installation, price, set up was as easy as you can get. However, the speed in South Korea was abysmal (I had better experience in other country).
Usually slow but usable, but at times you opened Google Maps and it wouldn't even finish loading your "pins". So stressful to use, up to the point that one friend with the same SIM got himself a different one during the trip and I hopped Free Wi-Fis. Not what I bought this SIM for!”

Airhub South Korea

“I purchased an eSIM for my travel to South Korea. On their website, they say it 'operates on the SK Telecom Network in South Korea'; however, all traffic is routed to Hong Kong, which caused very slow 3g speeds and made it impossible to use some apps like ChatGPT.”

GLOBAL YO South Korea

“I bought two eSIM for Korea, one registered fine and worked but the other one did not register.
So I tried to contact them for help but there is no response ever.
I thought this was a good deal but it is not.
Try to avoid Global Yo as you won’t get any help or refund for your failing eSIM.”

I am really happy that I was able to have data connection anywhere I go. I recommend this esim if you are traveling and wanted to have an awesome roaming connection.”

South Korea Travel eSIM FAQ

Everything you need to know about using eSIMs in South Korea

How many travel eSIM brands (providers) are available for use in South Korea, and how many prepaid data plans are there?

There are about 140 providers and roughly 7, 600 prepaid data plans available for South Korea, and with a wide variety of options, travelers can easily find an eSIM that matches their needs.

Are there any unlimited data eSIM plans available for South Korea?

Yes, several eSIM providers offer plans that advertise unlimited data for stays in South Korea. These plans typically allow tethering, but the providers usually limit speed or throttle usage at higher rates. The available options range in price from around $2.65 to about $30.45 USD, depending on the chosen validity period and network capability. Users can select any of these unlimited plans, keeping in mind that speed restrictions may affect heavy data‑intensive activities.

What are the major mobile networks available for a travel eSIM in South Korea?

SK Telecom: The largest wireless carrier in South Korea, offering extensive nationwide coverage and a wide range of mobile services.
KT Corporation: A major telecommunications provider delivering comprehensive mobile services and playing a significant role in the development of 5G technology.
LG Uplus: A prominent mobile network operator known for its advanced network infrastructure and diverse mobile service offerings.

In addition to these major Mobile Network Operators (MNOs), South Korea has a growing number of Mobile Virtual Network Operators (MVNOs). MVNOs provide mobile services by leasing access from the major carriers, offering consumers alternative options. Notable local MVNOs include EyeVision Corp. and Sejong Telecom Inc. However, it's important to note that most travel eSIMs rely on the infrastructure of MNOs rather than MVNOs.

Can I get a travel eSIM with a phone number and SMS for South Korea?

Yes, travel eSIMs that include a phone number and SMS service are available for South Korea. Providers such as GlobaleSIM, MicroEsim, Roamify, Orange Travel, TravelKon, and Earth Esim offer these plans. They provide voice and SMS capabilities, generally inbound and outbound, but the associated phone numbers use foreign dialing codes such as +1, +010, 48, 33, and +33, which are not the local South Korean code of +82, so the numbers are foreign.

The pricing range begins at about $4.00 for a 1 GB, 7‑day package and rises to roughly $105.00 for a 20 GB plan that lasts 365 days. Validity periods vary from 1 day to 365 days, with most common options between 7 days and 30 days.
