If you’re looking for the best Korea SIM card for tourists, we can help.
We’ve compiled a list of all the Korea travel SIM cards that can be pre-ordered and picked up at the airport.
We used a Korea data SIM card from KT Olleh ourselves and we can honestly say that it was a big advantage.
Not only to use excellent navigational apps such as Naver apps, Google Maps is pretty useless in South Korea, we also loaded a lot of other Korean apps on our phone. Thanks to these apps we could eat where the locals eat, translate Korean texts and it also became much easier to interact with Koreans.
I’ve listed some of the apps we used further down in this article.
We cover all the important details about the various Korean Sim card for foreigners, as well as all the aspects that you need to keep in mind when you’re making your selection.
Read on to find the best Korea prepaid SIM card for you.

Why buy a Korea prepaid SIM card
It’s easy to travel independently around Korea, especially if you can use your smartphone as your travel companion.
We used our data connection a lot in South Korea, the country has several very useful apps for tourists.
Here are the apps that we used the most during our road trip in South Korea:
- XE currency provides real-time conversion rates between the South Korean Won and your home currency.
- Kakao Metro guides you through Seoul’s spaghetti-like metro network. The app also works in Busan, Daegu, Gwangju, and Daejeon.
- Kakao T, this app enables you to call and pay for a taxi similar to Uber. You can also use it to rent an electric bike.
- Mangoplate, information on nearby restaurants including reviews
- Papago, fast and accurate translation of South Korean to 13 languages including English, French, German, Japanese and Chinese. It works offline and the quality of the translations beats those of Google Translate.
- Emergency Ready, an app provided by the Ministry of Interior and Safety. The app contains information about shelters, police and fire stations. The government will share updates in case of natural disasters such as typhoons. ( Google Play – Apple Store)
- Visit Korea, an app provided by the Korea Tourism Organization. It contains opening hours, prices and lots of other useful information about the many sights of the country. To get the app, scroll to the bottom of the page and click on “KTO Mobile apps”
- If you go to Lotte World or Everland you can use the apps of those theme parks to check the waiting times at the attractions.
Roaming costs are insane and Korea prepaid SIM cards are relatively cheap. This makes it a good investment, even if you won’t be using your data connection on a daily basis.
South Korea has the world’s best 4G network so it would be a shame not to use it when you visit the country.
Larger cities such as Seoul also count numerous WiFi hotspots. We tested these with mixed results. Our experience with these WiFi hotspots is described below.

Free WiFi in Korea
You can find over 500,000 public WiFi hotspots in Seoul alone. With this number, you would think that a data connection is a superfluous luxury but it turned out that it was not.
First of all, it is a hassle to register your phone over and over again at each new hotspot that you come across. If it would stop there it wouldn’t be such a big thing.
Some registration forms are in Korean only though, making the task extra tedious. And then, to make things worse, after you have finally deciphered the form, you’re sometimes met with the notice that they only accept Korean phone numbers.
We went through this process a few times only to decide that the low cost of a local tourist SIM card, or a pocket WiFi rental, is not worth all the effort registering your phone at each hotspot hoping that it will work.
Don’t think that none of the WiFi hotspots work for tourists.
There’re free WiFi hotspots you can use, certainly those in hotels and restaurants, but you shouldn’t be blindsided by these huge numbers.

South Korea SIM cards – The top choices
KT Olleh and SK Telecom offer Korea travel SIM’s.
On top of that, a bunch of other providers have their own travel SIM’s that also work in South Korea and that can be picked up abroad.
Further down in this article we list all the SIM cards that we could find along with all the information you need such as the included data plan and the fair usage policy.
In this section, we share our top choices. These are the best data-only SIM’s and the best SIM that support voice calls and text messages.
For short stays
This KT Olleh card offered by Klook is the best for all stays of 30 days or less where a data connection is all you need.
The SIM comes with unlimited data and has no fair usage policy.

For longer stays
Most SIM cards have a maximum duration of 30 days. If you want to stay in Korea for longer than 30 days you will either need to buy multiple SIM’s, something that not all providers allow, or you can use this SIM from KT Olleh which can be used up to 90 days.

Check prices and availability:
KT Olleh long-term SIM
For voice calls
All the SIM cards we cover in this article will allow calls with Skype or other similar tools but in some instances, it is still better to make a traditional phone call.
To do so you will need to buy one of the KT Olleh SIM’s that support voice+text.
These SIM’s can be pre-ordered through Klook and Trazy.
When pre-ordered through Klook the SIM will have a starting balance of KRW 11,000.
The SIM’s pre-ordered through Trazy will need to be topped-up before they can be used to make calls or send texts.
For a duration of 5 or 10 days, it’s cheaper to pre-order with Klook, for a duration of 30-days, it’s cheaper to pre-order with Trazy.



Pocket WiFi or data SIM Korea – what is best
Both are perfect options to stay connected.
During our past journeys, we used both.
A WiFi device might be somewhat easier because all you need to do is turn it on and connect to the broadcasted WiFi signal. It is, of course, an extra device to drag along.
Below are some pros and cons of each.
Pocket WiFi for Korea
The main reason to opt for a pocket WiFi device would be that you don’t need to switch SIM’s and you don’t need to change any settings on your phone. You just need to make sure that your data connection is disabled to avoid any nasty data roaming fees.
This is great if you’re not really tech-savvy and another advantage is that friends, family, work relations and anybody else who has your phone number will be able to reach you as if you were home.

The moment that you install the local tourist SIM in your phone people will no longer be able to reach you on your home carrier’s number. This may be a blessing, it’s time for a vacation after all.
If you don’t mind cutting the ties with the home front for the duration of your holiday then a SIM card is by far still the most convenient option if you’re traveling solo or if you will not be sharing the connection with anyone else.
Everybody will still be able to contact you on Skype, as well as other similar tools such as Google Hangouts, or if you prefer you can opt for a SIM which supports voice+data.

Below is an overview of the different South Korean tourist SIM cards. We included all the important details to help you choose the one that best suits your needs.

Network providers in South Korea
South Korea has the fastest 4G network in the world. Regardless of which network you use, you will surf at speeds that you probably can only dream of at home.
The three mobile operators in South Korea are LG U+, SK Telecom, and KT. They all have an excellent coverage of the country. LG U+ is the winner with a coverage of 99,5% but both other operators also achieve a coverage of at least 95%.
The average download speed is a whopping 40 Mbps, SK Telecom even achieves 65 Mbps. Upload speeds are lightning fast as well.
You will enjoy at least 10 Mbps with peaks to 15 Mbps with the networks of SK Telecom and LG U+.

What you need to know and check before buying a Korean travel SIM
When you rent a Korean Pocket WiFi device you can be sure that it works. Before you buy a travel SIM you better check a few things to avoid some nasty surprises.
Here’s a checklist of the things to check before placing your order.
What you need to know before buying a SIM card for South Korea
Make sure to check these 3 things about your phone.
Googling “technical specs X” where you replace X with the model of your phone should tell you everything you need to know.
Which size of SIM card you need
Over the years the size of the SIM cards has decreased. Old models had the standard SIM, newer phones use the Micro-SIM and the Nano-SIM.

You can’t do anything wrong with these multi-size SIM’s but if the operator only offers Nano SIM’s (like some do) you better check in advance if this is the right size for your phone.

Is your phone unlocked
Locked phones will not work in South Korea, they come with software that prevents them from being used on another network.
If your phone is locked you might be able to unlock it by calling your phone carrier.

Does your phone or pocket WiFi device works in Korea
If your phone is not compatible with the country’s network it will not work.
These are the network frequencies used by SK Telecom and KT Olleh, the two providers which offer tourist SIM cards in South Korea:
- 4G LTE Bands: Band 1(2100MHz), Band 3(1800MHz), Band 5(850MHz), Band 8(900MHz)
- 3G Bands: HSDPA 2100MHz/HSDPA+


What to check before buying a South Korean SIM Card
There are of course important differences between the different SIM cards. Here we indicate what to look for when choosing your Korean SIM card.
Data or Data + Voice
Data-only SIM cards are by far the most common flavor among the tourist SIM cards.
For most visitors, this type of SIM will be all they need. You can’t make any voice calls, and you cannot send text messages either, but you can still call and text using Skype, Whatsapp, Google Hangouts and other similar apps.

Duration
All prepaid SIM cards can be used for a certain number of days. This period starts when you activate the SIM and in most cases, it cannot be extended.

Data allowance
Many SIM cards offer unlimited data but the fair usage policy varies wildly among the different providers. A fair usage policy means that the speed will be throttled after a certain amount of data is used in a certain period of time, usually over the course of a day.
Some providers will cap the speed after 2 or 3 GB is used in one day. This is, in our experience, relatively generous. 3GB is the equivalent of browsing the internet for 36 hours, streaming 600 songs or watching 6 hours of standard definition video.
Others only allow 500 MB of high-speed data per day. This is sufficient if you will only occasionally connect to the internet but you will quickly reach the limits of this subscription if you stream audio, video or often check your social media canals.
Once you reach the data limit the speed is reduced to either 3G or 2G. A speed that may be workable to check some basic webpages but frustrating low if you’re used to 4G.

In our below overview you can see all the details about the fair usage policy and if the card can be topped-up we also mention this.
Pick up
Some SIM cards are shipped (for free) but most SIM’s need to be collected at the airport.
- Make sure to take a note of the location as well as the opening hours.
- In some cases, the order page or the confirmation mail includes a small map that shows where to pick-up your SIM. As you will not have internet until after you have collected your SIM it is a good idea to print this map or you could store it locally on your phone.
- Not all collection points are open 24/7. Make sure to check if the location will be open at the time you arrive and bear in mind that you will need to pass migration. It’s also best to provide a little margin in case your flight ends up being delayed.

Preorder your Korea SIM card online
Here’s an overview of the different prepaid Korean SIM cards you can preorder online. The overview is organized by provider.
For each, we list the most important details, if you need more information you can click on the associated links.
The advantage of ordering your Korean SIM card in advance
If you have just come from a long-haul flight, you are probably drowsy and not in the best shape to make a decision about which SIM you need.
For this reason, we advise you to pre-order your South Korea SIM card online and have it sent to your home address or ready for pick-up at the airport.
Another advantage of ordering online is that you can take all the time you need to compare the different options.

Buying a SIM card in Korea
Your options are limited if you’re already in South Korea when you’re reading this but it is still possible to get a local SIM.
You will either need to head back to an airport or you can visit the KT center near Hongik University Station in Seoul.
At the airport
It’s a bit unfortunate, but unless you’re still in Seoul, the only way to buy a SIM is to go back to the airport. You can buy your SIM there but in most cases, pre-ordering using one of the links above will be cheaper.
In Seoul
To be honest, we were surprised by how few options there are to get a SIM card as a foreigner. Except for the airports the only place you can go to is the KT Center in downtown Seoul near the Hongik University Station.
The office is about a 3 minutes walk from the subway station (take exit 5). It’s open daily from 9 AM until 6 PM.
This is the address: Link Korea, 2F, Floren B/D, 176-8 Donggyo-dong, Mapo-gu, Seoul, Korea
You can head to the office and buy your SIM card on the spot or you can pre-order it online which will grant you a small discount.
Conclusion
We used one of the KT Olleh SIM’s in Korea and it turned out to be invaluable. We used Naver maps during our road trip as well as many other local apps. The connection was always stable and very fast.
Previously, when there were no tourist SIM cards, we managed to discover a country without them, but since the introduction of these SIM’s it has become much easier to discover off-the-beaten-path locations.
It helps to travel deeper and get a better, less touristy experience of South Korea.
All information is accurate at the time of writing (June 2021).
We will regularly update this article but if you notice any changes we would appreciate it if you let us know so we can update our post.
Enjoy South Korea!
