Korean Sim Cards: Essential Info

Korean Sim Cards

Korean sim cards are the best option to use your phone to its fullest when traveling in Korea. This will give you the same services and functionality as if you were in your own country and allow you to make and receive calls, send text messages, and use data-based services such as surfing the Internet, streaming, and updating social media.

If you need to have a connection to the world 24/7 or want to share updates with friends and family as you travel, a Korean sim card is probably the best option for you.

In order to use a Korean sim card, you should make sure that your phone meets the following requirements:

  • Your phone is a WCDMA device (3G and newer).
  • Your phone is unlocked and can accept a new sim card.
  • You haven’t used another Korean sim card recently.
  • You can use a normal | nano | micro sim card.

As long as your phone is unlocked and at least 3G compatible, it should be fine to use a Korean sim card in your phone when you travel to Korea. Not sure if your phone is unlocked? Contact your cellular company or visit this website to check.

If you’ve never used your phone in another country, it might be worth contacting the Korean sim card vendor to check compatibility for your phone’s model and IMEI number.


Requirements To Buy A Korean Sim Card

Here are some of the most common requirements to buy a Korean sim card online or in Korea. If you buy the sim card online (recommended), there may be additional requirements when you collect and activate the sim card in Korea.

  • Passport
  • Contact details
  • Address (in Korea)
  • IMEI number of your phone.

Korean phone accounts are used as a form of identity in Korea and, even if you’re using it as a tourist, it is still necessary to provide identification to use the sim card.

Pre-ordering and collecting a Korean sim card at Incheon Airport is the best option for travelers for two main reasons. Firstly, travelers arriving at Incheon Airport will have their passport with them. Secondly, staff at Incheon Airport’s collection desks are used to dealing with travelers in English and can set up and check the sim card immediately.


Advantages Of Korean Sim Cards

There are several reasons why you might want to purchase a Korean sim card when you travel to Korea. The benefits of having a Korean phone number have increased in recent years as mobile services grow and travel restrictions have required contact numbers when traveling. Below is a summary of the key advantages of getting a Korean sim card.

Korean Phone Number

The biggest advantage of having a sim card is the ability to get a Korean phone number, which opens up a world of apps and services that aren’t available to other travelers. The biggest uses of a Korean phone number are for mobile apps such as Coupang Eats (food delivery) and Kakao Taxi (taxi service), as well as the ability to make online bookings and reservations in Korea.

If you want to book tickets for a concert or attractions like the Haeundae Sky Capsule, you need a Korean phone number to complete the reservation. When you buy a Korean sim card, make sure that the sim comes with a phone number – some data-only cards don’t.

Always Connected

Korea’s network coverage is amazing and you’ll almost never find yourself without an internet connection, even if you’re climbing up a mountain or walking in the countryside. Having a Korean sim card gives you full access to Korea’s wide phone network.

Less To Carry

A sim card easily slips into your phone and weighs almost nothing. Portable WiFi routers aren’t heavy, and most can be tucked into a bag or purse, but they do need to be carried as well as your phone.


Disadvantages Of Korean Sim Cards

Although sim cards are the most convenient and useful option when traveling in Korea, they do also have some downsides when compared to Portable WiFi routers. Here are a few of the most common problems with sim cards, including one that might surprise you.

Fixed Usage Period

When you order a Korean sim card, they’re typically fixed for a certain amount of time. For example, 1 day cards, 3 day cards, 5 day cards, etc. This is fine if you’re traveling in Korea for a time that matches those fixed periods, but it can often leave you paying more if you’re traveling outside those times.

Travelers who need a sim card for 8 days may find themselves having to choose between a 7 day card and a 10 day card. Pay more for 8 days of coverage, or lose a day and go for the 7 day card. Portable WiFi routers are charged per day, so you always pay for what you use.

Fortunately, sim cards can be extended beyond their original time limit by contacting the service provider, which is a good option if you plan to stay in Korea for a reasonably long amount of time.

Limited To 90 Days

Travelers can only use Korean sim cards for a maximum of 90 days. This won’t be an issue for most travelers who visit for a week or two, but could be a problem for students studying for 3 to 4 months at a time. As mentioned, you can extend your Korean sim card from its original time limit, but only to a maximum of 90 days. It can only be extended beyond this if you have an Alien Registration Card (for long term residents).

Hard To Use Another Sim

Again, this isn’t a problem most travelers will face, but it’s something to consider if you’re planning to visit Korea often or stay in the country. Once you’ve signed up for a sim card, you’re tied to that company and sim and you might be blocked from signing up for another sim soon after. This is mostly due to Korean security laws.

Camera Shutter Noise

In Korea, all phones must make a shutter sound when using the camera, including screen shots. This is due to laws to prevent unwanted photography and people taking secret pictures with their phone. When you use a Korean sim card, your phone settings will automatically be changed to turn on the camera shutter sound. You can’t change this while you’re using the sim card. Once you leave Korea and change your sim, the camera sound will go back to normal.


Always Read The Fine Print

When buying a Korean sim card online, be sure to check whether or not the sim card will do everything you want it to. Some data-only sim cards give you just that – data. They won’t provide a Korean phone number, which is one of the main reasons for getting a sim card in the first place.

Also check whether or not the sim comes with any credit, or if this needs to be purchase on top of the cost of the sim. Are there additional costs for going over your data limit or daily limits on how much you can use?

The sim cards recommended below are all traveler-friendly and come with a Korean phone, all-inclusive data services, and are from reputable companies that have provided safe and reliable phone services in Korea for years.


What About Korean E-Sims?

An alternative type of sim is the eSim – an electronic sim card that is stored on your phone like an app and doesn’t involve changing your sim card. You can download these to your phone and switch between your regular and Korean phone services. Although these have been popular in other countries for a few years, Korea only started to embrace them since summer 2022 (due to pushback from Korean phone companies).

Korean eSims can be a convenient option for travelers with newer models, but if your phone is more than a few years old, it might not be compatible. Also, some eSims don’t come with a Korean phone number, negating one of the big advantages of getting a Korean sim card.

You can buy Korean eSims online from Klook and other companies operating in Korea.

Buying Korean Sim Cards In The USA

If you want to make sure a Korean sim card works in your phone before you travel to Korea, you could order a Korean sim card from Amazon. The benefit of ordering a sim card from the USA is that you can register and activate (with certain cards) your sim card before you travel. That means there are no complications when you arrive in Korea. To see what sim cards are available in the USA, click the link below.



However, there are some down sides to ordering a Korean sim card in the USA before you travel. As with any sim card you buy, you should check to make sure the sim card is compatible with your phone before you order it. Returns may not be possible once opened.

The total price of the sim card and phone services is likely to be higher than you pay when you buy online from a company operating in Korea like Klook or Trazy. Also be sure to check that all the services you want (Korean phone number, data, calls, etc.) are available.


Korean Portable WiFi Routers: Essential Info

Korean Portable WiFi Routers

Portable WiFi routers are a family and group-friendly option for connecting to the Internet when traveling in Korea. One mobile WiFi router can be used to connect multiple devices without the need for a sim card.

Portable WiFi routers connect to mobile services provided by Korea’s 3 phone networks and essentially work the same as a sim card without the need to plug it into your phone. You get the same secure connection and wide network coverage, too.

Portable WiFi routers can be purchased on a day-by-day basis, which is a big advantage over Korean sim cards which have fixed time limits. As long as you declare which days you’ll book the router from, you will pay the same daily fee.

If you want to hire the router for extra days, you can simply pay for the extra usage when you return the router. There may be a higher daily cost for using the router longer than originally declared.

Please note: Even if you only use a portable WiFi router for half a day, it will still count as a full day’s rental.


Requirements To Rent A Portable WiFi Router

To rent a Korean portable WiFi router, you will need to have a valid credit card. Here are details about credit card requirements.

  • More than 3 months validity remaining
  • Visa or Mastercard only
  • Must use the same card to book and collect.
  • Must be in the same name as the person booking and collecting
  • Debit cards are not accepted.

Basically, make sure you book the portable WiFi router in your own name and with your own card. Bring that credit card with you when you travel to Korea and present it when you collect the router. Some conditions may be different depending on which company you rent your WiFi router with, but these are the most common rules.

The credit card will be used to secure the deposit on the router in case it gets lost or damaged. You will be charged any extra usage costs if you went over your agreed time limit when you return the router at the end of your journey.


Advantages of Portable WiFi Routers

There are several reasons why you might want to purchase a Korean portable WiFi router when you travel to Korea. The benefits of being able to connect multiple devices for one fixed cost and at a lower initial cost than a sim card makes it ideal for short-term travelers.

Can Share With Other People

Portable WiFi routers can connect up to 3 devices simultaneously, which is perfect for families or travelers with multiple electronic devices, such as a phone, tablet, and laptop. There is no restriction on which devices are connected, as long as there are only 3 at one time. You can connect mobile phones during the day as you travel, then tablets at night when you want to relax or work in the hotel.

Lower Daily Cost For Short-Term Travel

Portable WiFi routers are cheaper per day for short-term travel than sim cards. The daily cost of a portable WiFi router is around 3,300 KRW per day, whereas a 1 day sim card costs 5,900 KRW and 5 day sim cards are just under 5,000 KRW per day.

If you’re traveling in Korea for 10 days or less, a portable WiFi router will cost less than a sim card. When you consider that up to 3 people can connect their devices to one router, it’s even cheaper per person.

Easy To Extend Usage Time

The rental plans on portable WiFi routers are flexible so if you need to use it for longer than you expected, you can keep using it and pay for the extra rental time at the end. This is useful if you change flights, get delayed, or don’t want to commit to renting the router for a long period when you first arrive.


Disadvantages Of Portable WiFi Routers

Portable WiFi routers are cheaper and more flexible than Korean sim cards, but there are also some disadvantages of using these devices, such as additional weight and charging requirements for the extra device. You also won’t get a Korean number.

No Korean Phone Number

The biggest disadvantage of portable WiFi routers is that they don’t come with a Korean phone number. That means you can’t use features in some Korean apps, make online bookings within Korea, and can’t call or send texts. Of course, there are alternatives for calling, such as using messaging apps.

Requires Carrying & Charging An Additional Device

Portable WiFi routers aren’t that heavy, but they certainly add to the weight you need to carry each day if you want Internet access as you move around. They’re certainly heavier than sim cards. There’s also the need to charge them, as well as the other devices you want to connect them to. This isn’t a big issue as most good hotels in Seoul will provide plenty of sockets to charge your devices.

Remember, you’ll need a Type F plug adapter for Korea. Fortunately, some WiFi rental companies will include a charger for the router that can also be used for certain phone models, reducing the number of travel adaptors you need.

Everyone Using The Router Must Be Nearby

While connecting to 3 devices with a portable WiFi router is easy and provides a reliable Internet connection to those users, they will all need to be nearby. This isn’t a problem if one person is using the router for multiple devices, but can be an issue for families traveling in Korea who might split up and do different activities, such as exploring Lotte World Theme Park or walking around Nami Island.
