Itโs hard to imagine traveling in a foreign country without the internet these days. Although South Korea provides free internet services in public places, you will definitely need to access the internet during your trip. However, finding the best SIM card or WiFi is not easy. Comparing the options of SIM cards and WiFi is an almost impossible mission for ordinary people.
Fortunately, I worked for a telecommunication company in South Korea for a long time. So I did your homework for you. I investigated all the SIM card, WiFi, and eSIM product options of multiple service providers.
Some companies say they provide unlimited 4G internet access. However, the products provide 128kbps, which is almost unusable in this multimedia world after the data of the 4G speed is used up. Staying connected during your travel to Korea shouldnโt have to be complicated. Here are the best ways to do so.
So I compiled and compared prices and options of SIM, eSIM, and Wifi products for your trip to South Korea. It took over a week to make this spreadsheet. You can easily find your perfect-fit product at the best price. Check it out!

Here are the best SIM / eSIM / WiFi services in the most common cases. Letโs jump into the result of my research!

Which is better, SIM or Pocket WiFi?
To determine which is best for you, think about your answers for the below questions:
1. How many people in your group will be connected to the internet?
2. How long is your trip?
3. Are you guys keep sticking around together during your trip?
You can use your SIM card on a phone but people can connect up to 3 devices on the same pocket WiFi. (Service providers say up to 5 people can connect, but if you try it, you will understand why I say you can connect up to 3 people.) Using a SIM card is easy and private. You donโt need to return it. They also give a discount for every additional day you buy.
A Pocket WiFi is good for two or three people and is also cheaper than a SIM card. However, you always have to bring it with you and recharge it regularly. You also need to return it when you leave. They provide a huge discount from the 6th day.
Hopefully, this information has helped you determine what works best for your trip!

If you have recent smartphones, you donโt need to buy a hardware SIM card. An eSIM is a software SIM card that can be embedded in your smartphone.
You can easily purchase software eSIM online. Needless to say, you donโt have to struggle to find a SIM pick-up area at the airport. Just search your destination, select the data plan you want, and add the eSIM to your smartphone.
Things to know before you buy eSIM
I extolled the virtues of eSIM. However, there are still some limitations to using it.
- Please, make sure if your device is eSIM supported and unlocked
- Prepaid eSIMย doesnโt provide a phone number. Itโs aย data-only plan.
- You may see the Unlimited Data Plan. Itโs literally โUnlimitedโ, but there is a certain high-speed data usage limit. When you exceed the limit, you will be limited to a lower speed rate.
- Itโs not refundable.
Moreover, they support regional SIM as well so that you can use it in many different countries in the same region. Check your smartphone supports eSIM HERE!
