Summer, 2023
It is the same with every foreign country, but when traveling through Korea, smartphone internet is one of the top 3 necessary travel arrangements along with airline tickets and lodging. In the present 2023, when considering many factors, the best eSIM product while traveling through Korea is the Korea eSIM Red from SK Telecom, the number 1 mobile carrier of Korea, which provides unlimited data service. Below are the 8 reasons why. If you have any questions, or disagreements we welcome feedback. This will be updated in our later versions.
1. There is no decrease in data speed.
Most mobile telecommunication services decrease internet speed when you use a lot of data. For instance, even if you have unlimited data when over 1GB is used in a day the speed noticeably decreases. However, Korea eSIM Red has no speed decrease regardless of usage. Along Korea’s top 3 mobile carrier companies SK Telecom, KT, and LG Uplus, only SK Telecom is providing this service through Korea eSIM Red. Of course, data sharing and tethering are also possible.
2. You can finish setting and scanning before your departure.
If you order your eSIM product, you will receive an eSIM QR code through email. So, when should you scan this and use the settings? Then, you wonder. “Can’t I just safely scan and set this up now at home? If I scan this in Korea, and the settings don’t work, it’ll be a hassle.”
To be brief, if you use Korea eSIM Red you can scan and use settings before departing to Korea whenever you want. If you scan and find the words ‘activating…’ in settings, you can boot your cell phone and use it right away in Korea. Of course, the time of usage also starts from the moment you turn on your phone in Korea.
3. There is no fear of failing setup.
If your eSIM settings don’t successfully work, you can visit the SK Telecom booth in Korea, located in every airport, and worst-case scenario, they will change your product to USIM and help with settings. SK Telecom is the only mobile carrier that has booths at every airport in Korea. (For instance in Jeju International Airport SK Telecom is the only carrier booth that you’ll find.)
4. You can use your use time efficiently for longer.
The time of use counts not by days but by hours, so you can use the service for the longest interpretable time. For example, a 5-day product activated on August 3rd, 10 PM can be used until August 8th, 10 PM. For other eSIM products, most of their usage time is shortened by the day. Therefore, if the product is activated at 10 PM, a day is spent just after 2 hours of use.
5. It can receive calls and messages through the 010 Korean mobile number.
In many cases of prepaid eSIMs, service is provided only through data and does not provide a mobile number, or provides a 012 number. However, the actual mobile number that Koreans use is 010. Korea eSIM Red provides a 010 number, and you can use unlimited free incoming calls and messages. For now, only receive-only and data-only services were provided, but after August 2023 you can upgrade your eSIM service to able outgoing calls and messages after visiting the airport carrier booth.
6. There is no procedure where you have to provide or register additional personal information.
When using Korea eSIM Red you do not need to provide or register any other personal information except your email address, used when sending you your QR code after purchase. After you receive the QR code by mail, you can scan and set it up, then activate and use the service whenever you want without any additional online activation process.
7. It has the cheapest price.
The 3 local Korean mobile carrier companies (SKT, KT, LG Uplus) have almost the same eSIM price per period. KT and LG UPlus occasionally have events that sell their products with a 10% discount in case of online pre-order. However, at Korea SIM (krsim.net), the official partner of SK Telecom, you can buy Korea eSIM Red always with over 21% discount, and buy eSIM at the cheapest price among the three.
8. You can get quick customer service.
Among the three local mobile carrier companies in Korea, SK Telecom is the only carrier company that has 24-hour customer service providing languages such as English, Japanese, and Chinese. Having an agency that can help solve your problem when it occurs is surely a great advantage.
