I wish I had tried it sooner. I wasted money on other, much more expensive eSims with data limits. Trip.com's products are excellent.★

I used it on a business trip. The hotel Wi-Fi was sometimes unreliable, so I ended up using the eSIM the whole time.
In Korea, too, smartphones are increasingly becoming essential, so I think an eSIM is a must.
I don't like carrying a separate Wi-Fi router.
I will use it again.★

Reviews: South Korea SKT 5G/4G native eSIM | calls + SMS | 010 phone number | 24 hr billing | QR code
Guest User2026-09-07
I used this service for a 3-night, 4-day trip to South Korea. It was my first time in Korea, but it was incredibly convenient, and I had no problems with internet access during my trip. I didn't use the phone function, but having a phone number associated with it gave me peace of mind in case of any issues. I would definitely use it again when I go to Korea.★

Reviews: South Korea SKT Native 5G/4G eSIM | Including Phone Number + SMS | Supports Google Maps / TikTok / ChatGPT | 24-Hour Billing | 1-90 Days | QR code
Guest User2026-10-18
Highly recommended! I used this SKT native eSIM throughout my trip to Korea, and the signal was excellent with no dead zones whatsoever. Best of all, it comes with a local Korean phone number and SMS functionality, which is incredibly useful for things like waiting in line at restaurants or calling a taxi. The 24-hour billing is also very flexible. I'll definitely buy it again next time I'm in Korea!★

Reviews: South Korea SKT eSIM | 5G or 4G 100GB Data | Voice & Texts | ChatGPT Full Access | QR code
Guest User2026-09-28
My experience ordering a Korean eSIM from Trip.com was fantastic! I received the QR code quickly after ordering, and the setup was incredibly simple – just scan the code and it was done in seconds. As soon as I landed in Korea, I was connected to the signal immediately, and the 5G speed was fast and stable throughout. Whether checking maps, posting on Instagram, or checking in, everything was smooth and lag-free, eliminating the hassle of switching to a physical SIM card. The price was great, and the service was flexible; I'll definitely buy it again next time I travel abroad!
