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.

Excellent connection for 15 days. We flew to China with a long layover and then on to Vietnam – we were always connected. The internet was smooth and very fast, no problems at all. Thank you very much!

It was easy to use and worked flawlessly throughout the trip. I could even watch videos or upload videos while traveling on the subway without any interruptions or lag.

Reviews: South Korea SKT 5G/4G native eSIM | calls + SMS | 010 phone number | 24 hr billing | QR code

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.

I've used it before. I especially like that I can use it in multiple regions without any hassle.
