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.

We bought this card for a trip to China and South Korea. It was very convenient to use (no need to activate it multiple times in different countries) and very affordable (it's much cheaper if you buy multiple SIM cards). The connection quality was excellent! Internet was available everywhere and always without interruptions. I highly recommend it!

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.

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.

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