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 eSIM for Traveling in Asia! Absolutely fantastic experience with Trip.com eSIM! The setup was incredibly quick and easy, and the internet connection has been fast, stable, and reliable throughout my travels in Asia. The best part is that Google, WhatsApp, Gmail, YouTube, and all my favorite apps work perfectly, even in China, without any issues! Excellent coverage, great speed, and seamless connectivity. No complicated setup, no interruptions, and no headaches. Highly recommended! A must-have for anyone traveling in Asia. I will definitely use it again on my future trips!

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 5G eSIM | Dual neworks, supports ChatGPT & Google Maps | 500MB/day - 50GB total | 1-30 days | 24-hour billing | QR code

A great option for a trip to Korea; the locals were charging 35,000 won for a monthly SIM card. We got a 20GB plan for 30 days for about 12,000 won, of which we used about 10GB, since there's Wi-Fi in many places. Next time, we'll get a 15GB plan for a month; it's enough for us and even more affordable.

Buying a virtual card is easy. Installing it was a bit confusing at first. We received a few. Just enable roaming on the virtual card and it's up and running. It works well everywhere, even on the subway. 5G. I highly recommend it.
