Reviews: South Korea 5G eSIM | TikTok & ChatGPT Available | Day Pass/Total Data Package | 24-Hour Billing | 1-30 Days | QR Code
Guest User2026-04-04
The signal and network speed are both great. I don't know how those negative reviews came about. I'm using an iPhone 17 Pro with this eSIM and the experience is excellent, including in Seoul. I also went to Busan and the signal was still great. The key is the affordable price. I'll definitely buy this again next time I go to Korea.★

The signal is excellent, no weak signals. Easy to buy and install in Thailand. The signal really starts to pick up once you arrive in Korea. It can be configured to receive OTPs, which is convenient and doesn't require worrying about extra charges. The only downside is that TikTok is blocked, which is a bit annoying, but at least I can't use it much, haha.★

Trip.com didn't really show up when I was searching for an e-sim, but I'm glad I found it. Works just as well as any other e-sim, for the fraction of the price.★

Very convenient eSIM service! Everything was set up quickly and smoothly through Trip.com. I had a small issue, but support responded right away, the bot guided me step by step and resolved it fast. Definitely recommend!
