Reviews: South Korea 5G eSIM | TikTok & ChatGPT Available | Day Pass/Total Data Package | 24-Hour Billing | 1-30 Days | QR Code

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.

I used this for a solo trip to South Korea. It was my first time using an eSIM, so I didn't understand the initial setup and used the chat support service, but after setting it up, it connected everywhere and was incredibly convenient. It was also much cheaper than other eSIMs, which was great. I would definitely use it again!

Very convenient and easy installation; activated immediately upon arrival. I had good connection in Seoul and Busan. We had no internet issues throughout the entire trip. I highly recommend it!

Easy to install and use on my samsung device. Signal is pretty well around Seoul & Suwon area. Worth the purchase.

I went to Yeongdo, near the airport in Busan, and the signal was extremely fast and never dropped. Wi-Fi and other services are always too slow and uncomfortable. For a solo traveler like me, this was like a fish in water, making the trip much smoother! Translation and map navigation were instant and fast, the routes included phone numbers, and location services and ordering food delivery couldn't be more convenient! Not having to change SIM cards is a huge plus. Highly recommended! (Based on my iPhone 17 Pro for reference)

It's very easy to set up, and in case of emergency, the support team responds quickly. We stopped the data plan because it was difficult to track how much we were spending. We thought we were low, but it turned out we'd used it all. That was probably the only annoying issue. But that was with our previous SIM card; this time, we've learned how to monitor it via mobile data and set daily limits. We recommend it.
