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 SIM card connected without any problems and worked well, although it seemed to take a little longer to load than I'd like. Overall, I'm happy with everything.

At a stadium with a capacity of 50,000 people, communication became impossible around the venue. This is unavoidable, I suppose 😨. On the way back, I couldn't use LINE or map apps, and it took a while for my SIM to stabilize its connection. There's nothing wrong with the eSIM itself; I had very smooth communication on the subway, in the city, and at the hotel 👍.

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)

Perfect for people coming to China. Easy to use, convenient, connects to the internet and works fine, not too slow.
