Easy to use, you need to check your phone whether your phone support e sim or not. It was far cheaper than when u paid for roaming, cheaper ten times more!!★

The service was very simple and easy. It really didn’t disappoint. I relied on the service so much while traveling through Seoul, Busan and Jeju.★

My five-day trip to Seoul was very smooth, and the installation was straightforward even for beginners. Initially, the installation in Taiwan was a bit confusing, but the customer service was excellent and patient. I was worried that it would be almost 11 pm and no one would respond or I would receive a message, but a real person replied, resolving my doubts and anxieties. Highly recommended! 👍★

I used it on my recent trip to Seoul. My husband doesn't use much data while there, so I let him use it for free as part of his membership benefits. It loaded quickly, had good local signal, and was perfectly adequate for a 3-day, 2-night trip.★

I was able to use PayPay even in Korea! Amazing! ⭐︎I installed it according to the instructions after arriving at the airport. I couldn't connect properly, so I contacted customer service through the app and they told me that data roaming wasn't turned on. I quickly turned data roaming on in the settings and it started working again! Customer service lists various ways to contact you, such as email and LINE, but LINE wasn't working, so I think it's best to contact customer service through the app. It was resolved in 2-3 minutes! It's definitely best to resolve this while connected to the airport's Wi-Fi.◎ I went to Myeongdong and there were no problems with the signal. There are very few eSIMs in Korea that accept PayPay. I recommend this!★

Once the eSIM is activated, remember to also activate the data abroad button (settings - cellular data) so that the network works.
