This was my first time using an eSIM. I was worried about whether I would be able to connect at this price, but I had no trouble getting 5G during my three-day, two-night trip to Korea. I kept using my phone while sightseeing, checking map apps and navigating train routes, and had no issues. It was convenient and I was able to set it up right away at the airport! I'll definitely use it again!

We had some problems with installing the e-sim, but trip.com customer service came to rescue and everything is good and well. Signal is good too.

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!

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 used this in KL, Bangkok and Shanghai. Overall the signal was ok. Sometimes we do get a drop out but it’s not often. We managed to use all social media platforms with this eSIM at Shanghai. Only thing is if you want to hail a ride you’ll need a number for it in china.
