Reviews: South Korea 5G eSIM | Dual Network Coverage | ChatGPT | 1–30 Days | Instant QR
Guest User2026-01-17
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!★

Guest User2026-01-16
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.★

Reviews: [Free T-money] Korea KT 4G/LTE Unlimited Data SIM + 010 Phone number | Korea Airports Pick-Up
Guest User2026-01-09
I always purchase esim with korean number for convenience when either ordering food deliveries or anything items during the period of my stay. Even though i put 5 stars. This is the first time, this phone number i’m assigned to, is getting so many scam and spam calls every other fking minute is something unexpected and it’s frustrating.
