Why Clients Love Us
NeoKoSIM has been my go to service since I found them in 2016. They have always been friendly and efficient, and offer so many choices for those travelling to Korea.
Highly recommend to everyone needing a phone/data service while in Korea. Thank you always!
Even during the COVID-19 situation in 2022, I was extremely satisfied with the service, and I’m still very satisfied as of May 2023. The service itself is excellent and I was able to check all the setup in advance via KakaoTalk or email with the owner while still in the U.S. If any issues arise after arriving in Korea, the owner’s support is highly professional and prompt. I highly recommend this service!
Thank you for your quick and kind service.
I always choose NeokoSim when visiting Korea, as it provides reliable connectivity and excellent service every time.
I’m very satisfied and will certainly purchase again on my next visit. Thanks again! 💗
