Reliable Mobile Network
Amazing!
Great SIM card. Unlimited data and very fast DATA SIM card ever.
I am very happy with the product and never experience any problem in Seoul and Nami Island. A perfect product providing data and calls. I must also mention the customer service is exceptional in their fast response and providing solutions to my concerns. I will definite use NeoKosim when I am in Korea,
Works very well and total experience so far has been great.
지금까지 한국에서 사용하는 유심 때문에 항상 고민이였는데 정말 좋은 업체를 알게되었습니다. 앞으로 장기 거주지를 위한 다양한 프로그램이 도입되었으면 좋겠습니다.
격려의 말씀, 감사합니다. 노력 중입니다. 계속 지켜봐 주세요.
Clear, straightforward instructions to get connected first thing as you enter Korea. Excellent coverage and speed. Strongly recommended.
Would recommend it to everyone. No other service provider gives all data, calls and text. Would definately use this again for next time
Very good service and connectivity. Pick up at airport was easy.
Amazing quality. I really loved it!! Would love to use it next time again!
This is the first time I’m using Neokosim as recommended by a friend. So far so good. 🙂
I always use Neokosim whenever I visit Korea! I’ve recommended the service to my friends as well, and they love it 🙂 Thank you!
Perfect service.
People from Neokosim were reakky helpful.
I was so pleased to find NeoKosim before my trip to Korea last year.
And I’ve kept using them since.
Their customer service is 2nd to none, as is the product they provide.
Whether via email or in person at their office, they have always been efficient, helpful and very friendly.
Definitely 5 out of 5 in all aspects of their business, service and support.
The service worked at all times whilst I was on the Sth Korean mainland, and also during my trips to Jeju-do.
It never failed me.
Thank you so much!
Thank you so much for your warm heart comment. Have a nice coming trip in Korea!
awesome speeds, easy to find at the arrivals gate in seoul. Best data travel sim experience. Will use again.
I rated this 4.5 stars but actually meant to rate it 5. I bought an unlimited data SIM for one month and it was so good I renewed my subscription.
First of all, as somebody who doesn’t speak Korean, the Neokosim has a very friendly, awesome customer support system and answer emails very quickly. The service you get from start to finish is fantastic, especially if you go to one of their centers and they put the card in for you. They set it up, give you a wallet for your old SIM and it’s really easy.
The product is also incredible. Always has solid service (apart from the last 24 hours of the SIM where the signal became spotty) which can stream without any problems. The SIM also doesn’t ruin your phone so if you use things like kakao and whatsapp, it won’t ask you to renew your credentials.
If you’re in Korea for a week or so, I’d recommend getting the unlimited data SIM. Yes, you can get wifi eggs (I did before I moved here) but the have limits per day and you can lose an egg. You put this SIM in, restart your phone, turn on your data, and then throw the sim away when you’re finished or back home.
Thoroughly recommend!
Neokosim is a great company that always helped me when I need it! Not only for travellers but if you live in korea you can use it too! I use it for almost 11 months and I love it! Great unlimited internet and great staff!
i highly recommend neokosim. The internet is so fast and i didnt have any problems.
Half way through my trip and no problems at all. Used all throughout Seoul and outlying areas like asan. Used on the KTX from Seoul to Busan. I have never once had no service. Am very happy and will be using this service every time I am here in Korea.
This is perfect, great LTE, never let me down, that’s why I use always whenever I visit Korea.
