It suddenly didn't work as soon as I used it.

I was so embarrassed that I asked for help in a Facebook message.

He asked me if I had done activation...!

Then I did STEP 3 as per the manual :)

Luckily, it was used right away 5555555

Thank you for helping me

Outstanding customer service. I was in the city and couldn’t get prepaid SIM from KT shop near Gangnam station. In desperation I got WiFi at nearby restaurant and found this place. I messaged them via FB messenger and got reply almost immediately (earlier today 8:30pm Korea time). The customer service rep went out of his/her way (couldn’t tell) to help me even sending me the exact location of the mini mart that sell the Prepaid SIM. The CS rep even called the mini mart to check if they have the SIM in stock! Seriously outstanding service. This CS rep solved the problem in 10 minutes what incompetent staff at said KT shop couldn’t in one hour

Great SIM and value. 10GB of unthrottled data (data can still be used after) for 15 days. To extend, just use the app and pay an extra fee.  It was the only Sim I could find that allowed top-up and had a 15 day option (instead of 10 and 30) so this was a no brainer. There's also free access to KT wifi via KR SIM customer service, which is a Lifesaver when you exceed the 10GB and want to watch videos on long train rides! Re VOIP calls, FB calls work.

The counsellor on Facebook messenger is always ready to answer. Unbelievable. That is so impressive.

Mobile internet service quality is second to none. outstanding! Never experienced anywhere.

Logan White 2018-04-09 16 5points

The best sim as far I know. Ive never found more attractive South Korea prepaid SIM than this. Recommended.

Michel 2018-04-09 35 5points

Korea Sim went above and beyond to help me during my trip. I had purchased a Blue LTE sim which for some reason would only connected to 3G. After various failed attempts to connect to the LTE network, I was content with using the 3G network for the rest of my trip but was told by staff that I paid for LTE and deserves to use LTE. They went out of their way to reset the values for me and by day two I was on the LTE network! Definitely recommended!

외국에서 친구 올 때마다 하나씩 선물합니다. 전화번호, 통화도 할 수 있어서 한국 내에서 꼭 붙어 있을 필요도 없이 서로 연락하기 딱입니다. 데이터 속도에 감탄들 합니다. ㅋㅋㅋ

혜영 2018-03-19 45 5points

I always use this SIM my travel in Korea.You can find this usim at Myeongdong or Hongdae convenience stores.But it's much cheaper to buy it onlineDon't be nervous. If I did not receive it at the airport, they said they would send it to the hotel.But I received it at the airport.It's so easy to find a pick-up desk.I applaud this SIM card

Jordan 2018-03-16 59 5points

I tried to activate the SIM by online at '4AM'. And it was done immediately!! It must be an automatic process.

I was really worried before the purchase.

Blue card is because international calls are impossible.

But if you connect to Wi-Fi, you can use skype.

This is enough :)b

And I have no regrets.

It was easy to find the booth for the simcard. The internet was fast and the signal was good, even in areas outside Seoul. Will buy again when I go to Korea soon.
