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

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

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

11 simkorea.blog has brought me here.The information there was awesome.I recommend you all to refer the site.Korea sim blue was enough for my trip. Rachael 2018-03-05 81 5points

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.
