After I got my ID, i went to a provider office for buying a sim card. There are 3 providers in korea, SKT, KT, & LG U+. I chose one nearest my house, SKT headquater office in Sinchon. For you foreigner, you have to bring your local ID. Because here in korea, you can only have one telephone number, not like in indonesia buy IDR 5000 sim card then you can buy other.
1. Take a service number
2. Show your ID and pick your number
Here you have to pay ₩25000, for a sim card, and you can choose 4 last number as you want! Me chose my birthday hihi. And after that you have to use your package.
Mine is ₩38,500/ month
include unlimited call for SKT number, 100 minutes call to other provider, unlimited text to all providers, and 1.5GB internet package.
The staff said, if you already have a bank account, your monthly bill will directly debit. But for me, i still dont have a bank account, i have to come to SKT office to pay my monthly bill, if i'm late, SKT will cut the service until i paid it
If you make a new sim card, you'll get a membership, can get some discount in some stores, like paris baguette, angel in us and many more ~
The officer can't speak english well but i still can understand a little, thanks 이부미 님 for your help
