Getting a prepaid SIM card for iPhone 5S in South Korea?

I'm doing a student exchange in South Korea this summer, and I'm not sure how to go about getting a SIM card? Are they generally pay-as-you-go? Or can I prepay for a set amount of data and airtime?

Yes, there are prepaid services and contracts too. If you need iPhone 5S factory unlocked cheaper than retail, mail me.

  • USA to South Korea text.Will he get my text message? I have an iPhone and he has a Samsung. I sent a message to him and the message is green. How do I know if he received the message? South Korea numbers start with +82 10 USA numbers start with +1
  • Iphone 5S on 02 will it work in South Korea? I'm off to South Korea will my iphone 5S work there? I'm on 02? I have heard rumours they don't have the same frequency. I will be turning off my data roaming and 3G/4G as I don't want to be charged a fortune on my return. Any ideas?
  • How would I get an iphone 3gs to work in south korea? I live in the states right now but i will begin visiting korea for long periods of time soon. I want to get a phone over there. I currently have an iphone, as do most of my friends. I want an iphone with imessage so i can talk to them, and i kind of want a 3gs as it does everything i want. How can i make one work overseas but without a plan, like just call and texting? What kind should i get, like will just a regular unlocked one work?
  • Going to Korea soon, need a pay as you go SIM card? I'm in the States right now. I have a Verizon iPhone 6 so it works with most carriers. I need a plan that has a few texts and maybe 10 minutes of call. I will only be gone for a week and don't plan on texting (maybe 20-30 at most) much nor using the phone to call. I just need a phone to respond to some texts and make a call when I get back to the States. Where can I get this pay as you go plan that would work for me?
