Update: check out our 2018 Guide to Korea Prepaid SIM Cards and Wifi Routers, updated May 2018
Most everyone flies into Seoul Incheon (ICN) airport when visiting Korea. I gathered some prepaid SIM card info for you all so you can stay connected while visiting South Korea. It’s pretty straightforward though you might need to wait in line to buy one. The counters were very busy while I went.
Prices are not cheap. Aside from getting the card at the airport, you can get a 7 day 3 GB data SIM card mailed to you before you go to Korea from HKSIMCard. It’s a little cheaper than buying at the airport in Korea.
- kt is the only company there offering prepaid SIM in the arrival hall.
- lg offers mobile wifi routers and phones, but no SIM cards.
kt offers a few different options; SIM card, wifi router egg, and phone. Won’t be covering phones here, if you need one check the kt site.
Prepaid SIM (voice support) or Data only Prepaid SIM details are as follow:
|Kinds||Period of use|
The rates are a bit high in my opinion from kt. You can also get a sim card mailed to you, so you have it when you land in Korea, from HKSIMCard. 3GB of 4G data SIM card, valid for 7 days for $26.95 US.
|Data Rates||Charges to Receive|
|Charges for Making|
I recommend the data prepaid SIM. It’s unlimited data, and if you need to make voice calls you can simply use Skype, WhatsApp, or another data based voip program. Then you won’t be charged a separate calling rate. You also don’t need to return the data prepaid SIM.
But if you do want a SIM card that supports voice, rates for calling are:
(※ Vat is included.)
|Charges for Making Calls/Sending Texts||Rates|
|Call||Domestic||264 won/1 min||Charge paid for voice/text services after returning the SIM Card|
I assume you need to leave a credit card if you get a prepaid SIM with voice since they’ll charge you for usage upon card return, bit of a hassle to return the card IMO.
Wifi Egg Router
I don’t like using wifi routers since you can hotspot using any smartphone these days, so basically you’re carrying an extra device around if you choose the router option. You also need to pay a rental fee on top of the usage fee, and return the router after you’re done. Here is the fee breakdown:
|Data Rates||5,500 won /day|
|Rental fee||1-10 days||3,300 won / day|
|11-20 days||2,200 won / day|
|21 days –||1,100 won / day|
Egg lasts about ten hours.
LG only has routers and phone rental. Little cheaper than kt
Daily rental fee: 3000 won/day (if the rental period is 5 days of longer, rental fees are free from 5th day onwards.)
By the way, if you have a long layover, you can get a Seoul free transit tour sponsored by the airport.
