💡 A smartphone with internet access is one of the most important things a traveler needs. For those of you nodding your heads, what should be the first thing you need to do when you arrive at Incheon International Airport?
➡ “Getting a simcard! (or WiFi router)!”
There are quite a number of free WiFi hotspots in Korea, but many times the connection isn’t so stable. Also, isn’t it troublesome to ask for the WiFi password at every place you go?
Most importantly, personal information (such as your credit card info) may get stolen on public WiFi.
So, let’s check it out the best deal for SIM cards and WiFi routers in Korea.
1.Unlimited LTE Data Sim Card (Data Only)
Unlimited SIM cards are highly recommended to travelers who only use messengers or basic applications such as Facebook, Google Map, etc.
There are 3 major telecom companies in Korea: KT, SKT, and LG. We recommend “KT Telecom” because it offers wide data coverage in Korea.
Even if you plan to arrive at the airport really late at night or early in the morning, worry not! The KT telecom booth operates 24/7 at Incheon Int’l Airport.
Moreover, they have the precise size of SIM cards for each different phone type (nano, micro etc), and the price is same for all sizes.
1) Where can I pick up my SIM Card?
▶ Incheon Int’l Airport: KT Booth at the arrival hall near Gate 10 (06:00-22:00) or Gate 6 (24/7)
▶ Seoul: Office near Hongik University Station Exit 2.
💡 Tip: If you arrive at Gimpo Airport, Gimhae Airport (Busan) or Jeju Airport, please check the opening hours here
2) Price
There are 3 types of Unlimited SIM cards: 5 days, 10 days, and 30 days. You can use unlimited data (speed 5Mbps) before the expiry date. Not that data usage time starts to count off right after you redeem your SIM card at the ticket booth, NOT from the time you actually start using the data. Because date extension is not available, you need to buy an additional SIM card if you want to use it for more days.
💡 Tip : BOOK ONLINE (SIM card) to save time and money! If you book online now, you can get a 10% discount. Even better, you don’t have to waste your time filling in paperwork at the pickup venue. If you choose airport pickup, the telecom company staff will install the SIM card on your device & activate it for you!
