    Hi, I’m planning to stay for 6 months, so you do have plans for 90 days? Or do I have to buy one sim card every month?

    • KoreaTravelEasy    

      Hello, the longest data sim card is for 30 days. You can also buy sim card at convenience stores in Myeongdong or Hongik univ.

    The Young woman at the desk was very we’ll prepared and kind. She also showed me what to do to configure it in case it was necessary but as soon as I restarted the phone with the sim inside the mobile data appeared, so I didn’t need to use the guide. Internet runs very well on my Galaxy S7 edge! Thanks!

    • KoreaTravelEasy    

      Thank you for your comments about the SIM Card! Also we really appreciate your sharing of SIM Card rental experience with our partner company. Hope we can see you next time as well!

    Th*** R***     

    Hey, I will stay in Korea for 7 days, so when I book a SIM card for all days, do I get 3 SIM cards or 1 that is activated for the 7 days? Also, if I would have to get 3 SIM cards, can I pick them up at the same day or do I have to get them at the day when I would like to use them?

    • KoreaTravelEasy    

      Hello Tom, Thank you for your interesting KoreaTravelEasy! If you book 7 days SIM card, when you arrive at the pickup desk, they will give you 1 SIM card which you can use for 7 days. Hope it helps!

    Easy to find the booth, the clerk installed my SIM card for me, and it worked better and for less money than my domestic carrier hahahaha. Can I bring this home with me!? Travelers please note – the booths use a ticket system so don’t forget to get a ticket first before standing in line for a while like I did! And make sure you know which booth/carrier you go to there are several companies Korea Travel Easy books with and they have booths all over the airport.

    • KoreaTravelEasy    

      Thank you for your kind comments Rachel! We are very happy to hear that it was easy to find the booth and worked better. Also, thank you for your kind instruction about the line. Hope you had a great time in Korea!

    Hi, I have a Google Pixel will the sim card work for this phone?

    • KoreaTravelEasy    

      Hello Victoria, we have checked with our partner about your question! They told us that they think it will work but they need to try if it is working. The Google Pixel 2 was perfectly worked before. If you book and try but it is not working then they will fully refund you the payment. So please make a booking and try when you visit the information desk to pick up. Also, make sure you unlock the phone before you come. Thank you for your interests in KoreaTravelEasy!

    • KoreaTravelEasy    

      Oh..when you pickup the sim card, have you not checked it was working? usually the staff help you to register.
      So our customers are informed to check it before you leave the pickup desk, so it was no problem so far.
      But if you had difficulties to register, please email us ( then we will investigate asap!

    Hi. It’s a very useful guide, thanks! I was wondering if this prepaid simcard will be usable for my 3G based on data smartphone/Samsung note 3?

    • KoreaTravelEasy    

      Hi~ thanks for your compliment.
      for 3G based phone, the CDMA phone model (ex:N9009) is not working and others are working.
      If you let us know your phone model of Samsung Note3, we will check exactly.
      or you can check rent WIFI egg also if you are not sure the SIM card (search ‘WIFI’ in the search box on our website)
