    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!

    it was good but I didn’t know how to register it !

    • Amy Bae 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?

    • Amy Bae 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)
