      It activated quickly. I connected without any issues after receiving the QR code in a matter of minutes. The ability to pay with cryptocurrencies was also appreciated; the entire process went well. I had no trouble staying connected during my journey because of it. For hassle-free internet access, BitJoy is a great option if you're planning a trip soon!

      The activation process is not complicated, and it was done quickly by following the steps. The payment method is also flexible. I tried credit card and cryptocurrency payment, and both were completed smoothly, and the payment was immediate. When I arrived at the local area, I scanned the code to connect to the Internet, which is very convenient and very suitable for travel.

      I'm giving 4 stars because the installation guide didn't mention that I had to set up the APN manually, and support also didn't immediately suggest it. I had to do some troubleshooting myself. Other than that, so far so good. P.S. I used it in Turkey and the APN is 'isp.'

      I purchased data from BitJoy for my father. Data worked as promised by the team. My father didn't face any problem at Toronto airport.

    • At activation. Install at home over WiFi and enable the line when you land at Incheon (ICN), Gimpo (GMP), Busan (PUS) or Jeju (CJU) - validity starts when the eSIM connects to a Korean network, not at purchase.
