This time, I wasn't sure how many GB I use per day, so I bought 100GB for one day to start with. The price was very cheap, and it was easy to use! After the first day, I got an idea of ​​my usage, so on the second day I bought a smaller amount, but it was very convenient as I could just press the refresh button and it worked perfectly. I would like to use it again.

I usually use an unlimited data plan, but I thought a 1GB/day plan might be okay for my child, so I tried this cheaper option. I set it up in Japan and was able to use it as soon as I arrived in Korea. It wasn't particularly slow and worked without any problems. I would like to use it again next time.

If you are Korean, don't buy this. This is only for non Korean passport user. This works so good. Just follow the instructions to verify you.

The internet is good, fast, strong, and uninterrupted, usable in all areas: on the mountains, outside the city, on the train, in crowded areas. Paying this price, with easy, convenient, and fast installation—just click once—is worthwhile. If you're going to Korea, get it. It's worth it.
