Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.

The signal is unstable. After watching videos for a while each day, the signal becomes extremely slow, and even mobile payment functions become unusable.

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.

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.
