저렴하게 데이터를 사용할 수 있어서 좋았습니다.
Easy to setup and use. Only downside is that you can’t track your usage.
Had to restart my S21 Ultra two times, but got it to work when I turned on the roaming data setting. From there it worked flawlessly.
One thing would be nice though, like if there could be a daily email of how much data was used and how much remaining. I basically had to “cross my fingers” and hope I still had data to use towards the end of my trip. I still don’t know how much data I used.
