This is so far the worst app ever created. I had to remove because it was working properly and now I am trying to reinstall it but it keeps installing Chinese version. Stay away from it. And I lost money since I still have some on my account that I can no longer use.

외국에 있는 친구들 때문에 국제전화 쓸일이 가끔씩 있는데, 오티오 음질이 가장 좋은것 같아요. 요금도 제일 저렴하고 ㅋㅋ 이런 어플 좀 많이 만들어 주세요~~

I am using app for few years because the app is afordable and the quality of phone call is good.However the app ask almost every the other week its update. This is not reasonable thing and much inconvenient for users.
