You can call China from your cellphone!
Just dial a China number from this app. The first 20 minutes and/or 20 calls are included FREE!
After that purchase more minutes from within the app. Much cheaper, and more convenient than a calling card.
注意：金国通只支援由美国致电中国（国码 86, 852）之间的通话务
Note: The call must originate in the USA, and the called number must be in China (country code 86, 852)
