If you spend 2 hours a day, I suggest you buy a monthly subscription, which is more than 80 hours a month, but you can call for five or six hours a day, and the call quality is good ~ I don't want a monthly subscription. In fact, domestic cards can also be used abroad, but only version 3.8 can be used, and the latest version 4.0 can be used monthly ~
It is recommended to buy it in Taobao!
