We have three phone cards that can be make calls from mainland China to USA and other countries.
You can check the three cards in this link:
http://www.ecallchina.com/?index=6 The Two-way phone card has proven very reliable over the the years. It can be used to make calls from almost anywhere in China including rural areaes. However this card cannot be used to make calls while using a cell phone on the China mainland. Cellular phones on the mainland cannot access toll free numbers.
The China Call Back Card and the China Call Back II Phone Card can call be used to make calls from China cell phone number but it cannot call from an extension number. For example, one cannot make calls from a hotel room. To get more information about how to make calls from China, check our pages in Chinese http://www.ecallchina.com/china/default.aspx
