申请了一个ifree卡，
北京电信号打电话免费，
又不知道谁的号是北京电信号
花了不少时间熟悉了c#，改出来一个程序，
用应用宝导出xml文件，再倒进去即可。
代码如下。
public partial class Form1 : Form { public class phone { public string phoneName; public string phoneNum; } string fName; string sName; List<phone> flist = new List<phone>(); List<phone> slist = new List<phone>();
