方便存储调用手机号和IMEI码的小工具，有些网络任务需要很多手机号和修改IMEI码，但是查询很麻烦，用excel又不方便，所以做个这样的小数据库用。(Convenient storage calls the phone number and IMEI code of small tools. Some network tasks require a lot of cell phone number and modify IMEI code, but query is very troublesome, excel is not convenient, so make such a small database.)
