Thank you for trying the Battery Extender Pro trial. The Pro features have now expired, but the Lite features will continue to work. We hope you have appreciated the benefits, please visit http://www.battery-extender.com/buy_ovi.php to purchase the Pro version. (Note, this is a free message)这个是短信内容，找不到发信人，只有个收件人：Battery Extender。这是什么意思呢.

感谢试用电量增容程序专业版，专业版试用期已到，但精简版仍可以继续试用，我们希望您对本程序感觉满意，请访问 http://www.battery-extender.com/buy_ovi.php 购买专业版。（这是一条免费短信）

估计是你买了什么软件然后到期了的一个提醒。
