sms和pocket pc phone版本

short message service is a standard for sending short alpha-numeric messages (max 160 characters) between mobile phones in global system for mobile communications networks (gsm). it works much like paging, but with text, and most phones today have support for sms.
short message service是通过mobile communications networks (gsm)的全球系统在移动电话间发送short alpha-numeric messages（最多160字符）的标准。它像寻呼机一样工作，只是用于文本格式，现在的大多数电话都支持sms。
a key aspect of sms is that messages are sent through the mobile network operator's network instantly, without the need to manually connect to an internet service provider—sms messages are instantly delivered while e-mails need to be retrieved from a mail server by the receiver. also, if the receiver is not online—if the phone is turned off—the sms message is stored at the operator and forwarded when the phone is turned back on.
sms的一个关键特点是，通过无线网络服务器的网络立即发送，不需要手动连接到internet service provider—sms消息是立即发送，而e-mails需要通过接收器从邮件服务器上接收。同样，如果接收器没有在线—如果电话关闭—sms消息被储存在服务器中，当电话打开时再转发。
on pocket pc 2002 phone edition devices, you can manage sms messages much in the same way that you manage e-mail messages. the sms messaging component is integrated with the standard inbox application, allowing you to send and receive messages in the same way you send and receive e-mails. you can even forward and reply to e-mails as sms messages, and vice versa.
在pocket pc 2002 的电话版设备上，你可以和管理e-mail消息一样来管理sms消息。sms消息组件是一个完整的标准收件箱应用程序，允许你像收发电子邮件一样，收发sms消息。你也可以转发和回复sms消息，像电子邮件一样。
