亚马逊精确定位双向短信服务为用户提供一个长代码,该代码接受一条消息,并且可以挂接以回复单独的消息。 此服务可以处理多少条并发消息。
以下内容引用自频道短信 awssupport 长代码文档。
In the United States and Canada, sending rates for long codes are restricted to 1 message per second. This limit might be higher or lower in other countries and regions. If you send a large volume of messages from a long code, wireless carriers might begin to block your messages. If you send SMS messages programmatically, your applications should limit the number of messages that they send per second.
我希望这有所帮助。
