答案 0 :(得分：0)
以下内容摘自 channels sms awssupport long code 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.
