推荐答案
SMS规范( JSR 120 )表示您当时没有其他应用程序正在使用的端口，也没有下表中指定的任何端口.
The SMS spec (JSR 120) says you can't have a port that another app is using at that time, and also you can't have any of the ports that are specified in the following table.
表A-4:仅限SMS消息的端口号

奇怪的是，我看不到端口号的其他任何限制.我确定必须在某个地方进行设置，但是我在规范中找不到它.
Oddly, I can't see any restriction on any other values of the port number. I'm sure this must be set out somewhere but I can't find it in the spec.
但是，我强烈建议您限制端口号在1到65535之间.
However, I strongly suggest restricting yourself to port numbers between 1 and 65535.
