在php中创建SMS管理器并不是那么容易-实际上，要使一个可靠的SMS管理器并不是那么容易，调制解调器是一个特殊的品种. SMS服务器工具易于设置，可靠且功能丰富，因此我不会打扰，也不会设置SMS工具.

It's not that easy to make an SMS manager in php - actually it's not that easy to make a reliable SMS manager at all, modems are a peculiar breed. SMS server tools is easy to set up, reliable and feature rich so I wouldn't bother and just setup sms tools.

WRT调制解调器，我认为大多数调制解调器都可以工作.我们正在使用Cinterion TC65，它们可以很好地工作，但是我相信许多其他产品也可以很好地工作.

Wrt modems, I think most should work. We are using Cinterion TC65's and they work well, but I am sure many others will work equally well.
