这个方法要求用户输入自己的号码时，以指定的细胞载体，但你可以向他们发送的文本免费（从你的角度）一样.NET发送电子邮件。

This approach requires your users to specify their cell carrier when entering their number, but then you can send them texts for free (from your perspective) the same as sending an email in .NET.

作为一个方面说明，主题行并不总是正确ptted间$ P $。大多数运营商只是转换一个电子邮件到SMS像 [主题] [正文] 但一些完全丢弃主题。

As a side note, subject lines are not always interpretted correctly. Most carriers just convert an email to sms like [Subject] [Body] but some discard the Subject completely.

也有提供这种服务（当然费用）的公司。最明显的是 Twilio 但快速谷歌搜索应该找你多一些。

There are also companies that provide this service (for a fee of course). The most obvious is Twilio but a quick Google search should find you some more.
