I would like to ask all network programming experts how to send text messages to mobile phones on web pages.

There are several ways, 1. By fetion, but it's not very common.

2. To register Sina, you can use Sina's interface, but you also have to pay for sending short messages, which is similar to ordinary short messages.

3. Just buy an interface at the operator, that is, the mobile company.

Others are software and equipment such as SMS cats.
