What is SMS charging?

SMS application providers provide some SMS services. After sending the message, you will incur monthly SMS fee or SP SMS service. These fees are only charged by communication providers on behalf of these SMS providers, so they are called SMS fees. For example, if you listen to the radio and participate in the activities inside, he will sometimes ask you what number to send the code to, and the charge will be explained in the program. As long as you send a message, the so-called collection fee will be generated.
