How much do you charge for receiving voice messages? How much do you charge for sending voice messages? Do I only charge for traffic or SMS?

When you send a voice message by SMS, when there is no internet connection (the voice size seems to be limited to 50K), it is a dime sent by ordinary SMS. Even if your friend doesn't use the internet connection to download, the SMS system will automatically judge to use the ordinary SMS channel. If you charge according to normal SMS, you may use up a little traffic.

Accepting voice is free, and if the other party doesn't need to click on the URL or something, there is no need for traffic.

It is free to accept SMS and MMS. Clicking on a website definitely requires traffic.
