How to send text messages with traffic? I am Unicom's mobile phone number.

Using traffic to send text messages, you can use third-party software, such as QQ and WeChat, which all have this function.

1. Install the software and register an account to use it.

2. You need to add a contact account as a friend.

3. Select friends and edit the content to be sent.

Note: this kind of short message requires both parties to install the same software, and it requires a network to send and receive short messages.
