How to send messages without money? Because I often send messages in groups, about one hundred at a time, how can I send them without money? Some people say to send it by computer. Why?

First, you download a Fetion client, then register an account, which is your mobile phone number (only the mobile phone number can send and receive emails), then log in to your account to add friends and send them to your friends one by one. It's similar to QQ plus friends. After adding friends, it is convenient. Just right-click on the group, once and for all, it is free for the computer to send text messages to the mobile phone. It's normal for your mobile phone to reply to Fetion.
