Does it cost money to send text messages to a lot of people?

There are kinds of group software, some are free, and some still cost money.

But basically, SMS platform software does not cost money, and texting costs money.

Method of sending short messages in groups for free:

Baidu downloads Fetion first. Fetion is the premise that adding friends to each other is free to send short messages and send groups, but adding friends to each other is free. Similar to Fetion, there is iuu free SMS software, which is free only if you add friends to each other. After a month of trial, you have to pay to become a member before you can continue to use it. Wechat can talk in real time, but can't send text messages. There is also Yixin who cooperates with Netease. In fact, it is the application of Netease itself. The traffic generated by texting and calling with this software is free, but there are still many restrictions. If you can send short messages for free, but you can't send them in groups for free, and the short messages you send start with "Easy Letter Platform" and end with a long tail, you will be blocked from replying to a bunch of numbers.
