Is it true that Fetion sends short messages for free?

Hello, the fees for sending SMS and messages by Fetion are as follows:

For mobile Fetion customers:

If you choose the chat window to send messages, they are all free.

If you choose to send a text message, it is free to send it to your friends in a flying letter. Friends or non-friends sent to China Unicom and Telecom Fetion are charged.

For Unicom and Telecom Fetion customers:

If you choose the chat window to send messages, they are all free, but the other party needs to log in to Fetion software to receive them. If the other party is not online, you will receive it the next time you log in.

If you choose to send short messages, you can send 50 free short messages to your Fetion friends every month for free. Unable to send Fetion SMS to Unicom, Telecom and mobile users who have not been added successfully.

In addition, if you use the mobile phone client, you should also charge the mobile data traffic fee normally.

Please refer to it, thank you.
