How to use Fetion mobile phone? Is it free to send short messages by Fetion?

First of all, sending SMS by Fetion is free, free (mobile phone takes traffic by Fetion)

The landlord sends a short message to the other party by Fetion, and the other party can receive it without logging in to Fetion.

The short message you send will be sent to the other party's mobile phone in the form of short message.

But there is a premise:

The receiving mode of Fetion SMS set by the other party must be receiving SMS, otherwise the other party can only receive it like QQ the next time he logs in.

I hope my answer can help the landlord!
