Fetion told me how to send text messages to strangers for free.

Fetion does not charge for sending short messages to strangers, and only mobile registered users send Fetion short messages to mobile phone numbers for free.

However, the PC does not support this function. You can only use Fetion on your mobile phone to log in to Fetion on your mobile phone. After clicking the address book, you can see all the user names in your mobile phone address book. Only mobile registered users can send free flying letters to people in your mobile phone address book, so it doesn't matter if this stranger is not your friend. You can first save the stranger's mobile phone number in your mobile phone address book, log in to your mobile phone address book again with Fetion, and then click the guest book to give it to this user.
