When Fetion adds friends online, SMS is sent to the mobile phone.

The first problem is that the other party does not directly reply to your invitation to add, but sends you a text message. So the word "yes" becomes a message sent to your mobile phone, not a decision. I won't talk nonsense unless this happens. You can try if you don't believe me.

The second question, some friends think it is more expensive to reply directly to Fetion. They prefer to reply by SMS, so it's not a matter of setting. (Actually, the charges are the same.)

You know, whether you are online or not, as long as you send out an invitation to add and the other party replies directly, your mobile phone is inactive. There will be a prompt only after logging in to Fetion.

There was an asshole before, and I answered the question correctly, but the guy turned it off.

Fetion members sincerely answer your questions.
