How does Fetion 20 13 send short messages to non-friends on the computer? Please give some advice from experts.

That doesn't seem to be the case. I've never sent it like this. I don't know. I just found out that there are two ways to add friends after downloading the computer client. One is to add the other party's flight signal, and the other is to directly add the other party's mobile phone number, but it must be the mobile phone number. Unicom can't use Fetion! ! ! After the other party receives your Friend Request, as long as the other party answers "Yes", you are friends. You can click on his avatar to send him a text message. This computer client doesn't need traffic ..........................................................................................................................., so you need to dial 10086 to activate the Internet access function of the mobile phone, which is traffic. You will understand as soon as you talk to him. I have used Fetion for several years, and it is quite easy to use. I hope you can understand my words. Hey hey, you said to add 12520. You send it to others by airmail, and others will receive the message without sending it by airmail.

Hope to adopt.
