How to cancel Fetion friends by SMS?

You can't cancel Fetion friends by SMS.

There is no instruction to delete friends in the short message, but there is an instruction to add black. After adding black, the other party cannot send a message.

Edit SMS instruction: JH# mobile phone number or JH# Fetion number. If you want to add the black fly signal 123456789, edit JH# 123456789 and send it to 12520.

In addition, you can log in to the PC client and delete or add the number in the blacklist.

If you accept the other party's request to join, you can only delete it (and put it on the blacklist). But when the other party's mobile phone message is not a Fetion message, it will still be sent to the mobile phone. You can't refuse unless you turn on the shielding function of your smartphone.
