Excuse me, why does my Fetion always say that sending failed?

Cancellation of Fetion service or mobile phone arrears may be prompted in this way. Follow-up: My Fetion business is opened here! ! Then the phone bill is more! Still these questions! Answer: Send me your flight signal code and password to see if it is a network problem! Follow-up: ... then this will definitely not work! ! ! Can you tell me the method? Let me do it myself. Thank you! Answer: Your description is not detailed. I need to tell you what the problem is under my own operation.
