Didn't buy the ticket, and the mobile phone received a reminder that the ticket was purchased successfully? What's going on here?

If you didn't buy a plane ticket, but the mobile phone received the message that the order was successful, it is likely to be a scam message or an error message sent by the system.

At the same time, check whether you order through formal channels. If the order is cancelled in time.
