SMS notification of flight change

I also received this kind of scam message about changing my ticket, and I was almost cheated. They will try their best to trick you into changing the change fee to 20 yuan. If you receive the same information, then you may have met a liar. You can install a mobile phone housekeeper for your mobile phone, which has the harassment interception function of identifying fraudulent short messages, and you can know whether this short message is a liar at once, which is very simple.
