Sort out the short message, click in and log in the mobile phone number. What's wrong?

Yes Near the Spring Festival, many platform merchants began to send short messages of various activities, among which some merchants launched the activity of clearing points, urging them to redeem the points accumulated by various consumers on weekdays as soon as possible, reminding them that some points will expire if they are not redeemed in time. At this time, the liar also stared at the "opportunity" of fooling people. Points are cleared and SMS points are entered. If you log in to your mobile phone number, something will happen and your personal information will be stolen. Therefore, you can't easily believe the text messages you receive when redeeming points, even those sent by your familiar customer service number.
