I set an online reminder for my friend, but when I saw him online, I didn't receive the reminder message. What's going on here?

There are several reasons for not receiving online notifications from friends: 1, QQ friends log in to QQ invisibly, so it is recommended that your friends not be invisible; 2. When your QQ number has been logged in online and your friends log in to QQ, there will be no SMS notification, but notifications will be sent through QQ system messages; (Not deducting the number of reminders) 3. The number of free reminders in the month is used up. Please click here to enter Super QQ official website, and log in with QQ number = "Personal Center =" SMS reminder number; 4. Set the receiving time period. For example, if you set the receiving time period as 10-15, but your friend is logged in as 18, this situation is unacceptable. You can log in by computer: mq.qq.com can log in to Super QQ official website Home = "Personal Center =" when he receives the SMS.
