Do not display mobile phone short message punching

What the subject wants to ask is whether the short message is turned on or not.

1. Check whether the mobile phone has downloaded third-party software, such as security guards. It is possible that the software intercepted the message. It is recommended to uninstall.

2. Verify whether the SMS blacklist function is set in the mobile phone.

3. Check the mobile phone notification settings, whether SMS notification is turned on and whether the notification mode is set to pop-up.
