Why can't the telecom card receive the information on the mobile phone information screen?

Cannot receive information notification when the phone is locked. Maybe the phone is locked. Please do not display the notification function.

You can: Settings-Lock Screen and Security-Notifications-Slide Show, Show Notifications From-Select Related Applications-Slide Show. Take WeChat as an example: find the "WeChat" icon-slide the switch at the back.

If not, the following methods are recommended:

1. Restart the phone to see if there is a signal problem.

2. Settings-Application Manager-Swipe Screen Options (All)-Find Information-Click Enter and try to clear the data.

3. Try to replace another SIM card.

4. Check whether the mobile phone is equipped with security guards or third-party SMS software, and test it after unloading.

5. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore the factory settings.

If the above methods still fail, please send the machine to the engineer to check the machine and deal with it.
