Is the mobile phone good or bad when texting?

Four brands of mobile phones, MMS, SMS, can not be sent, or delayed, the information received at the wrong time. You can check the time zone setting of the user's mobile phone if there is no error in the setting parameters of the mobile phone information. If it is not GMT+8 time zone, you can correct it and restart the phone. I am testing the machine.

The reason is that the time of SIM card and service provider system is out of sync.

Note: GMT+8 is the time zone of China.

If not, use the instruction software reset method. Enter *#7370# when turning on the phone, the phone will restart, and it will be OK after the restart.

Note: 1. The battery should be charged. 2. The phone book or important information should be backed up to the memory card first. Only the data in the mobile phone will be lost, and the data on the memory card will not be lost.
