How to send text messages when the SMS with application is uninstalled in the mobile phone system?

I suggest that you restore the SMS program by brushing your computer, and download the firmware package and save it in the root directory of your mobile phone.

Then back up the phone and turn it off after backup.

When the phone is turned off, do the following on the phone:

1. Press and hold the volume down key and the power on key at the same time for about 10s, and the phone will enter the recovery mode.

2. Select "Clear Data/Restore Factory Settings" by pressing the volume up and down keys, and then press the power button to confirm "Yes".
