Z7max can't send short messages with 322 rom, but it can receive them. What happened?

Hello, please try to restart your mobile phone, and then check the tariff and package of your mobile phone card with the communication company. Try to set the settings of the mobile phone-more wireless connections, set the default information application as information, and then set the sending SMS to allow all in the favorite Niu Dun-application management-permissions. If a third-party address book or security software is installed, please uninstall it as much as possible, and do not enter the mobile phone engineering mode to modify the network parameters. If there is any change, please do not enter the mobile phone engineering mode. The specific operation of double clearing is as follows: 1. Press and hold the volume increase button+power button when the mobile phone is turned off, release the power button after the mobile phone vibrates and restarts, and hold and hold the volume button until it enters the recovery mode; 2. Move the cursor with the volume up and down keys, move the cursor to the erasing data/factory reset line, and then press the power button to select it; 3. Use the up and down keys of the volume to move the cursor, move the cursor to Yes-delete all user data lines, and press the power button to select it; 4. At this time, the mobile phone will restore the factory settings, and then the mobile phone will return to the main menu; 5. You can also use the up and down keys of the volume to move the cursor to erase the cache dividing line, and then press the power button to select it; 6. Select the reset system now line with the power button, and the phone will automatically restart, and double reset will be completed.
