Restoring the phone number associated with the iPhone is only necessary when the one displayed in iMessage is incorrect. If you have already managed to send messages via the iPhone iMessage service using your mobile number, you will not need to perform the steps described in this section of the article.
If you don't want the recipients of your text messages to know your mobile number, you can set up iMessage to use an email address
Step 2. Launch the Settings app
iPhone.
Tap the corresponding icon with a gray gear.
Step 3. Scroll down the appeared menu to be able to locate and select the option

Step 6. Turn on the iPhone again
After the 10 minutes indicated, keep the button pressed Power power on until the Apple logo appears on the screen, then release the button you are pressing and wait for the device to complete the boot process.

select the item Messages, activate the white cursor
placed next to the item "iMessage" and wait for the message "Waiting for activation …" which appeared in the lower part of the "iMessage" section to disappear.
