HI @Alexander101 

usually a Reset Network Settings would resolve the issue

and if you have an iPhone, update both the iOS and the Carrier Profile.  And check the "My Number" in the settings, does it show the correct phone number?  If not, you can remove the number first, reboot phone and re-enter it back to re-register for iMessage

 An you login to my account? You can update the number on there if it hasn’t been automatically completed. As for texting displaying your old number, what type of phone do you have? There’s a few solutions for Apple or android, so please let us know 

EDIT- I found both of these in a previous thread. Solution by @hTideGnow  , maybe they work for you?

Android- easiest way to fix is to uninstall the Google Message, reboot and reinstall 

iPhone- go to iMessage Settings and remove the phone number and reboot.  Then add the number back after to reregister iMessage
