How to write a text message when changing phone number?

Dear family and friends, dear leader, my phone number has been changed to ******. If you need to contact me, please call the new number. This text message is a group message

Use your new mobile phone number to send a group text message to the friends in your address book, write "Hello friends, I am XXX (your name), this is my new mobile phone number, please help me." Save. The original mobile phone number is deactivated (if the original mobile phone number is indeed deactivated)." Then send it to friends in bulk. Then publish the same information on social platforms such as QQ Space and WeChat Moments.
