How can I send a short message to my leading colleagues when I change my mobile phone number?

Pay attention to classification, classification, classification (say important things three times)

To colleagues: Hello friends, I'm XXX (your name). For business reasons (other reasons), I need to change XXXXXX to a new mobile phone number. Please forgive the inconvenience caused by the deactivation of the original mobile phone number (if the original mobile phone number is indeed deactivated). Please keep it. Thank you very much.

To the leader: Dear XX, due to business reasons (other reasons), my original number XXXXXXXXXXX will be discontinued in the near future, and now it is changed to XXXXXXXXXXX, for permanent use and long-term use. Please forgive the inconvenience, please save it. At the same time, I wish you a happy life and all the best.

To family: Send it in family groups at will, saving the cost of short messages.
