How should I write a text message to tell my friends my new mobile phone number?

For important people, send text messages from the old number first, and then send them again from the new number. For example: Dear friends, I recently changed my number to a new one, please keep this in mind. (If you only send from a new number, some people may have settings to reject text messages from strangers). For very important people, send it separately and add a title. The specific content should be simple and clear at a glance. Just make it clear.

Changing numbers is very taxing. So try not to change your number as much as possible.
