Send a message and ask someone to save your phone number. How to say it is more respectful!

First of all, it is important to pay tribute at the beginning. If people feel respected, they must use you instead of you. Just like writing a letter, you must add hello at the beginning. After that, you should explain who you are and why you need the other person's number. The more detailed, the more sincere. Be sure to add something like "sorry, please" at the end, which is more respectful. You can also add some greetings.

Format is also important. Don't enter all the words in one line. The first word "hello" can occupy one line and the content is in the second line. Don't write wrong words or use wrong punctuation. Be sure to check it several times before sending it.
