Why do I receive Apple's mobile phone information, showing my account number instead of my mobile phone number?

If the other party uses imessage. The other party has set up an account. Then you received the account number instead of the phone number on your mobile phone.

Because imessage is used to send messages between apples, it doesn't charge communication fees to take away traffic, so it basically collects Apple's ID at first.

If you want to solve this problem, you can turn off imessage directly, but there is a charge for sending text messages.

To turn off imessage on iphone:

1, click "Settings" and slide down to Info.

2. Click on "Information"

3. Find iMessage and close it.
