Why are two identical recipients displayed at the recipient of my iphone SMS?

This is no problem. Just delete the unwanted recipients.

In the list of SMS recipients, hold down the unwanted recipients, draw to the right, and then click Delete that pops up on the right.

This will not affect your news.

It may be that the text message sent by the mobile phone will be preceded by +86, but the number you sent with 9 1 doesn't exist, and the IPHONE can't recognize some China formats, so it is misjudged as two recipients.

Add:

You only need to delete a person's SMS dialog box, and the deletion method is as above. Or if you don't feel safe, delete them all and re-add the SMS interlocutor.
