Receive error when trying to send a text message
Hello, I receive the following error when trying to send a Messages text message on my iPhone 13: "Invalid Number. Please re-send using a valid 10 digit mobile number or valid short code."
I followed directions to delete all messages from the recipient including the error messages, and I deleted all recent call history. Problem persists because when I try to send a new text message by posting the 10 digit mobile number of the recipient, Messages always adds a +1 in front of the ten digit mobile number.
How can I prevent Messages from adding +1 in front of the mobile number that I type in?
iPhone 13, iOS 15
