SMS verification code and imessage
How do I get a verification code if I can't receive SMS's, It says invalid code when I fill in the security verification code provided. I need to add the phone number in order to select it in imessage so that I can start receiving SMS's. It seems to be a loop where because I can't receive SMS's, I can't enable SMS's. The iphone store wasn't apple to help and said I should phone in but that just said contact your carrier. Please let me know how to fix this issue to start receiving SMS's. Thanks
iPhone 7, iOS 13
