I can’t add my phone number to Apple ID
I’ve recently switched phones and I’ve already given my old phone to my cousin. I tried to log into one of my emails and I had to get a verification code from my number on iMessage. It wasn’t sending, and I saw that it was signed into my (other) email, and I couldn’t get the code. So I tried to sign into my number on Apple ID to add it onto iMessage, but it asked me for ANOTHER code from my number which I couldn’t get because I wasn’t logged into iMessage with my number. Wtf do I do
