When I try to log into verizon.com it is wanting to send a SMS verification to my Apple Watch "phone number" which is a Number Share and does not have SMS send capability directly to the number associated with the watch. I am not sure where in settings to change this so it sends the SMS to the main device number. I did upgrade my phone from an iPhone 15 pro to an iPhone 16 pro on Friday and I am not sure if this had anything to do with this issue.
