Can I not have multiple phone numbers associated to my Apple ID?
Because I have a second phone number on an old iPhone X, I am locked out of some services. For example:
Sharing Name and Photo not available
Sharing Name and Photo is not available because multiple phone numbers are associated to your Apple ID.
(This is from Settings - Messages - Share Name and Photo (to use with iOS 17 Contact Poster))
I have a second phone number so I can have a second account on Telegram, Signal, etc. There are other reasons for having second phone numbers too.
The only option I see to fix this is to deregister the second number and set up a second AppleID. But then none of my AppStore purchases would be available on my iPhone X.
What am I missing? Apple seems to be pushing me not to maintain a second phone number. Similar questions to mine are abundant, going back several years, but there is no guidance from Apple on what to do.
If having a second phone number on one AppleID is so problematical, why does Apple allow it?
