Thank you, that's informative, and I will pay attention to that. However, I know it's optional, but I do enjoy categorizing things, and I love using Google Contacts to do this. Whenever I receive in SMS a TOTP code or some sort of SMS notification, I add the sender's number to my Contacts. The "type" field or "label" of the phone number I set to "SMS notifications" instead of "Work" "Main" "Home" whatever. I decided I could categorize my friends' phones in the same way; rather than uninformative labeling of all their numbers as "Mobile", I could classify them as "Android" or "iPhone" and therefore, I don't need to open Messages to see which is which, I can identify them anywhere I have Contacts. (I don't run Messages on my Windows 10 Pro machine, for example, but I do use Contacts.)
