I have lost access to Tinder and Transferwise because I moved between the UK and Australia and thus changed my phone number. Whatsapp also silently fails to send me private messages now, even after I went thru their official inbuilt 'I changed my number' process - only my group chats work now. The messages appear to send to the sender, they don't even know I didn't receive them. One of the worst examples I've heard is that Overwatch 2 not only requires a phone number, but they actually check with your carrier if it's a prepaid number, and if it is, you're banned. Sorry poor people, Blizzard doesn't want scum like you playing their game. Assuming someone's phone number never changes, or that they'll have access to their old and new numbers at the same time, is simply wrong and does not work. I haven't been locked out of Google yet, somehow, but maybe it's just a matter of time.
