After upgrading from an iPhone 6s Plus to an iPhone 17 Pro Max, I'm facing a frustrating issue with constant full-screen notifications asking me to sign in to an Apple ID or MobileMe account. I'm not even sure if I have one of these accounts, but my phone keeps reminding me to sign in every time I unlock it. Even when I choose 'set up later', the prompt appears again within the hour. This didn't happen with my old iPhone; it only asked once during the initial setup. I really want to know how I can permanently disable these notifications.

It sounds like you may have some content on your phone that was either purchased with an Apple ID or linked to someone else's account. That’s why the system keeps prompting you to sign in. If that’s the case, the only way to stop the notifications without signing in is to remove the content causing the issue.

But I haven’t purchased anything from an Apple ID! I definitely don’t have an Apple ID, and these annoying notifications just won’t stop.
