Do you still have the deleted SMS of ID before the new Apple phone?

No, but iMessage is not necessarily true. Normal photos and text messages will not, unless you erase the data. None of these accounts are bound, so you can't take photos and make phone calls without logging in. Everything is normal.

Preparation tool: iphone7.
