So I hope this makes sense. I purchased a new iPhone 13 pro (new phone) and added a new line to my account (new phone number). My everyday phone is an iPhone 12 Pro (old phone). I want to take the new phone and use that as my everyday phone with my number from my old phone. I assume it as easy as just switching SIM cards between the two phones. Same carrier for both phones. The real question is how do I transfer all of my apps (etc) from my old phone to the new phone without messing anything up? Ultimately, I want the new phone to have my old number and all of my existing apps, while I will set up the old phone with the new number that I received when I added a line. Hopefully this is not too confusing.
