App to transfer everything from iphone to new iphone
What is the app called to transfer data ect to my new iPhone ? I went into the store because I had sprint and got a new SIM card to be tmobile in my 11max pro because the 13pro Max had to be ordered . I just got the 13pro max in today. Do I need an app to transfer everything or should it be fine with iCloud ? Also do I take my chip out of my 11 to put into my 13 ?
