I am changing my phone and need to transfer my music subscription from the old phi to the new number?
I have two iPhones I want to cancel the music subscription from one and add it to the other. How do I go about it? Thanks for your help.
You don’t have to cancel anything. The subscription is tied the Apple ID account, not to a device. (If you have the music subscription bundled with your mobile provider, then contact them for details.) Just register the new phone with the same Apple ID.
Afterwards you should probably reset the old phone to factory settings. What to do before you sell, give away, or trade in your iPhone, iPad, or iPod touch - Apple Support
