Apple Music on new iPhone 15 pro works only at wi-fi
Apple Music on new iPhone 15 pro works only at wi-fi and doesn't work at LTE. A new iphone 15 was purchased and everything was transferred from the old phone to it. But the Music app does not work on the mobile Internet, but only on wi-fi. The subscription has been verified, and everything is fine with it. The reboot was done. Is it unclear what the problem is and how to solve it?
iPhone 15 Pro, iOS 18
