Apple ID is an authentication method used for iPhone, iPad, Macbooks and other Apple devices. And there are chances that the phone number which you have entered in Apple ID might no longer be in use. Or you might have inserted a new SIM card in your iPhone and you want to change the existing Apple ID phone number to a new number. Whatever may be reason behind wanting you to change the number, there are multiple options available and that too without losing any media or data.
Apple automatically registers the phone number you use with your iPhone as a trusted phone number when you initially enable two-factor authentication for your iCloud account. This phone number is needed to authenticate your identity, giving your Apple ID an extra degree of security. A 2FA prompt appears on the trusted device whenever you (or anyone else) log in to your account on a new device for further sign-in security.
You may now easily change the trusted phone number for your Apple ID at any time. Follow these steps:
