How to remove iCloud from my iPhone?

What you need to do will depend upon whose ID this is.

Apple has two related features, Activation Lock ( Activation Lock for iPhone and iPad - Apple Support ) and Find My ( iCloud+ - Find My - Apple ), which are designed to prevent anyone else from using an iPhone, iPad, or iPod touch if it's ever lost or stolen. Deactivation of either requires knowing the Apple ID and password that set the feature, or by placing a special request to Apple to reset the device. This Apple ID information essentially defines the current ownership of the device.

If you do not know the required information, are not the signed-in owner, or do not have Apple accepted proof of purchase, get the owner of the account to remove the lock, or return the device for a refund, or recycle the device. The device is otherwise useless to you. If the owner is unknown and has not provided contact information as a message showing in the login screen, there is no way to contact the owner unless the person who gave you the device knows them.

Here are additional resources if you are the account owner, can find the previous device owner, or have an Apple accepted proof or purchase:

● Reset device if you can prove to Apple's satisfaction you are the owner:

Apple can completely reset a device if a person can provide sufficient evidence of valid ownership. This is done online* at: Activation Lock support request - https://al-support.apple.com/#/additional-support Apple says, "Proof of ownership documentation is required," but does not provide many details in the article as to what is acceptable proof. Prior to this official service Apple typically required the original receipt** issued by Apple or an Apple Authorized Reseller and documented provenance (so typically it would be the first owner who does this, or a descendant with legal proof of ownership transfer). Note that while this will let you get use of the device again, it will not help you with lost access to an account.

Is your iPhone activation locked? If it is activation locked to an Apple ID of yours, please try and recover access to that Apple ID at iforgot.apple.com. If you cannot regain access to that apple id and you can provide valid proof of purchase information, , you can start an Activation Lock support request.

If the iPhone is locked to someone else's Apple ID, you must ask them to remove the lock, apple will not do that for you
