If you never recover your Apple ID, you will lose access to essential Apple services like iCloud, App Store, iMessage, and FaceTime. You wont be able to download apps, update existing ones, or access iCloud backups, including photos, contacts, and documents. Additionally, if Activation Lock is enabled, you wont be able to reset or use your device if it's lost or erased. To recover your Apple ID, visit iforgot.apple.com website and follow the steps to reset your password. If you cant regain access, you may need to create a new Apple ID, but previous purchases and data will be lost.
