This is an Apple hardware limit, not a bug: each device can only ever create three iCloud accounts. The workaround is to create the account elsewhere. Jump to your situation below or read the methods.
The maximum number of free accounts have been activated on this device message is an Apple hardware limitation, not an error to repair. Apple restricts every individual physical device to creating a maximum of three iCloud (Apple Account) profiles over its lifetime, and this cannot be reset or bypassed on that device. Once a device has activated three, it will refuse to create a fourth new account. The workaround is to create the new Apple Account on a different device (or at appleid.apple.com or via iTunes on a computer), and then sign in to that already-created account on the original device, which is allowed because signing in is not the same as creating. There is no way to raise the limit on the device itself, so the fix is always to create the account elsewhere and then sign in.
Apple counts how many iCloud accounts have been created on a given physical device and caps it at three for its lifetime. This is a deliberate anti-abuse limit, so the message is the device enforcing that cap rather than a malfunction.
Because the limit is tied to the hardware and cannot be reset, you cannot create the fourth account on that device. You can, however, create it on another device or on the web, then sign in to it on the original device, since signing in to an existing account is not restricted.
“This one throws people because it looks like an error, but it is just Apple's rule: three accounts created per device, ever, full stop. You cannot reset it, no trick clears it. What you can do is make the new Apple Account somewhere else, another iPhone, iTunes on a computer, or appleid.apple.com, and then come back and sign in to it on this device. Signing in is fine, it is only creating a brand-new account on this specific device that is blocked.”
This message is Apple's lifetime limit of three iCloud accounts created per device, not a fault. It cannot be reset. Create the new Apple Account on another device, at appleid.apple.com, or via iTunes, then sign in to it on the original device, since signing in is not restricted.
If you need the new account active on this device and cannot use another, creating it at appleid.apple.com in a web browser is the most reliable path, after which you sign in on the device as normal. You can also submit your error to us for a tailored fix.
