Hi ..
I found this in iCloud Help ..
If you’re no longer using an iOS device, Mac, or Apple Watch, you can remove it from your iCloud account. When you remove an iPhone or Apple Watch set up to use Apple Pay, Apple Pay is disabled for the device, and your cards are removed from the device, even if the device is offline.
Important: If you’re still looking for your Apple Watch, and it has Activation Lock enabled, mark it as missing instead of removing it. That way, your Apple ID and password are required to reactivate and use your Apple Watch.
If your Apple Watch has Activation Lock enabled, and you don’t mark it as missing before you remove it, Activation Lock is disabled when you remove it. You might want that to happen if you sold or gave away your Apple Watch but forgot to disable Activation Lock.
- Go to Settings on iCloud.com, then look at the My Devices section.If you don’t see the My Devices section, your account just has access to iCloud web-only features. To gain access to other iCloud features, set up iCloud on your iOS device or Mac.
- In the list of devices, click the one you want to remove.
- Click the Delete button next to the device. If you don’t see the Delete button, click Remove Device (below the device serial number or IMEI number).
Besides removing an iOS device or Mac from your iCloud Account, you can remove it from Find My iPhone.
If you remove a device from your iCloud account, and the device reconnects to the Internet, it reappears in the My Devices section of Settings.
If one of your devices isn’t listed, make sure it’s set up for iCloud with the Apple ID you used to sign in to iCloud.com. If it’s an iOS device, make sure it has iOS 8 or later. If it’s a Mac, make sure it has OS X v10.10 or later.
next to your device.
