where do i find a UK customer support number?

Hi

Apple Support can be reached in the UK on 0800 107 6285.

You appear to be referring to Activation Lock, which prevents unauthorised use of the iPhone if it is lost or stolen.

If the iPhone is locked to your own account, but you are having issues with your credentials:

It may help to follow the instructions here:

• If you forgot your Apple ID - Apple Support
• If you forgot your Apple ID password - Apple Support

If you still need assistance, contact Apple Support or make a Genius Bar reservation, taking along your iPhone and your original proof of purchase for it:

• Contact - Official Apple Support (UK)
• https://twitter.com/applesupport
• Genius Bar Reservation and Apple Support Options - Apple (UK)

If the iPhone is pre-owned and is instead locked using the previous owner's credentials:

• Then it can only be disabled by the previous owner either entering their Apple ID and password on the device or by them removing the iPhone from their devices list in Find My iPhone via iCloud.com.
• If you cannot arrange for either of these steps to be taken, then you will be unable to use the iPhone.
• Apple will not advise you of the previous owner's contact details, nor will Apple pass your details on to them.

There is no way around this security feature.
