iPhone 6 LOCKED!

So strange, it said it was valid earlier! Don't know what to do

Amazon. I messed up the number, it says its ready for activation, please try the below, it worked for me when using this link: http://www.att.com/shop/wireless/byop.html

Nope... Still no luck even with the CORRECT IMEI which ATT have themselves admitted IS compatible but when I go through the unlock process I receive the same message:

Unfortunately, your unlock request was denied because:

The IMEI number [edited for privacy-please do not post personal or unique information such as but not limited to full names, employee ID numbers, email addresses, phone numbers, account numbers, etc.] you entered does not match a device compatible with the AT&T network.

Just sent them the following (does anybody have an email I can write to)

Hi guys, 

I have received an iPhone 6 for a birthday present (I live in the UK) and have been told by Apple that the phone is locked to ATT yet I receive the following when submitting an unlock request:

Unfortunately, your unlock request was denied because:

The IMEI number 359234062970621 you entered does not match a device compatible with the AT&T network.

However, when using this: http://www.att.com/shop/wireless/byop.html I am told that the phone IS! compatible with the AT&T network so why am I not being allowed to get my phone unlocked.

Apple have confirmed on multiple occasions that the phone is locked to ATT yet why is this "not compatible" when the phone has been confirmed on live chat, by yourselves as NOT being stolen, lost etc.

Thanks,

Tom

That simply means the IMEI is not in ATT's data base as ever having been used on the ATT network. Yes, it is locked by the Apple factory to the ATT network. But it doesn't get registered by the ATT automated system until it is activated on the network.

any advice on where I can go from here? Do not really fancy purchasing a sim to then activate it (being in UK) to then be able to finally get the phone unlocked!
