phone unlock for all carriers

Either it is not an AT&T phone, the phone is no longer in the AT&T database or the phone was never activated on the AT&T network and AT&T has no record of the IMEI.

when i enter the IMEI, my phone model is displayed o att website, it was brand new in original package, also, att  sim card is inserted already. maybe it was never activated ,because i opened the original package

AT&t requires minimum service before a phone is even registered in their unlocked portal. If you have no intention of ever using this on AT&t, or can't because you're not in the united states, return the phone and get your money back.

I discourage anyone from purchasing android phones off eBay, amazon, or anywhere else that sells new or used AT&t android phones unless they intend to use the phone on AT&t for the entire time they own the phone. It's not just about whether or not the phone can be unlocked, it's also about software updates which only occur when you are using AT&t for service.

Actually, that requirement has changed. You no longer must have minimum service on ATT provided the phone was paid for in full at the time of purchase. You now just need to wait 60 days to unlock, activating or using on ATT is no longer required.

Hello, @irakli! We understand the urgency in wanting your device unlocked as quickly as possible.

We need a few other details to provide the most accurate information:

1. Is the phone locked to AT&T? 
2. Have you been an At&t customer for at least 60 days?
3. Is the phone be in use on your account for at least 14 days? 
4. Is both the phone and your account paid off in full and in good standing? 

We look forward to your response and assisting you further.

AT&T will not be able to help you. EBay is not an authorized reseller of AT&T goods and there is no seller authorized to resale goods on eBay. You take your chances when you purchase anything off eBay.

You will never be able to unlock a phone that's not registered, and AT&T will not help you bypass their unlock policy in order to get it unlocked.

Resell the phone on eBay as AT&T locked and buy something that is already unlocked.

There is a reason AT&T phones sell cheaper than other phones. Now you know why

@formerlyknownas  thanks for the comment

I totally understand that now, but my question is that att website can recognize my phone and there is sim card in the phone from att, so i really think that att has the code in their database, and if they do, and there is no other issue with the phone (i mean fraud or something) , they could share it....

and i asked ,some of my friends could unlock it on att website the phones which they bought on ebay, it;s not like impossible thing

I will wait for att final response, maybe they can help :))
