Praise by Forbes, The New York Times, PCWorld, and others has made BuyBackWorld one of the largest electronics buyback platforms online.
Unlocking your AT&T iPhone 4, iPhone 4S, 5, 6 or 6 Plus is FAST, EASY and FREE!
All you need to do is follow the simple instructions below:
1. Visit the Official AT&T Request a Device Unlock Form
2. Fill in the appropriate information where indicated on the form.
3. Once the form is complete, click Submit - That's it!
Why are we paying more for unlocked iPhones?
An iPhone device which is locked to AT&T will only work domestically on the AT&T network. Unlocking the device allows your device to work on any network, which makes the device worth more, allowing us to pass that extra value on to you, our customers.
BuyBackWorld Quick Pay™ is next day payment for your item through check or PayPal. This means your payment is processed the next business day after we receive your item Monday through Friday. Normal payment processing time is one week from when we receive your item so BuyBackWorld Quick Pay™ is basically expedited processing for your item to get you paid quicker.
PLEASE NOTE: If your item is received on a Friday, your payment will be processed on the following Monday.
Since we expedite your order to be paid the next day, there are additional costs involved in processing your item. We understand this option is not for everyone, but rest assured whether you choose our traditional payment time or our expedited payment time, you are still receiving a great value for your old products either way. Think about it like paying an additional fee to receive expedited shipping when you purchase something online. Quicker shipping comes at an increased cost and so does quicker processing of your item.
You still get paid through your preferred payment method of check or PayPal when you choose BuyBackWorld Quick Pay™, but we expedite the processing time of your item. Instead of issuing payment one week after we receive your item, payment is issued the next
PLEASE NOTE: If you choose to be paid via check, it still might take anywhere from
3-10 business days to reach you once we mail it. Unfortunately, we cannot control USPS transit times, we can only make sure we process your payment on the next business day after your item is received.
If you have any additional questions, please do not hesitate to email us at [email protected]

The ESN (Electronic Serial Number) is a serial number unique to each and every CDMA phone. A CDMA phone typically does not have a SIM Card and is usually Verizon, Sprint, Virgin Mobile, Boost Mobile, Metro PCS, Cricket or Alltel.
An ESN may NOT be clear for activation by a new user for the following reasons:
An ESN can also be referred to as an MEID (Mobile Equipment Identifier). This number is tied to a carrier and helps record the activity and status of the device.
Prior to our inspection, we will check to ensure that the ESN has been deactivated. If the ESN is not clear for activation, we will notify you via email and hold the item for 5 days. We will ask you to contact your wireless service provider and clear any issues that are causing your item's ESN to be active so that we can pay you the full amount.
Unfortunately, if you are unable to clear your ESN for activation, we will consider your phone to be in "Poor" condition, since it is only worth its value in parts and cannot be activated by a new user.
Verizon phones can now be checked through their "Activate Phone or Device" page.
The IMEI (International Mobile Equipment Identity) number is a 15 digit serial number unique to each and every GSM phone. A GSM phone has a SIM Card and is usually AT&T or T-Mobile.
You will usually find it printed on a sticker on the back of your cell phone or on the SIM tray of most Apple iPhones.
Alternatively you can have your mobile display its IMEI number by typing the following on the keypad: *#06#
If your handset displays more than 15 digits or is separated by symbols, please enter the first 15 digits only.
