The network unlock code AT T gave me doesnt work

I have a Galaxy J7 with I'm taking to Mint Mobile. I requested an unlock code, put in the new SIM, got the message: SIM network PIN blocked. Enter SIM network PUK, and tried entering in the unlock code AT T gave me. I got the error: Incorrect network unlock code entered. Since then, I've been through customer service a few times. First, they told me I had to drop the line, leaving me without the cell phone service I'm still paying for but no closer to a working phone. Second, they suggested a factory reset which didn't work either. Lastly, the "back office" took a turn and sent an email about the incorrect device and, of course, no solution. Thanks to AT T I'm now stuck paying two different services for a phone I can't use, a problem that has cost me time and money.



Anyone here have any suggestions for how to get my phone unlocked without paying a shady third party vendor which might not even work?

Hello @Mpark013,


We can definitely provide you with some more information on this.


If you've already submitted an unlock request for your wireless device and it was approved, you'll just need to follow these instructions to complete the unlock process for your device:


1. Power off the device, remove the battery, and insert a non-AT&T SIM card.
2. Re-insert the battery and power on the device with a non-AT&T SIM card.
3. The device will display ”Enter the device unlock code.”
4. Enter the unlock code.
5. Press OK.


If your device is displaying "Enter SIM network PUK" after you insert the SIM card that you've received from your new carrier, please keep in mind that this is separate from the device unlock code that we provided for you.


The PIN Unlock Key (PUK) code is used to unlock a SIM card and is usually displayed after your PIN is entered incorrectly more than three times.


You'll need to contact your new service provider to get the PUK code for your non-AT&T SIM card, as it is a different code than what we've provided for you already.


Let us know if you have any further questions or concerns.
