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?
