Cannot unlock Iphone 6

Have an older phone, paid off, that I am attempting to use while in Hong Kong, insert sim card and it states,"SIM not supported" When I attempted to unlock through the ATT website I received an error stating that the IMEI was wrong...please advise.

Hello @davidforrester,


We can definitely take a closer look into why your IMEI is not being recognized as an AT&T device when you try to Submit an unlock request. Please dial *#06# on your device to find the correct IMEI for your cell phone. Also, are you currently traveling outside of the United States? For further assistance, please let us know where your wireless device was purchased as well.
