How do I locate the IMEI on my iPhone 13
I just got a new iPhone 13. It is set to ATT and we can using tMobile. So the phone says SIM not supported. I'm told by the phone to go to the carrier to unlock. But ATT asks for' Don't know your IMEI? Call *#06# on your device, or go to your device settings to get it." But I'm just setting up the phone and I can't get to the settings, I guess because the phone isn't activated. It's not activated because the SIM is not supported. How do I get the IMEl # that att requires for unlocking this phone?
