Can't swap to iPhone because of a firmware update.
Hello, if anybody could please help, it would be very much appreciated. I've been trying for hours to activate and swap to my new iPhone 11, but no matter how many times I try to factory reset or remove then put the SIM card back in, I always receive a message saying, "Firmware Update required. Be sure to update the firmware on the phone you are activating to ensure it works on the Expanded Network". The iPhone is completely up to date so there are no updates that I can download. I've tried several times to set up the phone with the SIM card that came in the envelope to no avail. I've been looking through everyone else's experiences with this and it seems like there is no real answer. I've never had any problems swapping phones before, so I'm a bit at a loss. Any help is appreciated. Thank you.
