Finally figured out how to activate the iPhone X (if you're still having issues). It's faster to call 1-800-MY-IPHONE. They will then call ATT/Verizon and once you confirm the new iPhone they will activate it instantly. I did this, my wife did this and my brother. It activates the phone instantly. Don't both clicking the "activate" button for hours. I did it for about three hours then just called in. My wife and I are on Verizon and my brother is on ATT.
