Iphone and apple watch pairing
I have an Apple watch. I recently upgraded my iphone 6 plus to an Iphone 8 plus. My watch is not paired with my new phone and I cant get it to pair. when I go to my watch settings it will not let me erase and restart so I can pair it. It says I have to unpair it because there is activation lock. I erased my old phone and traded it and sent it back to att. I dont know how to fix this because I dont have my old phone. Also my Icloud is greyed out so I cant log in again. Thanks
