I have had a shambolic experience today over the sale of my iPhone 8 that needed unlocked. I am still in the middle of the experience but it involves Apple and my cell phone carrier (Spectrum). I had to stop the sale and work on unlocking the iPhone. 6 hours into the mess, and I finally get to the cell carrier representative that knows her stuff. It turns out for permissioning reasons I needed a 5G sim card not a 4G sim card(came from my iPhone 8) in my new iPhone 12 I have (this was not explained initially). The iPhone 8 I have was a warranty replacement from Apple where Apple never notified my carrier of the exchange (thanks Apple care). My carrier has my old broken and replaced iPhone 8 information in their systems not the warranty replaced phone. Today Apple however verified my current iPhone 8 and me as the owner. Spectrum won't update their systems until they do their stuff (representatives were clueless) for the iPhone 8 and that requires the old 4G sim card and the updated information inserted in place of the old then the iPhone temporarily activated, then they will unlock the carrier lock off the iPhone 8. They then need to deactivate the old iPhone 8 and the 4G sim card that went with that device. The iPhone 12 needs a new 5G sim card and reactivated and permissioned properly as a new device (again) bypassing the initial muffed permissioning made by the original representative that helped me transfer service to my iPhone 12 initially. Things are a mess. There are months of lack of candor both on the part of Apple and Spectrum on this issue. This has delayed the sale of the cell phone (iPhone 8) by several days at the minimum. What should have taken 15 minutes has led to multiple hours of time wasted to get to a representative. Although my last representative was knowledgeable, I need a 5G sim card (don't have) and both phones out of service and me on a land line to do the manipulations to reset both devices. Problem as I found out is that the front line call center people cannot give direct dial numbers to customers, and that in addition they cannot dial out. This is absolute nuts. So I am now on hold until a supervisor with the proper permissions can call me. And I have to get a 5G sim card to make the fixes happen. Oh joy!.
