My iPhone 12 didn't transfer my cellular plan to my new phone during activation?

Thanks for you response. I'm trying to activate a new iPhone 12 Pro. I simply scanned a QR code with the new phone and then approved the deactivation of the old phone. Afterwards, the new phone is supposed to transfer the data plan.

The specific issue is that the iPhone 12 did not sinc with my carrier (Verizon). Currently, I have no cell service on the new phone, the old phone is deactivated, and Verizon support's response was "Gee that's weird. I've never seen that." I have listed this question under the iPhone 11 section because my new phone is not available in the pick list that led me here.

Again, thanks for the reply. I did purchase the phone new from Verizon. I am reading elsewhere that there is an issue activating the iPhone 12 specifically related to 5G and Verizon.

The QR code that I used came from Verizon. This is not a phone that came from an illicit source. I expect I’ll get the problem sorted through Verizon, but it may be that I have to get the right customer service person to accomplish the task. So far, I haven’t been successful there and that is why I posted the question here.
