Issue with unlocking Device
I am trying to port my iPhone XR over to Verizon. My phone is no longer on a contract with AT&T and I have completely paid off my installment plan. The account that my phone is on actually has a credit for $12 right now so there is no past due debt. I have gone to att.com/deviceunlock and when I get to the step that asks to type in my IMEI number, i get a notifcation stating my device has already been unlocked.
Once I get to the Verzon store and put a verizon Sim card in my phone, I get a message on my iphone stating sim not support because the (Verizon) sim is from a carrier that is not support under the activation server.
Someone please inform me on the best plan of action here so that I can make sure that my iphone will actually become unlocked and allow me to port over to verizon. Thank you!
