i bought a brand new sealed Verizon model A1661 iPhone 7 Plus from a private party. Everything checked out, she even shown me the receipt of full payment. The phone is currently working fine with my T-Mobile SIM card, however when I used phone’s serial number to check warranty status, I’m getting the message warranty info can’t be displayed because phone’s not activated. I activated the phone initially with the Verizon Sim came with the phone. When it got to the welcome screen then I swapped it out for my T-Mobile SIM card. Does apple honor iPhone warranty if the phone is used by a different carrier than the phone is intended for? She bought it from a Verizon store.
