Question: Warranty replaced phone locked
I purchased a Phone6 through Verizon, and an apple care plan. All Verizon's phones are unlocked. My phone had a battery issue, and because the battery had swollen, Apple had to replace the phone. The phone Apple gave me is locked to Verizon. I'm not under contract with Verizon. Verizon was unable to help because they don't show the phone as locked (probably were looking at old IMEI number). Anyone have a solve for this issue? I've seen others on-line describing a nightmare trying to get it fixed, even with three way calls. I'm tired of paying Verizon's prices and want to switch to a different carrier. Not interested in replacing this phone, since it works perfectly.
