I bought a locked straigh talk iphone 14 for cheap of marketplace and I knew it was locked. I just recently installed my icloud on it but because I thought Verizon could be use I downloaded the app and installed the 30 day network demo but after that it went into the activation and it does state its locked and so on. Now i can not get it off? it just keeps trying to activate the verizon esim. How do I delete all of thiss? thanks
