In March 2022, a Verizon agent (Daisy) via a messaging app offered me $700 trade in value for my iPhone 6s on the condition that I upgrade to the 5G Unlimited Start plan. My family line (4 lines) upgraded to unlimited and I sent my phone in. After realizing that I was not credited for my trade in I called Verizon on April 21. They told me that the agent was mistaken, the best they could do was offer $350, and since 30 days had elapsed I could not return the phone. Do not trust the promos they offer you. They use them to induce you into an upgrade and then will not honor their word. Buyer beware.
