Confused about ‘unlocked’ term.
I have two iPhone 7 Plus, 128 GB with Sprint. I wanted to pay them off because our contract lease is up. I was told that they can be unlocked once I pay off the phones. I switched to Verizon, but Verizon said that they cannot use the 7+ iPhone model that we have on Verizon service Even if they are unlocked by sprint. Is this correct? Because we ended up having to get two new phones through Verizon.
