I purchased two iPhone 7s when they were announced, but unfortunately bought the T-Mobile version. I was aware of the whole Qualcomm vs Intel modem debate, but I didn't think I would want to switch to Verizon, so unfortunately I pulled the trigger before they had the SIM-free model available. I purchased the phones for full price directly through Apple if that makes a difference. My wife and I are sick of paying for a useless cell phone service (T-Mobile), so we want to switch to Verizon. We were planning on holding out for the iPhone 8 but we would really like to have cell coverage before then. Is there any option other than selling our iPhone 7s and purchasing Verizon iPhone 7s? Is this the type of thing Apple could help with at all? I feel stupid for buying the inferior iPhone 7 just because it was convenient, but being as they are advertised as the same product for the same price, I'm hoping there is a solution that won't end up costing me hundreds of dollars. Thanks!
