Verizon is a CDMA carrier, yes they use some of the same LTE bands, but their voice calls are CDMA. The unlocked phones sold by HTC only support GSM carriers like ATT and T-Mobile and their many MVNO's. You bought the wrong phone. Either switch or sell the phone and buy a Verizon specific model. Sorry.I got my unlocked phone delivered today. It looks amazing. I ordered the gray one. Unfortunately, despite having the necessary bands I was unable to get it to activate on Verizon. I saw the 4G LTE logo appear for a few seconds but it disappeared. I will be sending the phone back.
