Will Verizon be able to handle using the 2 sims in the Xs and XsMax? I keep reading about this. “If your phone is not unlocked, both plans must be from the same carrier. And, if a CDMA carrier -- such as Verizon, Sprint, US Cellular, Boost and Virgin -- provides your first SIM, your second SIM won't support CDMA.“ Does Verizon LTE make this CDMA problem irrelevant?
