Is it possible to enable VoLTE on an iPhone 5s with the Carrier Update Hack? I think someone managed to do it a few months ago (see here and here). Im not sure how youd do it, though. By default, the Voice & Data option doesnt appear in Settings → Cellular, and officially Verizon only supports VoLTE on the 6 and 6 Plus, not the 5s or older models. The iPhone 5ss baseband processor (Qualcomm MDM9x15) fully supports VoLTE, so this shouldnt be a matter of hardware restrictions, right?
