Voice Over LTE (VoLTE) automatically provisions with any qualifying plan and requires no additional billing or system component. Apple Devices default the LTE network to Data only, which means the customer must turn on the VoLTE setting to be able to use VoLTE services.

See below for instructions on how to enable/disable the ability to use the LTE network for Voice calls.
