by Lou Martin, studioD. The 3rd Generation Partnership Project Long-Term Evolution technology, or LTE, is a 4G wireless network technology. LTE is built on the High-Speed Downlink Packet Access 3G network protocol, and offers high-speed wireless cellular network connectivity through mobile computing devices.
Depending on the wireless carrier, 4G can indicate either a UMTS or LTE connection. If your carrier doesn't yet support VoLTE and is a CDMA carrier, you'll see Enable LTE. This allows cellular-data use over the LTE network when available.
