Verizon Wireless will be rolling out VoLTE this week! As part of their new “Advanced Calling 1.0” initiative, the service is limited to the new iPhone 6 and iPhone 6 Plus. However, in order to take advantage of the service, you’ll have to manually enable it on the phone.
First, make sure the iPhone is activated and connected to Verizon’s LTE network. Next, go to Settings -> Cellular -> Enable LTE
By default, the Enable LTE option will be limited to “Data Only.” Tap on “Voice & Data” to enable VoLTE. It may take a few minutes to complete the process. Please note that some users have reported that the Advanced Calling 1.0 had to be enabled on the account BEFORE the iPhone would accept the change. To check this on your own account, you can simply log in at Verizon’s website and go to Manage My Account -> Change Features. Scroll down until you see the Advanced Calling 1.0 and HD Voice and make sure they are enabled.
