Carriers that use CDMA networks do not support simultaneous Voice and Data connections. However, LTE phones on these networks may support simultaneous Voice and Data if your phone and network support Voice over LTE.

  1. Open Settings and tap Connections.
  2. Tap Mobile networks.
  3. Tap the switch next to VoLTE calls to turn it on.

Please contact your carrier for additional details if you are unsure about your network.
