VoLTE Benefits

FAQs

VoLTE (Voice over LTE) is the technology that provides voice service for your phone. VoLTE calls use our more advanced LTE network instead of our older wireless voice network. VoLTE provides superior voice quality and allows you to browse the Internet and use data-driven apps while on a call.

Most devices launched since 2018 support VoLTE. Below are examples of the more popular devices that support VoLTE.

  • Apple iPhone 8 and newer models
  • Galaxy S Series (S8 / S8+ and newer models) including Unlocked models from Samsung.
  • Galaxy Note Series (Note 8 and newer models) including Unlocked models from Samsung.
  • Galaxy A Series (A10, A20, A32, A50, etc.) including Unlocked models from Samsung.
  • LG G Series (G7 and newer models)
  • Google Pixel 3 and newer models
  • One Plus 7 Pro 5G and newer models

Capable devices already have the ability to enable VoLTE, and you can enable VoLTE today. Starting in July 2021, T-Mobile will be automatically enabling VoLTE on devices that may have it turned Off. This process does not require any action by you. This change is being done to support the upcoming retirement of Sprint’s older voice network.

You can find the VoLTE setting in the following locations:

Android Phones: Depending on the device, VoLTE will be in one of the following locations:

    Settings > Connections or Network & Internet > Voice Networks. Set the VoLTE toggle to On.

    Settings > Connections or Network & Internet > Mobile Networks. Set the VoLTE toggle to On.

    For Devices supporting 5G, VoLTE is automatically enabled as it is required for 5G.

Google Pixel devices will have VoLTE enabled and the toggle removed in a future software update.

iOS Phones:   

    iOS 13: Settings > Cellular > Cellular Data Options > Voice & Data > LTE, VoLTE On

    iOS 14: Settings > Cellular > Cellular Data Options > Voice & Data > Set VoLTE On

    For iPhones supporting 5G, there is not a VoLTE toggle.  VoLTE is automatically enabled as it is required for 5G.

Yes, if you already swapped your Sprint SIM card to a T-Mobile SIM ( T-Mobile Network Experience) then you are automatically using VoLTE. On devices with a T-Mobile SIM card, there is not a VoLTE setting as it is always enabled. Also, T-Mobile devices and Sprint devices using the T-Mobile SIM card do not show a VoLTE indicator in the status bar.

Android Phones: On most devices using a Sprint SIM card, the VoLTE icon should display in the status bar when available. For Google Pixel devices, “LTE” will display in the status bar during VoLTE calls.

iOS Phones: For devices using a Sprint SIM card, “Sprint LTE” will display in the status bar during VoLTE calls.

Wi-Fi Calls will transfer to VoLTE when Wi-Fi coverage becomes poor and VoLTE is available. For this automated transfer to take place, VoLTE must be turned “ON”.

As of June 2020, Sprint has updated most VoLTE-capable Android devices to prefer Cellular networks over Wi-Fi Networks.  For iOS devices, this change is included as part of iOS 14. This means that if your device has Wi-Fi Calling enabled, it will only be used if the cellular coverage in your area is poor. If you are on an active call using VoLTE and the coverage does decline, the call will attempt to transfer from VoLTE to Wi-Fi when the device is connected to a strong Wi-Fi signal.

Yes, if your calling plan is limited, minutes are used when making and receiving VoLTE calls.

No, data used by VoLTE calls does not count against data plan limits.

VoLTE calling is available in select Roaming areas on select devices.  Samsung and Apple devices currently support VoLTE roaming.  Sprint continues to work with our device partners to add this capability to other devices
