Advanced Calling 1.0 for Android Devices FAQs

What is Advanced Calling?

For Apple devices, check out our Advanced Calling 1.0 for Apple devices FAQs.

Advanced Calling 1.0 is a first generation suite of services enabled by VoLTE (Voice over LTE) technology. VoLTE is a new technology platform that delivers voice calls over the 4G LTE network instead of the traditional voice network.

The benefits of Advanced Calling 1.0 include:

HD Voice

1-way or 2-way video calls* (including support for video calls over Wi-Fi)

6-way conference calls

Simultaneous voice and 4G LTE data**

*Note: Not all Advanced Calling 1.0-capable devices support Video Calling.

**Note: Most 4G LTE Android smartphones today already support simultaneous voice and LTE data without Advanced Calling 1.0. However, some newer Advanced Calling 1.0-capable devices such as the Droid Turbo by Motorola do not support simultaneous voice and LTE data unless Advanced Calling 1.0 is activated.

What is HD Voice?

HD Voice delivers clearer, natural-sounding audio when both parties are using HD Voice-enabled phones that are connected to our 4G LTE network.

HD Voice is included in your existing voice plan at no additional charge, but must be added to your account in My Verizon. HD Voice calls are billed as standard voice minutes, according to your plan.

What is Video Calling?

Video Calling is a feature that lets you make an HD Voice call combined with real-time video.

Making video calls is as simple and easy as making traditional voice calls. If the person you're calling can accept a video call, you'll see a Camera icon. You can then select that icon to upgrade to a video call. There's no need to download an app or set up a new user ID to place a video call.

Notes:

Video Calling requires a Video Calling-enabled phone.

When connected to Verizon's 4G LTE network and known Wi-Fi access points, video calls will automatically hand off to Wi-Fi.

What is simultaneous voice and LTE data?

Simultaneous voice and 4G LTE data allows customers connected to Verizon's 4G LTE network to surf the web, continue a download, use an application, or use a feature like Mobile Hotspot while talking on a call.
