Dual 4G VoLTE Support in Indian Android Smartphones

With the advent of advanced 4G networks, Dual 4G VoLTE (Voice over Long-Term Evolution) support has become a significant feature for Android smartphones in India. This technology allows users to make voice calls and data calls simultaneously on both SIM slots of a dual-SIM device. Here, we explore the current landscape of which Android smartphones support this feature in India.

Smartphones with Dual VoLTE Support

India has a variety of Android smartphones that support dual 4G VoLTE. The following list includes some of the popular models:

Poco F1 Mi A2 Mi A1 (after Pie update) Redmi Note 7 Pro Realme 2 Pro Realme 3 Pro Mi Note 5 and later models (currently supporting dual active VoLTE service)

Chipset Compatibility for Dual VoLTE

The following chipsets support dual VoLTE:

Qualcomm Snapdragon 636 Qualcomm Snapdragon 660 Mediatek P60 Kirin 970

Some of these chipsets have inactive dual 4G VoLTE capabilities but will be activated through over-the-air (OTA) updates. Notably, some of these chipsets are found in smartphones like the Nokia 7Plus, OPPO F7, and Realme 1.

Dual SIM Dual 4G VoLTE (DSDV) Technology

Dual SIM Dual 4G VoLTE (DSDV) is a new technology that allows both SIM cards to connect to LTE networks and provision VoLTE simultaneously. This means users can use two Jio SIM cards in the same phone and both can make calls. This technology is supported by new processors from Qualcomm, Mediatek, and others.

Examples of DSDV Supporting Devices
