The mobile chipset maker MediaTek has announced its Dual 4G VoLTE (Voice over LTE) solution in collaboration with China Mobile network. It allows dual-SIM smartphones to support 4G VoLTE with both SIM cards instead of just providing support to the primary SIM card.

"MediaTek Dual 4G VoLTE solution"

The company’s Helio X30 SoC, which was introduced back in September last year, is the industry’s first chipset to complete the interoperability test of dual 4G VoLTE on the China Mobile network, said the company.

Regarding the Dual 4G VoLTE solution, MediaTek said in Press Release:

“Currently, 4G smartphones on the market allow only the primary SIM card to support VoLTE, while the secondary card can only use 2G/3G, which diminishes the calling and internet browsing experience. MediaTek’s Dual 4G VoLTE solution is highly integrated and optimized within the Helio X30 and future smartphone platforms, maximizing the usability of dual VoLTE with stable calling quality and high data transfer rates, offering consumers better internet and calling experiences.”

Since the MediaTek Helio X30 SoC is already shipping to OEMs, we might see the chip with dual 4G VoLTE for Reliance Jio in India soon.
